| Description | The Northern Hemisphere over the past 30 years has seen an increase in the amount of land area experiencing what NASA scientists define as "extremely hot" summer temperatures, according to a new analysis led by James Hansen at the NASA Goddard Institute for Space Studies. These regions of "extremely hot" temperatures are shown on the map as brown. Hansen and colleagues looked at statistics and linked this increase in extreme heat waves to climate change. These "extremely hot" temperatures covered less than 1 percent of the Northern Hemisphere land surface during the time period 1951 to 1980. Since 2006 these extreme temperatures have covered about 10 percent of this land area. The visualization shows how temperatures by region differed from the 1951-1980 seasonal average for June, July and August. White areas are considered "normal" temperatures, while blues and purples represent colder than usual temperatures. The range of hotter than normal temperatures is defined by the scientists as "hot" (orange), "very hot" (red) and "extremely hot" (brown). |
