The global-average lower tropospheric temperature anomaly soared to +0.72 deg. C in January, 2010. This is the warmest January in the 32-year satellite-based data record.
The tropics and Northern and Southern Hemispheres were all well above normal, especially the tropics where El Nino conditions persist. Note the global-average warmth is approaching the warmth reached during the 1997-98 El Nino, which peaked in February of 1998.
This record warmth will seem strange to those who have experienced an unusually cold winter. While I have not checked into this, my first guess is that the atmospheric general circulation this winter has become unusually land-locked, allowing cold air masses to intensify over the major Northern Hemispheric land masses more than usual. Note this ALSO means that not as much cold air is flowing over and cooling the ocean surface compared to normal. Nevertheless, we will double check our calculations to make sure we have not make some sort of Y2.01K error (insert smiley). I will also check the AMSR-E sea surface temperatures, which have also been running unusually warm.
Of course this has nothing to do with global warming, nothing at all
