Whilst I think it is important to approach the problem of climate change from all angles, I feel you are unduly haranguing demand-side activists. I've been witness to your views on this subject developing over the last few months but I maintain that I don't think its helpful to make this distinction, if only to tell activists, who are trying to improve energy efficiency and cut demand, that they are 'doing it all wrong'.

Besides this, I think there are some flaws in the argument that require further consideration. Within the few dozen governments that we should 'just' focus on, it seems to me from Strahan's map, with the exception of Canada, (and perhaps parts of Southern America, based on more socialist regimes) The governments who you would need to approach to curb supply, are the least likely governments to prioritise climate change above national profits. Kazakhstan has still yet to ratify the kyoto protocol and Iraq hasn't even noticed it was created. What's more, the coal producing countries you mentioned are those most robustly opposed to legal emissions limits - what makes you think they'll jump at the chance to stop taking coal out of the ground.

If America needs to be paid not to take coal out of the ground in order to convince them its a good idea, who the hell is going to pay them??
If supply is to be cut in countries where oil has not already peaked, and they are to be convinced by the Western world (consisting of the most oil dependent countries), how do you expect this to come about without the behavioural change needed to induce leaders to do the convincing on behalf of the oil dependent countries. Put another way, what leader would willingly ask a major oil producer to cap and reduce their output, while their population maintains a soaring demand for that oil.

More than anything, I think your analysis shows your pessimism for grassroots groups such as your local Transition group, which I note today has put together a programme of events with national level spokesmen for the largest transition community in the UK after a mere few months of existing.

Those of us choosing not to fly are a growing number, and your presumption is that any fuel I don't burn will lower the price so that other people will just burn it anyway. Again this underlines a fundamental pessimism that a critical mass of people making different choices has no impact on leaving fossil fuel in the ground. Though I think Monbiot could benefit from entertaining this tactic, it is one-dimensional to take this test mentioned as the only yard stick of success. By making different choices about the way we consume fossil fuel at an individual level we raise awareness in our own communities about these issues, engage others with this debate, question societal values about oil dependence and much more. If oil producing nations are expected to impose policies that cap oil production whilst Americans are still lusting after 4mpg monster cars, I wonder how long it will be before another oil producing nation is 'occupied' and such policies reversed.

It would be comforting to accept your arguement, Louise, to feel that our no-flying and transitioning are doing good, are keeping fossil fuels in the ground. However, the difference between the oil price and the production cost demonstrates that Chris's pessimism is justified. Fuels that you and I don't burn will be burnt by others entering the market.

Nobody is suggesting that empowering the leaders of fossil fuel rich nations to forego production is going to be easy but it is the only way to stop the carbon being burnt.

To reduce supply in the current situation without placing into effect a demand side plan that replaces fossil fuels with alternative energy sources is to beg for disaster on a massive scale. The above paper overlooks entirely the deep dependency that all current human socio-economic structures have upon fossil fuels. The author is in reality proposing that we accomplish by directive precisely what Mother Nature will require through the natural terminal decline of productivity inherent in the concept of Peak Oil. Soon global production of oil will begin its steady terminal decline, providing the restriction upon supply that the Vernons propose. Why take years convincing 30 nations to cut back on production when Nature will do that anyway? And who would enforce this? No one would have the incentive, neither producers, nor consumers.

The article reveals a shocking lack of perception of the catastrophic effects that would ensue upon the heels of such a decision. The global economy would suffer greatly, critical services and food supplies would be at risk, transport upon which 90% of global commerce and we all now depend so heavily upon would be negatively affected and immense pressure would be brought to bear upon the producing countries to increase production. The stronger nations might well say, "Sod it. We'll just take what we need with our military". Weaker nations would likely get very little and people will starve. To the rather naive suggestion that producing countries be compensated for cutting back, just how will that be done when the economy is going to hell in a basket?

Bottom line. It's just not that simple. The things that will help the most to cushion us against the approaching disaster via peak oil are (1) conservation and (2) heavy investments in alternative energy.

We don't have much time. Climate change is no longer humankind's most immediate problem.

Victor, the questions are:

Is natural decline in fossil fuel production fast enough to prevent dangerous climate change?

Is the damage to society by a faster reduction in fossil fuel use worse than the resulting climate change?

I would suggest that we can’t rely on natural depletion alone – Hansen’s business as usual scenario of just burning conventional oil, gas and coal takes us to 580ppm, that’s before looking at unconventionals or any positive feedbacks.

Regarding the relative damage of rapid fossil fuel loss or climate change, who can tell? What do you think about TEQs as a response to rapid fossil fuel loss?

Nobody is suggesting that empowering the leaders of fossil fuel rich nations to forego production is going to be easy but it is the only way to stop the carbon being burnt.

Impossible is the word that comes to mind when considering any political leadership proposing either supply or demand restraint.

The reality is any political party that proposes that recession is the way forward will either not get voted into power or will be voted out of power. This means the FF will be burned, almost everybody wants growth and a better way of life if possible - get used to it, and plan accordingly. Sadly, it looks like we don't have enough resources or time to waste on unproductive sidetracks.

Regarding the relative damage of rapid fossil fuel loss or climate change, who can tell?

Nobody. This is the big problem - nobody knows what the future will be, and politicians won't do anything that adversely affects society unless you can tell them with precision.

The current statistical probabilities are a completely inadequate tool for anybody to decide which way to progress.

As has always happened in the past, it looks almost certain that nature will decide the way forward, not humans.

If you understand the political process you will realise the world's politicians don't have the solutions to the approaching cluster of problems - so, don't rely on them for you and your family's future well being as it's very probably not a viable plan.

Xeroid.

to prevent dangerous climate change?

shouldn't it be to prevent MORE dangerous or ABRUPT CC?

how dangerous is dangerous? hasn't dangerous CC already occurred and is getting more dangerous everyday? it may indeed be politically "unwise" to state the truth in mass media, but is that so even in TOD?

Is natural decline in fossil fuel production fast enough to prevent dangerous climate change?

Is the damage to society by a faster reduction in fossil fuel use worse than the resulting climate change?

You must first answer whether dangerous climate change is even on the horizon to begin with. How bad will it be? How much will be affected? Not the alarmist Goristic dire pridictions that even the IPCC contradicts, but the solidly understood scientific evidence.

Richard,

I thought you were now persuaded. The IPCC synthesis report makes a big point that the rate of sea level rise is increasing. I think it is the economists rather than the scientists who are on squishy ground.

Chris

There is no increase in the over all rate of sea level. I noted before I would find refs and here are a few.

http://www.worldclimatereport.com/index.php/2006/12/04/decelerating-the-...

http://www.worldclimatereport.com/index.php/2007/09/14/sea-level-slowdow...

http://www.worldclimatereport.com/index.php/2007/02/09/shocking-facts-ab...

Also note that the amount of snow fall in the Antarctic is increasing, and together with the reduction in Arctic melting is a mere 5% over all reduction in ice between the 2.

I read as much as I can on both sides of the issue, as long as WorldClimateReport reviews PEER REVIEWED papers that contradict the premisses of AGW, I remain skeptical. Especially the hard core extreme alarmist Gorist dogma.

No don't give me the excuse that WCR is funded by Big Oil. A few months back Newsweek tried to do the same thing, but had to retract their own article when it was revealed that, yes, Big Oil in the past 20 years has put in some $18million into challenging AGW theory. But those who work in the theory in the same time frame were funded $50 BILLION. Thus who has money to loose at stake?

And no, the latest IPCC report is 7" to 23" in 100 years. The 7" is the current past average rise that has already been happening for the past 100 years of measurements. That rate has not yet been found to change and the IPCC report admits that.

Richard Wakefield

why haven't the investment bankers thought about creating yet another derivative that perhaps can make up some of the losses they are suffering from the subprime scandal - write up some put and call options on the coastal properties that have values directly linked to the sea level - the sea-level-rise believers can put their money in puts and doubters can put their money in calls? shouldn't the IPCC members get at least a meaningful percentage of their pay by the type of options according to their opinions?

