Awakening Ancient Pathogens

Global warming is allowing an array of forgotten pathogens to emerge from the thawing permafrost—and possibly reinfect humans.
 
Organic matter like dead animals, moss and plants, long preserved in ice, are now thawing, rotting, and releasing gases that not only spur global warming but create a new breeding ground for bacteria and viruses.
 
Testing Russian permafrost samples for viral threats to humanity, microbiology’s power couple, Jean-Michel Claverie and Chantal Abergel, discovered “extremely abnormal, extremely fancy,” viruses so far harmless to humans. But they are lingering. A thawed reindeer carcass killed in 1941 is the presumed culprit in a Siberian anthrax outbreak last summer.
