The Divergence between Surface and Lower Troposphere Global Temperature Datasets and its Implications

Guest Post by Bob Tisdale I include a graph in my monthly global surface temperature and lower troposphere temperature anomaly updates that compares the average of the global surface land+ocean temperature anomaly products (from GISS, NCEI and UKMO) to the average of the global lower troposphere temperature anomaly products (from RSS and UAH).  (See Figure…
