Sometimes it's as easy as watching the trends. EIA, IEA & Colin Campbell have been the most prolific suppliers of annual outlooks wrt Peak Oil. EIA, IEA & the optimists have been revising their targets downward over the years by an avg of 3-mbd/annum.

The Peaksters have been upward revising by just under 2-mbd/annum.

It is relatively easy to revise up due to availability of bottom-up flow analysis on the short and medium term.

The long term targets have been based, disturbingly, on demand projections tied to Real GDP Growth. These 2020 to 2030 targets are also dependent on sufficient resource (URR). Using Hubbert type analysis, URR's in the 3 or 4 Trillion barrel magnitude helped justify those targets from an geologic viewpoint. What is lacking unfortunately is sound basis for supply from each country associated with the targets and timelines.

The first to lash out was Saudi Arabia at the CSIS Conference in 2004. It called the IEA & EIA targets for itself absurd. But they have been a voice in the wilderness in their pleas for sanity and due diligence on the part of stakeholders and decision makers. It did make some difference. TrendLines chastised EIA and published an "Aramco-modified EIA projection to draw light and scrutiny. The 2005 EIA model was trimmed 10mbd accordingly.

If awareness of the Peak Oil phenom and consequences are to become topical, it is necessary to challenge the 2020 to 2030 targets that give sighs of relief to peak watchers.

At this point, it is only the the upward revisions (as shown below) that have momentum and gain the attention of analysts and pundits. At TrendLines, we are entering the third year of posting our tracking updates of the ASPO/Campbell record. Colin's Peak Rate has moved between 64-mbd to 89-mbd. The Peak Date has ranged from 1995 to 2012. Exhaustion has been extended from 2060 to 2100.

Optimism is relatively easy when the magnitude of upward revisions is incrementally increasing ... not decreasing:

Thanks very much for these graphs!

What they show is that Cambell's predictions for the maximum rate of Oil production is greater than what is needed to stablize the global climate temperature to a rise of 2 degrees or less.

This is generally regarded as requiring a 60% decrease in in CO2 output from 1990's levels, which would be 24 MPD by 2050.

In other words, we have to do better than Peak Oil would allow us. So it's not a matter of "if" Peak Oil will occur, it is matter of how can we do better than Peak Oil.

This is generally regarded as requiring a 60% decrease in in CO2 output from 1990's levels, which would be 24 MPD by 2050.

Ah but oil is a pretty small amount of total anthropogenic CO2 emissions. See this graph from the James Hansen article:

That shows the cumulative atmospheric concentration of CO2 from each fuel with a peak oil/gas very roughly around 2030. There just isn't enough oil/gas to get to past 400ppmv. Climate change is all about the coal and non-conventional oils in my mind. In fact I'm not convinced non-conventional oils are ever going to economically scale up so maybe it's really just about the coal.

Thanks very much! This is most informative.

This also seems to illustrate "Peak Coal" at 2050.

I am not sure what constitutes 'scale' on non conventional oil, in your mind, but I am fairly certain Canada will reach 5m b/d of Tar Sands oil, and Venezuela has equivalent capacity of its heavy oil *however* greater infrastructural challenges and political issues.

Whether Canada could get to 10 m b/d I don't know.

I would think, if oil was say, $120/bl, that 5-10m b/d of Coal-to-Oil and NGL would be quite likely.

In both cases, the GW consequences are pretty frightening. I believe the burning of a barrel of tar sands oil has, end-to-end, 3 times the CO2 emissions of a barrel of conventional oil.

Agree with your tack that coal is the primary GW issue (along with deforestation, non CO2 greenhouse gases, etc.).
