German Professor Dr. Friedrich Karl Ewert, a retired geologist and data computation expert, undertook a detailed study of NASA-Goddard Institute of Space Study's temperature data series, going all the way back to 1881 and involving 1,153 stations. He discovered NASA-GISS had tampered with raw temperature data to literally invent global warming. Between 2010 and 2012 NASA-GISS altered its own data sets to show a post-WWII warming that never existed. Moreover, apart from the continent of Australia, the planet has been on a cooling trend.
