Hansen is constantly warming the present and cooling the past. The graph below shows changes to GISS reported temperatures since July 15, 2011.
Hansen of course overwrites in situ or deletes his old data, but I have been saving the files to track his cheating.
GISS is also diverging from satellite data at a rate of almost 1C per century. Hansen has to keep the global warming scare alive – the planet depends on it.
