Temperature corrections of the Northern Hemisphere

Hide The Decline
"Most skeptics are aware, but it cannot be repeated too often: Temperature data presented before the global warming movement really started in the mid 1980´ies compared with recent official temperatures shows that the temperature trends 1940-1978 has been changed fundamentally. .....History has been rewritten.The original 1976 temperatures from National geographic for 1935-75 shows almost 0,5 degrees Celsius decline. This is why scientists world wide became worried about a coming ice age.In 2008 according to CRU (and thus to some extend GHCN) the temperature decline 1935-75 has been reduced to approximately 0,15 degrees Celsius according to CRU. The decline appears reduced approximately 0,34K So approximately 70% of the decline in temperatures after 1935-40 has been removed, it seems. .."
