Talking about the weather - satellite temperature measurement

Newly released data showed that May 2008 was cold cold cold! From Watts Up With That:

UAH: Global Temperature Dives in May
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, (here and here), 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 -0.046°C seen in January 2008.

The global ∆T from April to May 2008 was -.195°C

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 0.199°C we find a 12 month ∆T is -.379°C.

But even more impressive is the change since the last big peak in global temperature in January 2007 at 0.594°C, giving a 16 month ∆T of -0.774°C which is equal in magnitude to the generally agreed upon 'global warming signal' of the last 100 years.

The picture tells a thousand words:
