2010 Still Hottest Year on Satellite Record So Far: NASA

And the heat keeps on coming. The records continue to be met or broken, and what was last month announced to be the hottest January-August period in the global temperature record has moved on to become the hottest January-September ever measured. But don't take it from me -- take it from NASA. NASA's latest data shows us to be on track to experience one of the hottest years ever recorded. Climate Progress parses that data:

It seems all but certain we will outpace 1998, which currently ties for fourth hottest year in the NASA dataset (though it is technically described by NASA folks as tied for the second hottest year with 2005 and 2007).

Outpacing 2005, the hottest year on record, will be closer. In NASA's surface-based dataset, we are unlikely to set the record monthly temperatures for the rest of this year; last month wasn't close to the hottest September for NASA. We have entered a moderate to strong La Niña, which NOAA says is "expected to last at least through the Northern Hemisphere winter 2010-11."

But even the La Nina, which some were certain would have a wide-ranging cooling effect, hasn't brought down global temperatures -- the satellite records show that it was hotter than ever in the troposhpere. Some satellites showed that September was the hottest on record.

It all adds up to more hard-to-deny evidence for continued global climate change. And it will be all the more striking if 2010 ends up being the hottest month ever record. As Joe Romm concludes at CP: "Before this month, I thought 2010 might not be the hottest year in the satellite record, but now it seems like there is a good chance it will."