Richard,

From the synthesis report:

Rising sea level is consistent with warming (Figure SPM.1). Global average sea level has risen since 1961 at an
average rate of 1.8 [1.3 to 2.3]mm/yr and since 1993 at 3.1 [2.4 to 3.8]mm/yr, with contributions from thermal
expansion, melting glaciers and ice caps, and the polar ice sheets. Whether the faster rate for 1993 to 2003 reflects
decadal variation or an increase in the longer-term trend is unclear. {1.1}

You other points are not relevant since you set the criteria that you need to see a change in the rate of sea level rise. Now you've seen it.

Chris

As long as the 'business as usual' people control the media, all the global warming scientists don't matter. It takes waiting till it's too late, till the hurricane surge comes over the levee, the orchards and vinyards run out of irrigation water, the forests burn down and take exurbia with it, and the Arctic ice pack disappears completely, before it is no longer possible to deny global warming.
Which is about where we are right now.
OK, so we denied tenure to people that talked about global warming years ago, when it wasn't too late. So we defunded people by denying them grants to gather the data that tracked global warming years ago, when it wasn't too late. It doesn't matter any more.
The question that matters now is, what can we do. Note, I am not asking what should we do, I am asking what can we do.
If we shut down oil production six years in advance of running out anyway, all that does is piss off the gasoline buyers, the commuters, and make them blame the Liberal environmentalists.
The Conservative denialists get off scott free and walk away with the money, laughing.
And what does it get us?
Better to just let us hit the wall six years harder. What difference does it make? We are in an irreversible climate shift. Six less years of burning oil and we are not going to save Greenland. Those six years are going to increase greenhouse warming by what, six percent? It's a compound interest thing. The last six months of running up your credit cards are not nearly as ruinous as the first six years.
We are not just concerned about the present amount of CO2 in the air, we are concerned about the melted snow that is no longer reflecting sunlight, the treeline moving north across the taiga and higher along the mountain sides, absorbing sunlight as the snow lies below the branches, the CH4 desorbing from the muskeg as the permafrost melts, and bubbling up from the wave stirred hydrates of the Arctic as the wave damping ice pack melts in the summer sun of the Arctic ocean.
Greenhouse gases from oil and coal are no longer the most important part of the global warming problem. The compound interest on the old greenhouse gases are what is more important.
You know, we went through this before in California. The ecofreaks got the government to buy up the last of the old growth forest. We saved about five years worth of lumber industry, and spent the next forty years with the rural areas bitching about us denying them good jobs at good wages, and subsidizing them by supplementing their taxes to compensate them for losing the employment. We got to compensate them eight times for every lost dollar of wages.
Why go through that again?
Hit the wall six years early and destroy the Conservatives as a political philosophy. Works for me.

Example of unsubstantiated hype. Greenland isn't all going to melt. The last time it was ice free was 180,000 years ago. Other past warm spells did not melt it all, neither will this one. Besides, it would take THOUSANDS of years to melt all that ice even if it warmed with no winters. You can't get past physical laws.

GW is happening, we have to live with it. We should not be spending a dime on trying to stop it as that will use up valuble resources we soon won't have. As oil depletes more people are going to starve to death than people who drown from higher sea levels. Oops, but that isn't happening...

We need to funnel our resources to preparing for a society with dwindling FF supplies. This hype over GW is distracting everyone from that goal, making the time when that realization does happen way too late.

Richard Wakefield
London, Ont.

No one is ahead of their time, just the rest of humanity is slow to catch on.

Greenland isn't all going to melt.

It doesn't all have to melt to cause serious trouble.  Total melting will raise sea levels ~21 feet, but 10% will flood cities, river deltas, etc.

GW is happening, we have to live with it. We should not be spending a dime on trying to stop it as that will use up valuble resources we soon won't have.

Quite wrong.  Many of the options for switching away from fossil fuels (esp. nuclear and some of the biofuels) also have a large impact on AGW emissions.  Relatively minor changes to system designs and incentives can address both problems simultaneously.

I think you are correct that we are beginning to see feedbacks that could ultimately dwarf the effect we have had so far on the climate, but I think you are incorrect that how we behave now makes no difference. Only half of our emissions remain in the atmosphere so drastically reducing our emissions should lead to reduced forcing since the atmospheric concentration of CO2 should begin to come down. We will know if there are feedbacks than need to be handled once we have done this, that is we will see if the carbon dioxide concentration continues to decline or if it begins to rise again. If the latter occurs, we should have time to remove carbon dioxide from the atmosphere ourselves since any feedbacks happening now are still small compared to our emissions.

Chris

Chris, to make the 23" in 100 years the rate must go up THREE TIMES! (for Gore ridiculous 20 feet it would have to rise 10x more than that. Gee, that is a MAGNATUDE more!)

But that rate change is not happening. In the World Climate Report summaries of REFEREED PAPERS is it quite clear that to establish the actual rate of increase is very hard. It goes through cycles of faster rates and slower rates, that at 7" per year has been going on for more than 100 years, long before we came along with FF buring.

If you read the summary in WCR you will note that the rate DROPPED between 1940 and 1993. And the quote you note is very clear that the current increase CANNOT WITH CERTAINTY be because of GW, it might, and most likley is, due to these small fluctations. Besides, this rate change is VERY small, just a few percent change.

Bottom line is the scare mongering of FEET or METERS increase in the next 50 years is PHYSICALLY IMPOSSIBLE.

So if all this melting is going and, and reviews in WCR dispute there is wide scale increases, where is all the water going? This is a serious, and theory breaking, problem. Theories stay or fall on their predictions. If the predictions of feet increases in sea level in the next 100 years does not pan out, the theory is in serious trouble. If there is no change in the rate over the next ten years, the theory is in trouble.

Please, don't just take the IPCC and the Gorites hook line and sinker, read papers that do not support the AGW dogma, there's lots of it. Hence I remain SKEPTICAL (not a denier) that we are contributing 100% to GW and hence can change the current trend.

And BTW, there is an astrophysis, who just died recently, who noted that the changes in the planets around the sun causes the solar system center of gravity to wobble, and with it the sun wobbles causing more or less activity, which affects our climate.

And you know this for a fact? Where have you published refuting this? And I do understand AGW, that's why I reject it.

Richard Wakefield

No, you don't understand it.  If you did, you'd understand that the glacial cycles correspond to Earth's orbital eccentricity and axial tilt/precession.  Jupiter influences Earth's orbital eccentricity IIRC, but that's already accounted for.

Could it be that one aging scientist could be right, and the entire IPCC is wrong?  Far more likely that the aging scientist is getting senile, and you're latching onto his claims because they align with what you want to believe.

These are different issues entirely. You were concerned with observed changes. Those are observed. How well projections work is another matter. It is not too hard to say that with the present trend of the rate of sea level rise doubling every decade we would see 3 meters a year in 100 years. Or we might project a linear rate of increase so that the rate is 3 cm/year in 100 years and it takes 30 years to get one meter. As the IPCC points out, the current rate of sea level rise is consistent with model expectations as is the observed increase in the rate. What we do know is that thermal expansion alone gives a couple of meters once the oceans have fully mixed so you'd need quite a lot of snow piling up somewhere to counter that. We also know that just a couple of degrees or so more warming gives us about 25 meters of sea level rise from melting which could come fast or slow. The science is beginning to favor fast. The reason we know about the 25 meters is because that is what it did last time. The maxium observed rate of increase for sea level is about 5 meters per century but that is likely a lower limit since decade level rates can't be discerned, so five meters in a decade could have happened. Some evidence of destructive flooding suggest pulses are involved in these kinds of things. At least meters in a half a century have been observed so this is not physically impossible. In our present situation of very rapid climate change, it might be more likely to be expected than not.

