Researchers Warn Melting Permafrost May Awaken 'Giant Viruses'

Yet another giant prehistoric virus has been unearthed in the frozen tundra of Siberia, where scientists warn climate change is melting the permafrost and awakening potentially dangerous microscopic pathogens. 

Reporting this week in the flagship journal of the U.S. National Academy of Sciences, French researchers announced the discovery of Mollivirus sibericum, found in the permafrost of northern Russia.

“We cannot rule out that distant viruses of ancient Siberian human populations could re-emerge as Arctic permafrost layers melt and/or are disrupted by industrial activities.”

The researchers plan to “wake up” the 30,000-year-old “Frankenvirus,” but not until they verify that the bug cannot cause animal or human disease.

As climate change warms Arctic and sub-Arctic regions at more than twice the global average, permafrost is becoming less permanent. Last year, the same team of French virus-hunters discovered another giant virus strain, Pithovirus sibericum, in the same sample of Arctic permafrost.
