The modus operandi of alarmists is to stake out all possible positions – which guarantees that no matter what happens they can attempt to claim victory. Sometimes it backfires though.
Hansen claims that his 1988 forecasts were pretty close, because CO2 emissions have been much lower than scenario A. This is complete nonsense on all counts, as John Cook inadvertently points out.
“I got that chart from John Cook’s indispensable Skeptical Science site, which is a great depot for scientific arguments about climate change (if you think you’ve come up with a novel reason why global warming is all hokum, search Cook’s site first).”
BWAHAHAHAHAHAHA!!!
“if you think you’ve come up with a novel reason why global warming is all hokum, search Cook’s site first”
..because the stuff on there is so wrong, Cook himself shows why AGW is hokum.
I think that recent dip was caused by the recession.
If global mean temps take a prolonged dip then it’s going to be great fun listening to the evangelical Cook spin his way through. Aerosols, mount Pinatubo, blah, blah, blah…………….. Look to the cosmic | clouds

“The ROUGH consensus among climatologists is that every doubling of CO2 will warm the Earth around 3°C. Yes, that figure has been largely derived from computer modeling, but there are good external reasons to believe those models.”
What’s a “rough” consensus? Why no mention of water vapor, which is the real culprit? CO2 is supposed to just be a forcing. It’s not possible to double CO2 by 2100 at the present rate. It would take 2 centuries.
Have you read this?
Past atmospheric co2 levels have been much higher than even quadrupling. 😉 No runaway Venus style warming. AGW is a pack of lies.
Yup, read that yesterday Jimbo, guess it’s going to take a couple of cooler more years before they come to their senses???
