Climate Change Impacts Explained in Real Time

GISS Surface Temperature Analysis

NASA Goddard Institute for Space Studies

NASA's "Global Maps from GHCN v3 Data" allow users to select parameters to create a surface temperature anomaly or trend map. 

Graphs and tables are updated around the middle of every month using current data files from NOAA GHCN v3 (meteorological stations), ERSST v4 (ocean areas), and SCAR (Antarctic stations).
