Rich2 - I won't go through all of that but as a start the 1990 report by the IPCC forecast minimum temperature increased of 0.2 degree C for each decade. That is a total of 0.4 degrees minimum increase which should have occured by now.. the actual result was, charitably, something like a 0.15 degrees increase. You'll have real trouble finding the report as the IPCC doesn't have it on its site anymore. Proved to be too much of an embarrassment. the panel also forecast big temperature increases in its 2000 report but basically since then nothing has happened - temperatures have bounced around a bit.. up in 2010 but down in 2008-09 and likely to be down this year due to la nina. Slightly down overall since the 2000 report perhaps but its arguable..

Global warmers have been reduced to arguing that really the warming is there, we just can't see it due to other factors.. right!

the 2007 report was more of the same with still nothing happening. Warming patterns? Nope, they also don't conform. Hunt around and you'll see what I mean..

Nothing is working out as the IPCC forecast..

Curmudgeon,

I found the report in about 3 seconds. Try keying in "IPCC 1990 report" into Google.

I think you should provide the table as you have made the comment.

If you are correct then it would be interesting to know it.

Better still, try here:

When a supposed 'science writer' can't scroll down a site but instead comes out with;

"You'll have real trouble finding the report as the IPCC doesn't have it on its site anymore. Proved to be too much of an embarrassment."

one can't help but query the writer's cognition skills.

Curmudgeon, you only see/believe what you want to see/believe - regardless of the truth.

Yep, cognitive dissonance and confirmation bias.

Anti-green
In other words, George W Bush and the Republican Party are climate change activists. Excellent!

Who argues with deniers anymore? These political, economic and religious fundamentalists are a lost cause. When the empirical evidence indicates otherwise, when climate scientists recant and my instincts are assuaged, I'll reassess. Otherwise...

The dogs may bark but the caravan moves on.

The imbecilic yapping of deniers leaves me unmoved.

Rich2 & Bonmot

What Curmudgeon posted is essentially correct. They certainly indicated in AR3 in 2001 that temperatures would be expected to increase in the first 3 decades on this century at a rate of approx. 2C per century. See for example:

http://rankexploits.com/musings/2008/ipcc-projections-overpredict-recent-warming/

For the last 10 years global temperatures have been flat; varying from slightly positive for GISSTEMP to slightly negative for HADCRUT (for example). See