For those who like more direct evidence than the rate of sea level rise I think this link demostrates our situation very clearly. In another 40 years, the Mountain Ash that used to range down to West Virginia won't have a habitat in the lower 48. That is much less time than the life of a tree. You can see why mass extinction is expected from the climate change we are causing.

Chris

As the IPCC points out, the current rate of sea level rise is consistent with model expectations as is the observed increase in the rate.

That is NOT what the IPCC says. It clearly notes that the current (small) rate change cannot with certainty be known to be by anything other than normal variations. You even posted that quote.

What we do know is that thermal expansion alone gives a couple of meters once the oceans have fully mixed so you'd need quite a lot of snow piling up somewhere to counter that

Unsubstantiated speculation. The oceans will never "fully mix" it will always have warm sections, and deep cold sections, and have currents that circulate. It's gone on like that for 4 billion years.

The maxium observed rate of increase for sea level is about 5 meters per century but that is likely a lower limit since decade level rates can't be discerned, so five meters in a decade could have happened.
...
At least meters in a half a century have been observed so this is not physically impossible.

When and where did this happen? Post a link to the reference to support this. There is nothing in the past 100 year measurements that shows this. Go to the Tide and Currents website and give me the link of the place where that happened.

The graphs I've seen published shows that at the end of the last ice age the rate of sea level was much faster than today, but has since dramatically slowed down (to the current 7"/Cy on average) looking like the left half of a bell curve.

Richard Wakefield

Richard,

You need to read the synthesis report. Clearly, the increased rate of sea level rise is taken as supportive evidence. It is important to caution that past performance may not be inticative of future results. We don't know if we are settling into 3 mm/yr of if the trend will change in the near future, perhaps to 6 mm/year.

You clearly don't understand thermal expansion. There are temperature variations in the oceans. But those deltas are not what mixing is about. The deltas may remain the same (or get back to what they were) but the deep water is warmer with mixing. The whole scale shifts preserving the deltas. So, there are portions of the oceans now that have yet to warm, but very predictably will which leads to more thermal expansion.

It is during periods of catastrophic deglaciation that the highest rates of sea level rise are measured. You might want to read Hansen et al. in Philispohical Transactions this year for a masterful treatment. Read it carefully, and you'll be well repayed for the effort.

Chris

Chris, to make the 23" in 100 years the rate must go up THREE TIMES!

The pace of melting of the Greenland ice cap has tripled in just the last 5 years.  It is a fait accompli.

Chris,

The presentation at the Houston ASPO meeting from NASA GISS pretty much said that peak oil as typically portrayed here together with peak coal, similar to the way Dave Rutledge or the Energy Watch Group look at that, together look like Hansen's alternative scenario (which is lower than any scenario considered by the IPCC) rather than his BAU scenarios. However, NASA GISS is moving to the view that the level of dangerous climate change lies below 450 ppm CO2. You can understand why if you read Hansen et al.'s treatment of slow feedbacks in their recent Phliosophical Transactions publication linked here.

I feel that you are correct to point out unconventional oil, and I hope Dave will look at "acts of desperation" coal since that seems to be the basic model for coal in any case, but some depletion models look a lot different from the Hansen or other BAU models.

Chris

Hi mdsolar,

What are "acts of desperation" coal?

Thanks,
Dave

Hi Dave,

I'm thinking of very thin or very deep coal seams that we would not consider economical but which exist. The effort in Utah seems to me to be an act of desperation, but one could imagine even greater brazenness. I'm wondering if desperation could be quantified in mining deaths per ton? If so, then we have a long way to go to match early 20th centrury desperation levels in the US while deperation tolerance may be higher elsewhere.

Chris

Chris,

Due to depletion of reserves the peak of CO2 emissions might happen 60 years sooner than Hansen projects. The CEO of ConocoPhilips is on record claiming that oil production will never go above 100 million barrels a day. World oil production has declined in the last 2 years. Why keep treating the conventional nightmare CO2 scenarios seriously?

The article reveals a shocking lack of perception of the catastrophic effects that would ensue upon the heels of such a decision.

Not necessarily. Economies react sensibly to slow changes, catastrophic change comes only from catastrophic changes.

For example, we can say that a depletion in supply of 0.01% a year could definitely be compensated for without any significant trouble at all by efficiency gains, putting alternate means of energy generation, and so on; a depletion of 50% a year would definitely make a mess. So, somewhere between 0.01% and 50% depletion is a level which will allow for useful change but cause no economic disaster.

You also neglect to recall that the essence of the idea of peak oil is that a big drop in supply is inevitable. Whether peak oil is today or in 100 years, at some point there'll be a dramatic drop in supply - and we'll have to adjust then. Do you imagine that change forced upon us by physical limits is somehow less painful than change we choose to go through by treaty and law?

We're climbing down a cliff, and the rope is unravelling. So, we can either try to climb down before it breaks, or we can just hang around waiting until it breaks and drops us.

Hi Biff,

We haven't been introduced, but Chris has mentioned fondly the Lincolnshire life.
I believe empowering the leaders of fossil fuel nations to forgo production is not just 'not easy' but impossible without the backing of the majority of the global community.

While I suppose one could imagine circumstances in which people are aware of the problem, insist on the capping of production in oil-rich countries, and yet decide not to change their own behaviour, I struggle to think of an individual example where someone who fully understands the gravity of this issue has not changed their behaviour where they felt able. It seems that if you are convinced that individual action / government action on the demand-side does nothing, you lose the platfrom from which you could insist suppliers cut their production.

On discussing this further with Chris, I better understand that there are grounds on which to say that right now, the choice not to fly (etc.) does not directly stop any particular quantity of oil being extracted owing to the divergence of the cost of extraction and price of oil as you say, however the direct effect is inconsequential if it builds on the culture that is necessary to make direct caps and reductions. On both demand-side and supply side, attitude change is the most crucial factor, but I adamantly believe that if an attitude change can be achieved, the demand-side changes will happen as a consequence. If an attitude change cannot be achieved, attempts by a few enlightened individuals to try to cap supply will be either short-lived or have adverse consequences.

Hi Louse

Yes life's grand in Lincolnshire. I've just been watching the 20 new turbines being erected by Ecotricity at the end of my road. :)

There's no belittleing of demand side action intended. It is vital, just not sufficient. So far all the talk is about the demand side and supply side has been ignored.

You're quite right, culture is important.

Anyone who has studied the history of movements of social liberation will understand the importance of individuals and groups as examples. The Suffragettes in the UK, a tired black woman who wouldn't move from her bus seat in the US South, a skinny old Indian guy who went for a walk to make salt - individual change can have impressive effects in changing the culture as a whole.

Hi Louise,

I expect my post came across unnecessarily down on the demand-side activists. That is not my intention. The Transition Network has my complete support, not least as it shows how we can survive with less fossil fuel, an inevitable necessity due to both climate change and peak oil. The work done by the Transition Network makes the supply cuts I’m suggesting more palatable for our Government to support.

Regarding your point that the target suppliers are the least likely to prioritise climate change, fair point. But successful action on climate change absolutely has to curtail production from these same countries. The only question is how best to achieve it, bearing in mind the tight timescales within which we are to act. I don’t imagine it will be easy – only that proactive reductions in supply need to be considered, as an alternative approach, where today I don’t see anyone considering it.

It does seem politically impossible for an importing country to request production cuts, but doesn’t it just depend on how serious they are about climate change? Government’s frequently do things that are unpopular in the belief there will be a net benefit at the end of the day. Isn’t climate change science telling is just that, that there is net benefit from addressing climate change?

Am I pessimistic that a critical mass of people can leave fossil fuels in the ground? Yes – for two reasons. Time and magnitude. We’re told we have get emissions down fast, as demand reductions will at first only result in global reallocation there is a significant lag between demand reductions and any eventual supply response. Secondly there is just such a large body of people – literally billions who would dearly love to consume more fossil fuels if only your wealthy critical mass would give up some, relaxing the price a little.

