GISS has invented some new corrections to heat the Arctic. Until a few weeks ago, Reykjavik, Iceland looked like the graph below, with the 1930s and 1940s warmer than the present :
Now it looks like this, with the 1930s and 1940s much cooler than the present.
The new technique is called “removing suspicious records” – i.e any record which doesn’t support his theory.
Hansen seems to have adopted a general strategy of warming the present by cooling the 1930s and 1940s.
There is nothing suspicious about records which show a lot of Arctic warming prior to 1940. It is well documented.

By far the largest number of local glaciers in north-east Greenland had receded very greatly during recent decades, and it would not be exaggerating to say that these glaciers were nearing a catastrophe.
In Alaska glaciers had been retreating from 100 to 200 years, the average rate of recession being about 50 feet a year. The Antarctic ice- sheet also showed signs of recent retreat.
“In fact,” said Professor Speight, “no case is recorded of a region of the world in which there are present signs of an advance.
OLD FARMS EXPOSED : Greenland’s Ice is melting and the ruins of mediaeval farm-houses hidden by ice for centuries have already been exposed. In Spitsbergen the mean annual temperature has risen by four degrees since 1912. Ships ply the White Sea and The Gulf of Bothnia three or four weeks longer than they used to. In Iceland and the higher latitudes of Norway farmers are growing barley in soil that was once frozen for seven months each year. But the coming of the new climate is more noticeable, above the world’s snow lines. Glaciers present the most striking evidence . The American geographer, F. E. Matthes, has reported that ‘glaciers in nearly all parts of the world receded regularly during the last 60 years, but especially rapidly during the 1930-40 decade.’
GLACIERS SHRINKING : All glaciers examined from Green land through Scandinavia to Europe are shrinking. And the shrinkage is not limited to high latitudes. Some glaciers in the European Alps have vanished completely. In East Africa, the glaciers on three high volcanoes— Kilimanjaro, Mt. Kenya and Ruwenzori — have been diminishing since they were first observed in 1880. The vast Muir Glacier in Alaska’s Glacier Bay has retreated a full 14 miles’ since 1902.
