But I bet you're wrong on the direction of the change so far this year...
o more than anecdotal evidence, to be sure. But now, that evidence has been supplanted by hard scientific fact. All four major global temperature tracking outlets (Hadley, NASA's GISS, UAH, RSS) have released updated data. All show that over the past year, global temperatures have dropped precipitously.
A compiled list of all the sources can be seen here. The total amount of cooling ranges from 0.65C up to 0.75C -- a value large enough to wipe out nearly all the warming recorded over the past 100 years. All in one year's time. For all four sources, it's the single fastest temperature change ever recorded, either up or down.
I am waiting for an explanation from those of you that link carbon dioxide production to global temperatures. Not only have we produced more since 1998, the hottest year on record... we've dropped in temperature. I think your models do not mean what you think they mean.
