Temperature Adjustments Transform Arctic Climate HistoryPosted: February 13, 2015
By Paul Homewood
We are told that the biggest sign of “climate change” is the rapidly warming Arctic, even called the World’s thermometer, proof that global warming cannot have stopped.
Certainly, the evidence of this from GISS is persuasive.
Yet it is well established that the Arctic warmed up rapidly during the 1930’s and 40’s, before temperatures plunged in the 1960’s and 70’s. James Hansen, himself, recognised this, as the graph below from his 1987 paper Global Trends of Measured Surface Air Temperature , showed.
So how much is what we have been seeing in recent years just part of that cycle? How much warmer is the Arctic now than it was 80 years ago?
Quite a lot, according to GISS.
But can we trust their figures? We saw previously how the temperature history for Paraguay, and a large slice of the surrounding region, had been altered…
