Russia in Heat

In the summer of 2010, the Russian Federation had to contend with multiple natural hazards: drought in the southern part of the country, and raging fires in western Russia and eastern Siberia. The events all occurred against the backdrop of unusual warmth. Temperatures in parts of the country soared to 42 degrees Celsius (108 degrees Fahrenheit).


The map above shows temperature anomalies for the Russian Federation from July 20–27, 2010, compared to temperatures for the same dates from 2000 to 2008. The anomalies are based on land surface temperatures observed by the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Terra satellite. Areas with above-average temperatures appear in red and orange, and areas with below-average temperatures appear in shades of blue. Oceans and lakes appear in gray.

Globally (see map below), June through August of 2010, according to the Goddard Institute for Space Studies (GISS) analysis, was the fourth-warmest summer period in GISS’s 131-year-temperature record. The same months during 2009, in contrast, were the second warmest on record. The slightly cooler 2010 summer temperatures were primarily the result of a moderate La Niña (cooler than normal temperatures in the equatorial Pacific Ocean) replacing a moderate El Niño (warmer than normal temperatures in the equatorial Pacific Ocean).
