Thawing Permafrost: Welcome Back, Anthrax?


According to researchers, an untold number of dangerous pathogens and diseases frozen beneath the ground for millennia could be unleashed as the Arctic's permafrost melts. The Intergovernmental Panel on Climate Change estimates that the area of the permafrost will decrease 20 to 35 percent by 2050, while the United Nations Environmental Programme estimates the depth of thawing could increase by 30 to 50 percent by 2080.