Your final point I am in complete agreement with – we need demand side activists to raise awareness in order to facilitate the necessary supply side constraints. My concern lies with expecting partial success on the demand side (we can’t hope for more than a partial success) driving supply reductions.

A well considered response, sorry to catch you off guard so early this morning!

I'm more pessimistic about the (UK) government's response than the grassroots, seeing as the government continues to be lagging behind both citizens and emerging scientific data, but that's another story.

I will carry on not flying, while I lobby King Abdullah bin Abdul Aziz to stop all this oil producing nonsense :)

As a campaigner for the climate policy framework of "Contraction & Convergence"
(and for many years the Rural Development Liaison for the framework's founding organization,
Global Commons Institute www.gci.org.uk)
I too am a supply-side activist.

I should point out that the author seems to have heard George Monbiot on an off day -
he too is a supply-side activist in that he is one of C&C's most vocal staunch supporters.

Given our society's complicity in the unprecedented scale of genocide-by-famine which is now likely unavoidable,
with the predicted 50% cut in Africa's food production by 2020,
( www.irinnews.org/Report.aspx?ReportId=74481 )
we need to cut the supply of sources of GHGs at the most rapid pace that can avoid causing geo-economic collapse.

C&C will achieve this by defining nations' rights to emit GHGs,
thus limiting the global volumes of fossil fuels it is profitable to extract in any given year.

Campbell's Oil Depletion Protocol was very carefully designed for another, very specific, task -
and I've yet to see any suggestion that he feels it should, or could, be applied instead to re-stabilizing the climate.

The core difference between it and C&C is that it focusses on Nationally Owned (fuel) Resources, not on (emissions to) the Global Commons of the Atmosphere.

The core of C&C's negotiability lies in its phased equitable distribution of national rights of emissions to the atmospheric commons,
according to the size of national population (the convergence concept),
under an agreed annually-declining GHG budget (the contraction concept).

The Protocol offers no such basis in per capita equity of rights (de facto) to fossil energy usage,
nor the prospect of significant income from the S > N trading of those rights to maximize the rate of change out of fossil fuel dependency,
and thus it lacks the requisite incentives for sufficient support to gain critical mass.

By contrast, C&C now has the endorsement of the Nobel Laureates,
of the EU Parliament,
of the Africa Group of Nations at the UNFCCC,
and of India, Pakistan, and others.
(See Endorsements at GCI website).
Notably, we also have increasingly strong hints that China will adopt C&C at some point of its choosing.

If the Oil Depletion Protocol were re-written to allow the global distribution of an agreed annual ration of a set mix of fossil fuels according to per capita parity,
with agreed rights to trade surplus national fuel allocations (with revenues' spending ring fenced to GHG mitigation)
it would in fact approximate C&C and offer some of its incentives.

Yet negotiating that deal would mean nations' abdicating ("commonizing"?) their Ownership of their (ill-defined) strategic National fuel Reserves . . .

which looks likely to be a discussion needing rather more decades than we have available . . .

Regards,

Backstop

This supply side limiting, and contraction and convergence, both suffer from severe reality deficits. In reality no producer is likely to limit production for CO2 purposes - in the same way that no first world country is going to destroy its economy so third world countries can pollute more.

To effect any workable change you have to be more subtle than that. As a minimum you show producer countries how limiting production will increase prices and result in them earning even more from less (I get the feeling they've learnt that one already). You might also describe how mutual pacts can prevent military and economic strongarm tactics.

However in reality the main threat is coal. Its distribution and availability will make it the option of choice for the main world consumers. There is zero chance of getting them to artificially restrict supply, and even less of getting them not to use it. The only option therefore is to get it used in ways that don't release CO2. Carbon sequestration could be promoted, but I get the feeling that practical reality will continue to push that option into the "we're studying it" pile as far as coal power stations are concerned. However carbon sequestration for coal-to-liquids plants would seem plausible - part of the quid pro quo politicians would engage in to avoid mass green action when they suggest it as a solution to lack of oil.

Action that minimises the carbon released from coal based activities, particularly in terms of new research or plant designs, seems the most effective way of minimising the threat.

Several new coal power plants being planned in the USA and UK will test their government's commitment to emissions reduction, as well as the public mood.

There are two applications pending in the UK, one is likely to be approved by Kent council soon. Final decision rests with central government.

I hear that James Hansen is in vocal opposition to new coal power plants being proposed in the US. I guess approvals for new plants would be made at a state level?

AFAIK there are no actual CSS schemes in operation, not even pilot plants. The UK government abandoned a project to build a new gas power plant with CSS, in order to reopen the tendering process.

However carbon sequestration for coal-to-liquids plants would seem plausible - part of the quid pro quo politicians would engage in to avoid mass green action when they suggest it as a solution to lack of oil.

That doesn't help nearly enough.  Even if half the carbon going into a CTL plant is sequestered, it may still not be any better than coal-fired electric generation to run an EV and may well be worse.  The BEV can potentially be run by a non-emitting power source; the ICEV is inherently an emitter.

how about with carbon-free liquid fuels?

If you are talking about ethanol and biodiesel, there isn't enough biological productivity to run our society that way (with the possible exception of algal sources).  If you are talking about ammonia, you have the same end-to-end efficiency problem as hydrogen (see Ulf Bossel's critique of hydrogen fuel cells), plus even greater losses if you use it for combustion engines, plus toxicity hazards from leaks.

SSAS is a great idea for fertilizer, but pitching it as a way to turn wind power into vehicle fuel runs into the same issue as hydrogen; you can get several times as much energy to the wheels by running it through batteries instead of chemicals.

ethanol and biodiesel ain't carbon-free.

ammonia doesn't have to be reformed back to hydrogen to be used thus the end-to-end efficiency problem is not inherent to ammonia. if the toxicity of ammonia is indeed a problem, the world would have been very different today.

SSAS is a great idea for fertilizer, but pitching it as a way to turn wind power into vehicle fuel runs into the same issue as hydrogen; you can get several times as much energy to the wheels by running it through batteries instead of chemicals.

without getting into the difference between ammonia and hydrogen again and the difference between fuels in liquid or other forms, just ask oneself: where are the majority of the wind/solar resources situated on earth? is there time and is it practical to replace majority of the ICE powered equipment into battery powered before this whole argument about CC becomes meaningless?besides, ain't batteries basically heavily packaged or equipped chemicals?

ethanol and biodiesel ain't carbon-free.

No, but they can be carbon-neutral (and some methods of production, e.g. perennial grasses, sequester large amounts of carbon in the soil).  So long as we push our carbon requirements low enough to meet them with available productivity, that's not a problem.

Ethanol and biodiesel have the advantage of compatibility with existing infrastructure.  Further, ethanol and biodiesel spills do not present acute public health hazards.

ammonia doesn't have to be reformed back to hydrogen to be used thus the end-to-end efficiency problem is not inherent to ammonia.

Hogwash.  Any decrease in chemical energy means less energy available at the point of use.  Further, if you mean you intend to use ammonia as fuel in a combustion engine (perhaps 40% efficiency) instead of a fuel cell (60%), you take an even bigger loss than the one for hydrogen shown on page 36 of this presentation.  That would put you down to about 16% end-to-end.  It would take roughly 5x as much generating capacity to do the job with ammonia compared to batteries.

where are the majority of the wind/solar resources situated on earth?

The entire US could be powered by the land-based and nearby off-shore wind resources.  The entire world could be powered by the sun falling on a fraction of Arizona.  With that much local abundance, why should we care if "most of it" is in places like southern oceans and the Sahara?  Why should anyone living today care?

is there time and is it practical to replace majority of the ICE powered equipment into battery powered before this whole argument about CC becomes meaningless?

You beg the question of compatibility of today's ICE-powered equipment with ammonia.  Short answer:  it isn't.  Batteries are going to be far cheaper, quieter, cleaner and safer than building 5x as much RE generation for the sake of powering combustion engines with ammonia.

