Actually, going from 3 to 9 would be an increase of 200%.

Yeah, I should have written 'an increase to 300% from the original base figure' but figured that anyone of normal intelligence would be able to follow, so did not bother re-writing.

I've always wondered why it is that going from 3% to 9% wouldn't be an increase of 6% (9-3=6). It seems that when you quote the 300% figure, you're talking about the percent that a percent is changing, but that ought to be a per-decimil rather than per-cent, but people never agree with me on that.

That's where percentage points come in.

surely 3*3 = 9 = 300%

I think I understand your lack of understanding of AGW a bit better now....

Of course, AGW stopped around the turn of the millenium. http://www.yorkshirepost.co.uk/opinion?articleid=3975938

When your appeal to authority is an article by a British ex-government minister from the Thatcher era, you must be getting desperate.

No, but it annoys the green nazi's, which is the important thing. Will global warming resume again or not? If not there will be some red faces around.

You're approaching the league of jbunt, that of nincompoop. This last March was the warmest on record over world land surfaces and "second warmest overall worldwide."

Ta.

Check this out, genius:

Sea Ice Index

For something more you denialists' cherry picker style:

Last month was the warmest March on record over land surfaces of the world and the second warmest overall worldwide.

And here's the clincher. Pay special attention top Fig. 5. Everything and anything else you know about sea ice pales in comparison. It is *the* thing you need to understand.

Multi-year ice almost gone.

Parting shots: What do you *not* understand about trends?

What do you *not* understand about La Nina?

Who pays you to spout this crap when even G. Dumbya Bush admits AGW is real and lives in one of the Greenest homes you could hope to find, eh?

Now, crawl back to Exxon and tell them to kiss my arse.

Cheers

The loss of sea ice last summer was funny, since 2007 was only the 8th warmest year on record. There were 7 warmer years but without the the massive loss of Summer ice cover. Some odd factor was at work. despite increasing emissions the annual temperature trend seems to have stabalised. Whether it will stay so remains to be seen.

What's funny is using inaccurate data to draw inaccurate conclusions. 2007 was the 8th warmest year on record - in the US. Worldwide it was the equal second warmest year on record. And more importantly, when analyzed by region, warming was particularly strong in the Artic:

http://www.giss.nasa.gov/research/news/20080116/

Climatologists at the NASA Goddard Institute for Space Studies (GISS) in New York City have found that 2007 tied with 1998 for Earth's second warmest year in a century.
[...]
The greatest warming in 2007 occurred in the Arctic, and neighboring high latitude regions. Global warming has a larger affect in polar areas, as the loss of snow and ice leads to more open water, which absorbs more sunlight and warmth. Snow and ice reflect sunlight; when they disappear, so too does their ability to deflect warming rays. The large Arctic warm anomaly of 2007 is consistent with observations of record low geographic extent of Arctic sea ice in September 2007

right, which is why March was the warmest worldwide on record...

between not being able to do the math, trusting sources who are not experts in the field and believing in mythical creatures called Green Nazis - I'm very not surprised that you don't understand AGW

Yes, I expressed it in terms of 300% to try to retain the original articles format, where they obviously got confused about the rise up to 9% burn-up and said 900%.
I wrote rather sloppily though and should have said that the new burn up figure of 9% was 300% of the original figure, not an increase of 300% as I said.
It seems to have upset the pedants. although since I gave the 3% and 9% figures the meaning should have been perfectly clear.

9 fold would be 300% of the original, but an increase of 300% would be 100% + 300%, 400%, so 4*3=12

Its just games with the word 'increase'
