GEOGRAPHY IN THE NEWS:
Permafrost is proving to be not as "perma" as we had thought. Using recently declassified spy satellite images of the former Soviet Union, scientists have been able to document changes to the Siberian tundra. As permafrost melts, it not only releases trapped methane and carbon dioxide, it also enables the growth of trees and shrubs, which absorb, rather than reflect, solar energy and promote further localized warming. Researchers estimate that for every 1 degree Celsius increase in global temperature, an area of permafrost larger than India will be lost. www.iflscience.com/environment/for-every-1c-of-warming-a-part-of-the-permafrost-the-size-of-india-will-melt/all/