Ethanol and biodiesel have the advantage of compatibility with existing infrastructure. Further, ethanol and biodiesel spills do not present acute public health hazards.

you can start a new thread on them but they are beyond the scope of the original question.

Hogwash. Any decrease in chemical energy means less energy available at the point of use. Further, if you mean you intend to use ammonia as fuel in a combustion engine (perhaps 40% efficiency) instead of a fuel cell (60%), you take an even bigger loss than the one for hydrogen shown on page 36 of this presentation. That would put you down to about 16% end-to-end. It would take roughly 5x as much generating capacity to do the job with ammonia compared to batteries.

no need to get "poetic" here. decrease in energy available is inevitable by the fundamental laws of thermodynamics. the only question is by how much, at what cost and what is the lead time. 40% efficiency of ICE is not an inherent limit for ammonia given its high octane number. 60% of fuel cell efficiency is desirable but how long will take and at what cost?
why one has to stick with the conventional electrolysis+HB approach to ammonia synthesis? SSAS gives energy conversion efficiency of more than 70% - more efficient than hydrogen production from electrolysis. even with the 40% efficiency of the existing ICE, the end-to-end as you defined should be 28%. now is battery lossless or 100% efficient? the highest efficiency in charging a battery alone is about 85% - let alone by ignoring the leakage and loss to the internal resistance during discharge. then there is again the question of how will the energy be transported? at what cost?

The entire world could be powered by the sun falling on a fraction of Arizona. With that much local abundance, why should we care if "most of it" is in places like southern oceans and the Sahara?

what conversion efficiency is assumed? the efficiency of the free market will sort the question out if a time frame for CO2 reduction is set.

Why should anyone living today care?

that is the fundamental difference indeed.

Batteries are going to be far cheaper, quieter, cleaner and safer than building 5x as much RE generation for the sake of powering combustion engines with ammonia.

the 5x assertion not withstanding, quieter, cleaner and safer - to the end user - not in dispute, far cheaper is dubious given the limited battery life and complete replacement of equipment. the question again is the time. an ideal solution in distance future can hardly change BAU for now. then, the original question is not just for personal vehicles - which could be more idealistically replaced by bicycles - how about farming, industrial machineries, truck fleets, ships, planes and power station in population centers far from where the RE can be gethered?

you can start a new thread on them but they are beyond the scope of the original question.

Why are you objecting to a one-sentence treatment of the issue?

I swear you must be blind.  The point is that any conversion from electricity, to chemical fuel, back to electricity has a fraction of the end-to-end efficiency of batteries.  That's any conversion, whether it involves ammonia or not.  Using heat engines instead of fuel cells just makes the efficiency even worse (more steps with inevitable entropy increases).

Hydrogen is not the answer because it is too lossy.  Ammonia is just a way to store hydrogen more easily, and has roughly the same losses.  You have utterly failed to address this issue.

now is battery lossless or 100% efficient?

Modern Li-ion cells are 95%+ efficient.  Several chemistries can charge about as fast as a fuel tank can be filled.  The energy density isn't as high, but you have no material to handle or leak.

what conversion efficiency is assumed?

You utterly miss the point.  It makes no sense to take a system which has to ship energy from Minot, Amarillo and Los Cruces to Chicago, Houston and Los Angeles and build it around a medium needed only if you are capturing energy in the Southern ocean west of Perth for shipment to New York.  It makes even less sense if you won't need such shipment for 50 years, if ever.

We need ammonia for fertilizer, sure.  Electrolytic ammonia for fuel?  The huge losses make it uncompetitive with electricity used directly, and there are other competitors for the niche it would occupy.  They need to be evaluated on their merits, including the direct and indirect carbon emissions/sequestration.  You haven't done that.

Why are you objecting to a one-sentence treatment of the issue?

no objection. just trying to focus on the question. no matter how disagreeable KongFuZi's doctrine is, some of his words are still helpful - without clearly defined terms, no argument can go well.

The point is that any conversion from electricity, to chemical fuel, back to electricity has a fraction of the end-to-end efficiency of batteries. That's any conversion, whether it involves ammonia or not. Using heat engines instead of fuel cells just makes the efficiency even worse (more steps with inevitable entropy increases).

are batteries not doing the chemical conversions themselves? the point here is not against batteries and fuel cells - they do have their places - albeit limited and slow coming - in the whole picture, it is what can make the biggest and quickest differences.

Modern Li-ion cells are 95%+ efficient. Several chemistries can charge about as fast as a fuel tank can be filled. The energy density isn't as high, but you have no material to handle or leak.

can you point out one battery charger that is more than 86% energy efficient? how long can the claimed efficiency of the Li-ion cells last? anyone used a laptop computer for a few years should have some feelings about how they behaves.

It makes no sense to take a system which has to ship energy from Minot, Amarillo and Los Cruces to Chicago, Houston and Los Angeles and build it around a medium needed only if you are capturing energy in the Southern ocean west of Perth for shipment to New York. It makes even less sense if you won't need such shipment for 50 years, if ever.

if there is a system for transporting the hydrocarbons in existence, it can be used to transport ammonia without much modifications. if there is none, the economics will sort the question out provided that the urgency of combat PO and ACC is priced in.

We need ammonia for fertilizer, sure. Electrolytic ammonia for fuel? The huge losses make it uncompetitive with electricity used directly, and there are other competitors for the niche it would occupy. They need to be evaluated on their merits, including the direct and indirect carbon emissions/sequestration. You haven't done that.

ammonia doesn't have to be from electrolysis - there are SSAS and thermal-chemical synthesis without the forming of H2. if you start a forum for the evaluation of the merits of various alternatives, people from the ammonia fuel network would be more than glad to participate and to provide as much information as needed.

to close, let me quote LaoZi: the good won't argue, the arguer ain't good. had we been good (by LaoZi's definition), we wouldn't even have the need to be here arguing...

Batteries are not required for electrified rail (intercity & Urban), electric trolley buses and bicycles.

Notably, we also have increasingly strong hints that China will adopt C&C at some point of its choosing.

I dont beleave that for a second. They may pay lip service to that but there is no way China is going to reduce their consumption of FF. They're going everywhere they can to secure more sources. They want to displace the US as a super power. Military spending in China is around 15% increase each year. They have increased contracts with African nations in Arms-for-Oil deals, and they are currently training pilots to take off and land on aircraft carriers they plan to build soon. They are also preparing to send a man to the moon.

sorry to butt in.

This question of optimism and pessimism is very subjective. Which usually is taken to refer to individual interpretation of their experience and prediction of their future. On such a scale this is easily dismissed for either side of the discussion.

However, when large groups of people side with optimistic/pessimistic views then momentum for action is not easily dismissed.

In simple terms this could be called "mood".

To change the mood of many people is not easy and can be a slow attritional
process. Sudden shock can work more abruptly.
However, the actual shock must be easily recognisable. For the majority on this planet PO and GW are still abstract concepts, if known at all.

Until Katrina I thought single events could move opinion. It did, temporarily, but now I realise we are hardwired into 'moving on' individually, and as groups.

You may have to affect 6+ billion people directly to change them.

Only after the second world war did such an immense effect on humankind change the mood so strongly.

Close.

But the "shock" needs an outside unaffected source.

Otherwise Collapse ensues.

Arkansaw of Samuel L Clemens

Dear Chris,

I wrote this out to clarify my own thoughts, but I deemed it worth posting.

Clearly the earlier fossil fuel supply limits - whether geological or voluntary - are reached the better for climate change, but the more painful the 'Peak Oil' adaptation problems. Since in a technical sense demand (moderated by price) can never exceed supply, the Peak Oil question really is how painful the demand destruction will have to be to bring demand down to meet the limited supply. The earlier supply limits are reached the worse this pain will be. The oil price thus becomes a rough measure of this pain (and at almost $100 it is already a fatal level of pain for many around the world).

However, since CO2 concentrations are also threatening to reach fatal levels for even more of the world (as you have highlighted there is enough coal to take us way past acceptable levels, even, to my understanding, in light of the latest coal reports), you are suggesting that we need to bring the fossil fuel supply limits forward, despite the increased pain of higher prices and even more vicious demand destruction this would cause. This becomes the lesser of two evils. Sadly I have to agree. And of course we would both agree that any demand-side improvements that can be made (such as those that TEQs would stimulate) to lessen the viciousness would also be most desirable.

since CO2 concentrations are also threatening to reach fatal levels for even more of the world

What do you mean by "fatal levels"? CO2 will never reach consentrations that will kill people as a gas. CO2 levels in the geological past were 3-4 TIMES the current levels and life flourished. In fact it is thought that such high levels made plants grow so fast that it is the only way that such times supported the Sauropods that fed off them. The IPCC scenarios predict CO2 doubling current levels. No where near geological past levels.

Richard Wakefield

No one is ahead of their time, just the rest of humanity is slow to catch on.

Yes, I meant the climatic consequences of the concentrations. Apologies if that wasn't clear.

But those have not been proven, only speculated. If the CO2 levels in the geological past were 3-4 times higher, then how can 2x higher be "fatal"?

Richard Wakefield
London, Ont.

No one is ahead of their time, just the rest of humanity is slow to catch on.

"Geological past" is a nebulous term, but according to the World Health Organisation 150,000 people are dying each year as a consequence of climate change ALREADY.

We have so far seen around a 0.8 degrees C rise in temperature over pre-industrial, and around another 0.6 degrees is already 'in the pipeline' and effectively guaranteed.

I see nothing controversial about the claim that the consequences of climate change are proving fatal for ever-increasing numbers of people.

Higher CO2 levels mean the plants don't have to have as many stomata. Stomata bring CO2 into the plant, and leak H2O in return. So if CO2 levels are higher, plants evolve to have fewer stomata, lose less water, and grow in drier areas.

"Geological past" is a nebulous term, but according to the World Health Organisation 150,000 people are dying each year as a consequence of climate change ALREADY.

That is unprovable. It is just as unprovable as claiming Katrina was because of climate change. If climate change wasn't happening would that same number of people have died? There is no way to prove that. Besides the article is also clear in the same paragraph that "Measurement of health effects from climate change can only be very approximate." So their calc is highly suspect, by their own admission.

BTW in the article you linked it said:
"Globally, 1998 was the warmest year and the 1990s was the warmest decade on record"

Actually that was recently proven mathematically to be false. The hottest times on record is still the 1930's. Who ever did the calc for recent numbers screwed up.

Richard Wakefield
London, Ont.

It's a bogus claim.

No one is ahead of their time, just the rest of humanity is slow to catch on.

Well, specific individual events being linked to climate change is unprovable, just as it's unprovable that any given driving death is caused by blood-alcohol levels - but that doesn't mean there isn't overwhelming evidence that drinking and driving kills people. And yes, numbers are approximate. Again, this doesn't mean that the trend is any less clear, or that the calculations are 'highly suspect'.

And with regard to the 1930s claim, I suspect you know the truth of this, but because I've got nothing better to do.. In August this year (after the release of that WHO report) some minor revisions were made to the NASA GISS data to account for previously unnoticed differences between two sources of US temperature data used. None of these differences are statistically significant, but where 1998 (1.24 ºC anomaly compared to 1951-1980) had previously just beaten out 1934 (1.23 ºC) for the top US year, it now just misses: 1934 1.25ºC vs. 1998 1.23ºC. The difference is a few hundredths of a degree in data that only concerns the US (and even here 1998-2002 is still substantially warmer than 1930-1934). Big wow. The impression some have tried to give that the science has suddenly shifted sixty-odd years in its assessment of the warmest period is deeply misleading.

And of course in the global mean the warming trend is even more pronounced. It is not a bogus claim.

I'm not denying the planet is warming up. I'm skeptical as to the current dogmatic claims that:

a) we are causing it all due to CO2 emissions (even the IPCC report of 2007 says that global land use change is also a major contributor to higher temps)

b) that it's all doom and gloom, the world will be unlivable ala Lovelock et al. That's nonsence. The planet is a huge buffer and recovers quickly. Even the KT impact was recovered from quickly.

c) that it is fixable. Even if we can reduce our CO2 and remove what we can from the atmosphere what is the economic and resource costs to do it? IN an era of oil decline do we have the moral right to use that resource on AGW? Who in turn is to be without home heating fuel? How many will die because we divert oil to solving AGW. Remember The Law of Unintentional Consequences rules. There is no way anyone can predict what can possibly go wrong.

d) the absolute media hype and misrepresentation (the Gorites). This includes predictions that are presented as "will happen" when they are nothing of the sort (some predictions even viotate physical laws). Whenever any published study does not support the dogma it's not mentioned in fear of shaking the State of Fear the media requires to keep ratings.

e) climate science is not like other sciences. You can't very well stop the Gulf Stream from happening as an experiment to see what happens. We can't roll back the clock, change parameters, and see what happens. Climate is governed by Chaos Theory, is influenced by the Butterfly Effect, and we have just scratch the surface in our understanding of how it all works. This makes ANY preditions of future climate changes HIGHLY SUSPECT.

f) finally, AGW is too far in the future. Even Simmons is now saying PO is the bigger threat. That sentement will expand as that threat becomes more popular.

Richard Wakefield
London, Ont.

No one is ahead of their time, just the rest of humanity is slow to catch on.

Sorry jrwakefield, I just don't have time to engage with this nonsense. You said "The hottest times on record is still the 1930s" - how is that not denying that the planet is warming up?

This seems like classic contrarianism - not actually putting forward a consistent position but simply disagreeing with everything the scientific community reach agreement on, then reluctantly backing down to the next point of uncertainty and denialism when the evidence becomes overwhelming. Why?

I'll just have to refer you here to find some decent responses to your various inconsistent points. But I agree that Peak Oil is just as critical as Climate Change (see my first post here that started all this) - they are really just two sides of the same problem. Solving one while making the other worse is no use.

I thought my point list made it clear on my position. The fact is the 1930s at least TIES with the 1990 values. Undisputed. We have to wait and see what the future numbers are.

Bottom line is I'm not fixated on a postion. I will let the evidence show me what is happening. If we go into years of cooling what would your position be? It can't happen you say? That's not science, that's dogma.

And I'm not alone, I have a VERY long list of scientists who reject AGW, including some formerly from the IPCC. And no, they are not funded by Big Oil.

Richard Wakefield

Richard,

You need to recheck your facts here. The thirties were significantly cooler than the ninties. you may be confusing the US record with the global record.

You are very likely being influenced by people who wish to deceive you. Hope this helps you to recognize the deception and be more careful in the future. There's a sucker born every minute, but there are 251 other people born every minute, so you don't have to be the one.

Chris

So everyone on WorldClimateReport is out to deliberately decieve people???? People like Richard Lindzen who utterly reject AGw on SCIENTIFIC grounds (and no he is NOT funded in any way by Big Oil, I have a letter from him categorically denying the lies on the Internet)

No, it's REFEREED PAPERS that contradict the dogma of AGW. I'm QUITE capable of understanding the issues (I thought myself geology and published a paper in 1988 solving a small geological enigma). And yes, it was the US numbers, never said it wasn't. The fact is the hottest years was forced to be changed because it was wrong. That is a fact.

This graph you posted it telling indeed. Why did temps start to rise between 1890 and 1940 before there was significan CO2 emissions? Why did it level off just as we started to pump CO2 in huge quantities?

Richard Wakefield
London, Ont.

The more complex society becomes, the more myth and fantasy people invent to explain it.

it's REFEREED PAPERS that contradict the dogma of AGW.

What is a "refereed" paper? Do you mean a "peer reviewed" paper?

I thought myself geology and published a paper in 1988 solving a small geological enigma

Did you teach yourself geology, or just think about it? Could we have a reference to this paper and where it was published, so we can see if your science is as good as your spelling?

