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. Bloomberg reported that temperatures in parts of the country soared to 42 degrees Celsius (108 degrees Fahrenheit), and the Wall Street Journal reported that fire- and drought-inducing heat was expected to continue until at least August 12.

This map 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.

Not all parts of the Russian Federation experienced unusual warmth on July 20–27, 2010. A large expanse of northern central Russia, for instance, exhibits below-average temperatures. Areas of atypical warmth, however, predominate in the east and west. Orange- and red-tinged areas extend from eastern Siberia toward the southwest, but the most obvious area of unusual warmth occurs north and northwest of the Caspian Sea. These warm areas in eastern and western Russia continue a pattern noticeable earlier in July,and correspond to areas of intense drought and wildfire activity.

Bloomberg reported that 558 active fires covering 179,596 hectares (693 square miles) were burning across the Russian Federation as of August 6, 2010. Voice of America reported that smoke from forest fires around the Russian capital forced flight restrictions at Moscow airports on August 6, just as health officials warned Moscow residents to take precautions against the smoke inhalation.
