Last week I posted the University of Alabama, Huntsville (UAH) Microwave Sounder Unit (MSU) global temperature anomaly data for February 2008 with a note that it showed only a marginal increase from January 2008 data, and remained near zero.
First here is UAH satellite derived temperature anomaly. For February 2008, 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.
Next we have the RSS satellite derived temperature anomaly. It also shows a slight rebound from the -0.080°C value of January 2008 to 0.007°C for a slight change (∆T) of .0.073°C upwards. The anomaly remains near zero as does the UAH data.
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 starting 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 (GISS, HadCRUT) as soon as they are available.
