Excerpt:
Confirming what many of us have already noted from the anecdotal evidence coming in of a much cooler than normal May, such as late spring snows as far south as Arizona, extended skiing in Colorado, and delays in snow cover melting in many parts of the northern hemisphere, the University of Alabama, Huntsville (UAH) published their satellite derived Advanced Microwave Sounder Unit data set of the Lower Troposphere for May 2008.
It is significantly colder globally, colder even than the significant drop to -0.046øC seen in January 2008. The global deltaT from April to May 2008 was -.195øC
UAH
2008 1 -0.046
2008 2 0.020
2008 3 0.094
2008 4 0.015
2008 5 -0.180
Compared to the May 2007 value of 0.199øC we find a 12 month deltaT is -.379øC.
But even more impressive is the change since the last big peak in global temperature in January 2007 at 0.594øC, giving a 16 month ?T of -0.774øC which is equal in magnitude to the generally agreed upon "global warming signal" of the last 100 years.
I'm betting that RSS (expected soon) will also be below the zero anomaly line, since it tends to agree well with UAH. HadCRUT will likely show a significant drop, I'm going to make a SWAG and say it will end up around 0.05 to -0.15øC. GISS; I'm not going to try a SWAG, as it could be anything.
