Russia and Canada Heat Up Faster Than the Arctic [Slide Show]

New maps show that temperatures are rising quickest across Earth’s northern midlatitudes

Sporadic in 1950: Warming around Earth (orange and red) has picked up in many spots compared with 1901 but is unevenly distributed, with some areas cooling (blue). (Temperature units are in kelvins.) Zhaohua Wu/Florida State University
Semiarid Focus in 1960: As in 1950, warming still seems to concentrate in semiarid regions of the world. Zhaohua Wu/Florida State University
North More Than South in 1970: By now, it becomes clear that warming is predominately in the Northern Hemisphere. Zhaohua Wu/Florida State University
Cooling Disappears in 1980: The blue regions, which show cooling, are waning. Zhaohua Wu/Florida State University

Rise Quickens in 1990: Hotter regions (orange and red) blanket most of the Northern Hemisphere. Zhaohua Wu/Florida State University
Red Hot in 2000: Large temperature increases bubble up across the Northern Hemisphere, and grow more intense in the Southern Hemisphere as well, although less widespread. Zhaohua Wu/Florida State University
Upper Latitudes Outrun the Arctic in 2009: Although the Arctic is certainly warming significantly in 2009, the most recent year of data, northern midlatitudes—central Canada, northern Europe and southern Russia—heat up even faster... Zhaohua Wu/Florida State University
