Last month, NASA reported it was the hottest January-September on record. That followed a terrific analysis, “July 2010 — What Global Warming Looks Like,” which noted that 2010 is “likely” to be warmest year on record.
This month continues the trend of 2010 outpacing previous years, according to NASA:
It now seems pretty certain 2010 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 October for NASA, though it was third warmest. 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.” That said, as you can see, the October anomaly (deviation from the 1951-1980 average) was higher than September, in spite of the La Niña.

Look how warm the Arctic temperatures are. If Siberia was not having a cold year, we would really be way up there.
