Last month I posted the University of Alabama, Huntsville (UAH) Microwave Sounder Unit (MSU) data for January 2008 with a note that it showed a sharp drop from January 2007 data.
The February data from UAH is out. You can see it the raw data yourself here
It shows a slight rebound from the -0.046°C value of January 2008 to 0.016°C for a slight change (∆T) of .062°C upwards.
It appears the La Niña in the Pacific and the solar minimum are continuing to affect temperatures globally, resulting in this cooler period for the last 13 months in January 2007.
Below: A plot of sunspots showing our current position in the solar minimum. Note the uncertainty for the two projections of the next cycle 24.
I’ll plot the other metrics (RSS, GISS, HadCRUT) as soon as they are available. I expect the RSS data to be published soon, perhaps in the next day or two.