Why did temps start to rise between 1890 and 1940 before there was significan CO2 emissions?

What is a level of "significant" emissions according to Mr Wakefield? Are you aware of the existence of the steam engine buring coal, ships burning coal or diesel, etc, before 1940? Are you aware that the industrial age using fossil fuels began in the late 18th century, not only after 1940? Did you perhaps imagine that the Fuhrer's tanks were powered by solar cells, and the Royal Navy's dreadnaughts ran on sherbert?

Why did it level off just as we started to pump CO2 in huge quantities?

Because things other than carbon dioxide affect the global climate. Most significantly, when you burn coal and oil, there are aerosols, particulate emissions - basically, soot. While CO2 has a warming effect, soot has a cooling effect.

However, soot drops out of the air after a bit, while the CO2 remains, so that the warming effect of the CO2 comes forward. In addition, in December 1952 there came to London the Great Smog. London had always been well-known for its "pea soup" fogs, but this time it killed 4,000 people in four days, with another 8,000 dying in the following weeks and months. This led to the Clean Air Act of 1956, and over time the pea soup fogs went away.

People having decided that choking to death on soot was not a desireable outcome, this sort of legislation spread, reducing the amount of particulate emissions from the burning of fossil fuels. As the aerosols diminished, so did their cooling effect.

And that's why you see the temperature decline or plateau in the 1945-75 period. Soot.

We could bring the soot back if you like, there's that minor problem of choking to death on the stuff, but aside from that it should slow global warming a little bit - at least until the soot drops out of the air and leaves the CO2 behind to warm us.

Richard,

How it is that you are repeatedly making false claims? You state that the rate of increase of sea level rise has been constant when it is not. You claim that the thirties were as warm as the nineties when they were not. Either you are making these claims in good faith but have been duped, or you are deliberately trying to mislead people. Based on some of your thoughtful other comments, I am guessing that you are being influenced by disreputable and malign people who are working in concert to attempt to sow doubt and falsehood. These people exist and so seeing their propaganda being repeated from time to time by otherwise thoughtful people is not unexpected. But, twice now, I have shown you a blatant error in a statement of yours and I do not see you applying skepticism to your false sources, but rather defending them. I urge you to consider how you approach factual information in this topic and start looking hard at the intentions of those you frequently cite.

Chris

You state that the rate of increase of sea level rise has been constant when it is not.

According to Tide and Currents, Australia's National Tidal Facility and the IPCC the RATE OF SEA LEVEL RISE HAS NOT CHANGED

Please post a reference that disputes these respectable science institutions and their measurements.

Here are mine that shows it is not changing:
http://www.bom.gov.au/ntc/IDO60023/IDO60023.2005.pdf Note pages 23-24. THE RATE IS FLAT since 1972 in the Pacific.

and http://tidesandcurrents.noaa.gov/sltrends/sltrends_global_station.shtml?.... This is Sydney Australia. I picked this because it's a stable craton. But you can check any on this site. THE RATE IS FLAT!!!

I am guessing that you are being influenced by disreputable and malign people who are working in concert to attempt to sow doubt and falsehood.

Oh, I see. I'm incapable of looking at evidence and making my own judgement. I'm entirely swayed by what devious people try to put over on me. Get real. I'm a reasonably intellenegent individual capable of reading science papers and understanding them. Don't be insulting to me. My IQ is bigger than 50. I figured out Peak Oil 20 years ago on my own, so I can figure out AGW too.

So you have made an accusation of deceit. Maybe you can show me evidence of this at WWW.WorldClimateReport.com or the 60 climate scientists who wrote to our Prime Minister. http://www.cbc.ca/news/background/harper_conservatives/pdf/lettertoharpe.... What is their motive for deception? Don't speculate, provide evidence. If you can't do that then your guess is wrong.

I could challenge back and say all those who take AGW hook line and sinker are the one's being decieved (Gore's film has all kinds of deception and inaccuracies he knows about), and say that the dogma of human causation of climate change is a communist plot to bring down the world's capitalist systems. But I'd have to provide evidence of that wouldn't I?

So it's OK to challenge peak oil theory, challenge the consequences of oil depletion, but it's not OK to challenge AGW? Sounds like a double standard to me.

Richard,

We have come full circle. You now deny that the rate of sea level rise has changed when you had previously conceded that it has, and you do so by referring to incomplete evidence. This is similar to your false statements about temperature trends. This is not arguing in good faith. Others have already said they don't have time for you. I took you at your word that you would be persuaded if you knew the rate of sea level rise had changed. It has. Your statements just don't seem to be truthful, so I'll not waste any more time on this.

Chris

What????? I've always maintained that the measurements show the rate HAS NOT CHANGED. I posted references showing just that. IT HAS NOT CHANGED. How can you look at these graphs and say the rate has changed when the lines are straight????

This will come up again...

Interesting that this author does not understand what chaos theory means. Climate is an execellent example of a chaotic system -- many input variables, where small initial values can have huge changes in behaviour. Of which we still do not understand how it all works.

So your reference is a tad suspect, but I'll read more. Will you read World Climate Report? Or are you so fixated on AGW dogma that contrary evidence is just a priori wrong?

Even the KT impact was recovered from quickly

Quickly? How many thousands of years are we talking? Certainly not quickly enough for the dinosaurs or any other species that was wiped out.

Some dinos made it. Birds. The 75% of species wipped out with the KT impact is just part of evolution. It's happened before, is happening now. Just we are the agents of the current exctinction.

There is no know precise time that the earth recovered, as the next layers of sediment after the IR layer has life in it again.

If you read what happened at Krakatoa for example, you will see that within just a few years life returned. Within 10 years it had inhabitants again. Now it's a lush tropical forest.

Of course, time frames are relative. We look at our very short lives and expect that what we see is what is normal. We expect things to happen within our own time frames of existance. But that's not how Nature works. Assuming AGW is true, and irreversable, then the buffering effects of the earth may indeed be 100 years or more to recover from our mess. I suspect that other messes we have created will take far far longer (such as replacing all the farm land with normal ecosystems). But eventually, Nature will have the last word on us and our messes.

Shaunus4,

Big international organizations can't be trusted when there's a big political motivation to just parrot the party line. Look at the International Energy Agency that still has to pretend that the Persian Gulf oil producers are honest in their published official oil reserves.

according to the World Health Organisation 150,000 people are dying each year as a consequence of climate change ALREADY.

Actually they say "may be dying". At best it is a guess.

To put this number in some context, 4.84 million people died of smoking in 2000. AIDs around 3 million, road accidents about 1.2 million (2001).

While I am fully onboard with the science in the IPCC reports, there is a lot of commentary about them that is overhyping the impacts to the point of hysteria.

The context is appropriate, thanks, although it is also worth remembering that the climate change figure is a snapshot of a rapidly rising problem which we know has already got worse since 2000, and will get much worse in the near-future regardless of the choices people make (not to mention getting much, much worse given 'Business As Usual').

Due scientific process in the giving of the results of analysis does not make the results of that analysis "at best a guess". Please justify this comment.

It is easy to estimate deaths based on specific weather events, but as we know it is very hard to pin these to climate change. I admit I haven't seen the WHO report, still looking, but it can only be a guess. The science is simply not able to be precise. Call it an educated guess if you prefer.

Regarding trends in deaths due to weather events:

I would expect there to be more deaths due to extreme weather simply because the population density where extreme events happen is much higher.

Talking about even millions of deaths is unjustified and alarmist.

ain't modern medicine, sanitation treatment and rapid projection of aids having more to do with the decline than the severity of the climate related events?

so long as the pot has not been heating up abruptly and enough frogs are dead in the water, any frog calls to jump is an alarmist.

ain't modern medicine, sanitation treatment and rapid projection of aids having more to do with the decline than the severity of the climate related events?

And that is EXACTLY why the WHO prediction cannot be taken at face value. There are just too many factors at play.

Well isn't that graph revealing!! Even though the population has doubled since the 1920s, weather related deaths has gone WAY down and falling. So that graph just showed the WHO wrong.

BTW, a study reviewed in WCR showed that in the past 5000 years storm numbers and intensity in Europe has not changed. There have not been more storms lately due to climate change.

Also, the death toll from the cyclone in Bangladesh was far far fewer than the all time high death toll in the 1960s at 500,000. Rising death due to climate change is not panning out. Once death starts to rise from oil decline, how will the two affects be separated?

Hi BobCousins - what's the source for this graph please? And could you explain the difference between deaths per year and death rates per year? I must be missing something there.

In terms of the results of any scientific analysis just being an educated guess, well, if you insist, but it seems a very strange (not to say misleading) use of language to me. I might guess at the numbers of molecules in the Atlantic Ocean, but I think there would be a fundamental difference between that and the results of an analysis of the problem, despite the fact that the analysis would be equally unable to give a perfectly accurate and precise figure.

Note that this is weather related events.

I chased down the source of the "150,000" figure and it comes from a study by Dr. Diarmid Campbell-Lendrum. He considered deaths from floods, diarrhea, malaria and malnutrition. For example "he looked at a study that charted hospital admissions for diarrheal diseases in Lima, Peru, between 1993 and 1998. Every increase of one degree Celsius in average temperature produced an 8 per cent increase in hospital admissions".

Om malaria part:
Not all scientists were convinced by the study, especially by the link it draws between warming and malaria.

"It is naive to predict the effects of 'global warming' on malaria on the mere basis of temperature," Paul Reiter, a professor at Paris's Pasteur Institute, said in a statement."

From this Campbell-Lendrum estimates death rates for each degree of warming. Extrapolating like this one from small bit of data is what I call guessing.

Interesting what you've dug up there - thanks for that. Presumably the numbers would have been higher than 150,000 if Dr. Diarmid Campbell-Lendrum had considered all the impacts of climate change, and not just temperature change. Not to mention that the WHO report clearly states that the figure is based only on a subset of the possible health impacts, and that these impacts are only likely to increase after 2000.

But I still consider this figure somewhat more rigourous than my own somewhat higher educated guess as to the number of fatalities currently caused by climate change each year.

Re: the weather figures you produced, it is a classic cherry-pick. If you look at the source of the data here (under the heading "Natural Disasters Trends: World 1900 - 2006") you will see that the data in your chart is far from representative of the overall picture, which clearly shows that the overall trend for natural disasters is overwhelmingly an increase, and hence that the decrease in fatalities absolutely cannot be put down to a decrease in extreme weather events. Presumably our purely evidence-based friend jrwakefield will find this data equally revealing...

Indur M. Goklany of the Commons blog, who produced the chart, presumably also saw this data and knew full well that the answer to his question "why, if the globe is warming, aren't matters getting worse?" is that "they are". I recommend you ask him why he chose to mislead his readers.

Presumably our purely evidence-based friend jrwakefield will find this data equally revealing...

Absolutely. It's absolutely meaningless. Just because there APPEARS to be a correlation does not mean there IS a correlation. Such entrapments happen all the time. Without control groups, without experimentation, there is no way one can make the conclution that all those deaths were a direct result of warming.

First, was the warming in those areas actually happening? Climate Change theory does not mean that the entire world's temp is increasing. The upper temps may not increase at all, but the lower temps do, leading to more moderate temps which gives a higher average.

To provide any statistical relationship one would have to specifically plot the temperature, and its resulting affects, directly with deaths. Was that done in this study? I suspect not. VERY difficult to do.

Second, how many people are living LONGER due to climate change. Don't tell me none, because if a study is done I'll bet there are people who are benifiting and living longer.

And as for all those deaths from current storms, just a perfect example of jumping the gun and imposing a 1:1 ratio of deaths to climate change where none exists. In the 1960's 500,000 people in Bangladesh died from one cyclone. The 10,000 from this one is a huge change for the better. We have better warning systems, better evacuation plans, all change how many will be killed from any one storm.

I'm not sure how best to interpret the data, the number of reported disasters is up, but trends of fatalities are down.
The relations are obviously very complex, therefore I still maintain that the estimate is little better than a guess.

While GW is of great potential concern, actual and predicted impacts seem to remarkably low.

The elephant in the room is really the huge population increase in coastal and low lying areas that are already prone to risk. You can also throw in drought prone areas. Humans have rapidly filled lots of sub-optimal areas, which even from the record of the past 10,000 years, are subject to damaging climate variation.

It's true that AGW over the next 100 years presents a risk, but we have built a precarious systems that is at risk from any climate change, whether natural or anthropogenic.

Dunno where you got that chart from, but it's missing several million deaths. Considering just hurricanes in Bangladesh, in 1970 there were 300,000-500,000 dead, and in 1991 there were , 138,000 dead

Or does your chart just count elderly Westerners dying from heatstroke as "extreme weather event" casualties?

No, you have misread the graph! It shows average deaths per year over a decade. The underlying data has a high yearly variation.

You can see year by year data here http://www.em-dat.net/disasters/img/Natural/kilyr1.pdf
The trend is the same.

I admit that I would expect the trend to be up, so I find this rather puzzling.

No-one seems to have pointed out the revious attempt at limiting production, OPEC and their production quotas, begun in the early 1980s.

The quotas were to be based on reserves. The idea was that quotas would give price stability, and ensure that all the OPEC countries used up the last of their oil at about the same time. Now, their intention was simply financial, with no consideration of peak oil or climate change, but it's similar to what you're proposing, in that it was an international agreement among oil exporters to limit those exports.

And what do we find with the history of OPEC? We find that as soon as they'd agreed to limit production to proportional with their reserves, their stated reserves jumped by hundreds of billions of barrels. And quite a few countries - tempted by high prices - regularly produced over their quotas.

What was lacking from the OPEC agreement was what we have in arms reduction treaties - international inspectors for verification, and provisions for action on violation. OPEC ought to have had some international body which would determine and verify the reserves, and some mechanism for penalties for overproduction, just as in arms control we have international inspection teams, and provision for sanctions, and so on.

So OPEC's production quotas shows us an attempt at restricting oil consumption solely by a supply-side approach.

What was also missing from OPEC's quotas was bringing the buyers into it. We need to look at both supply and demand. The OPEC quotas demonstrated that there's no sense agreeing to limit production if others won't limit their consumption, because the temptation will always be there for the producers to violate the agreement. If supply is deliberately limited to 100 units, and the demand is 101 units, this drives the price up, and then one of the suppliers is definitely going to break.

You're quite right that the supply side has been largely ignored. But honestly, if you're only going to look at supply or demand, it's better to look at demand. It's best of it to deal with both supply and demand, but if you really must focus on just one, focus on demand.

Lastly, I'd note that I think demand is most focused on because it can be looked at through lots of levels. As an individual I can change my demand for stuff; as a community or company I can change my demand; as a country I can work to change our demand. But I can only change supply at an international level, by treaty. Focusing on demand lets me do something whether I'm just some average Joe, a town councilman, a CEO, an MP, or diplomat. But unless I'm a Prime Minister there's really nothing I can do about supply. So demand has got the focus because it offers almost anybody the chance for real action. Whether it's effective action or not is of course another question.

I think your history of OPEC is a little off. OPEC has in the past managed to reduce supply in order to maintain a price level. The quota system is not perfect, but still can be effective.

But I can only change supply at an international level, by treaty

For oil importers, which most countries are, that is obviously not true. A country could easily place a limit on imports. They already have customs and police to provide inspection and enforcement.

Speaking as an American taxpayer rather than getting taxed to pay Venezuela or Ecuador not to produce oil I'd rather get taxed to:

1) Convert the heating of all government buildings to geothermal heat pumps.

2) Better insulate all government buildings.

3) Convert all government vehicles to diesel and/or hybrid technology.

4) Design much more fuel efficient designs for military aircraft and ships and vehicles.

5) Fund more research into photovoltaics and nuclear energy.
