The whole western Siberian sub-Arctic region has started to thaw
The world's largest frozen peat bog is melting, which could speed the rate of global warming, New Scientist reports.
The huge expanse of western Siberia is thawing for the first time since its formation, 11,000 years ago.
The area, which is the size of France and Germany combined, could release billions of tonnes of greenhouse gases into the atmosphere."
