RSS: Warmest January Ever

Remember all those big headlines about how cold is was in January? Turns out that was mostly in the U.S.

Globally, last month was the warmest January ever as measured by RSS's satellite, and and the 4th warmest month in their records -- the warmest since May 1998.

Their number for the temperature anomaly (as measured by their satellite), was +0.640°C.

RSS is probably the least controversial of the four temperature data series, and the measurement is purely by satellite, so it will be interesting to see how this result is denied, dismissed, or ignored (beyond the involvement of an El Nino -- in fact, a good question is: why are recent El Ninos so large?).
