Global Cooling — The Evidence Mounts

Over the past year, front page news stories have provided ample anecdotal evidence that makes it mighty hard to get worked up about global warming. Now, hard empirical data further supports that skepticism.

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 really, really, REALLY hope that some media outlet somewhere will provide at least a little coverage of next week’s International Conference on Climate Change in New York City. This data will likely occupy a prominent role in the proceedings.

[NOTE: Anthony Watts, author of the original article which reported the data, objects to the wording in the Daily Tech report quoted above:

There has been no “erasure”. This is an anomaly with a large magnitude, and it coincides with other anecdotal weather evidence. It is curious, it is unusual, but it does not “erase” anything.

Fair enough. But even as an unusual anomaly, it’s still newsworthy.
