Hansen’s purple crayon is out of control. He has almost no data in the Arctic, as you can see below. The 0.44 anomaly being reported in the map above is unjustifiable. Axel Heiberg Island was cold, and the map above showed it as hot.
We know from people in the Arctic (like the Catlin Survey) that temperatures there have been bitter cold (-35C.) NOAA is currently showing Greenland 15C below normal.
Hansen’s claim above about summers getting hotter is also ridiculous. This is what he wrote in 1999.
Empirical evidence does not lend much support to the notion that climate is headed precipitately toward more extreme heat and drought. The drought of 1999 covered a smaller area than the 1988 drought, when the Mississippi almost dried up. And 1988 was a temporary inconvenience as compared with repeated droughts during the 1930s “Dust Bowl” that caused an exodus from the prairies, as chronicled in Steinbeck’s Grapes of Wrath.
How can the absence of clear climate change in the United States be reconciled with continued reports of record global temperature? Part of the “answer” is that U.S. climate has been following a different course than global climate, at least so far. Figure 1 compares the temperature history in the U.S. and the world for the past 120 years. The U.S. has warmed during the past century, but the warming hardly exceeds year-to-year variability. Indeed, in the U.S. the warmest decade was the 1930s and the warmest year was 1934.
