John Christy has provided us with the latest information on the global (GL), northern hemisphere (NH), southern hemisphere (SH) and tropical (Trpcs) values. For the last three months they are (in terms of anomaly)
GL NH SH Trpcs
Jan -0.05 -0.11 0.02 -0.21
Feb 0.02 0.25 -0.21 -0.33
Mar 0.09 0.43 -0.25 -0.49
The positive value in the northern hemisphere is dominated by the land areas. This large difference between the hemispheres (and the large negative values in the tropics) needs explanation, as none of the global models have predicted such a behavior that I am aware of.
Their analysis supports the findings reported at Watts Up with That from the RSS MSU analysis group.
