New Scientist Climate warning as Siberia melts - News
"THE world's largest frozen peat bog is melting. : An area stretching for a million square kilometres across the permafrost of western Siberia is turning into a mass of shallow lakes as the ground melts, according to Russian researchers just back from the region.
The sudden melting of a bog the size of France and Germany combined could unleash billions of tonnes of methane, a potent greenhouse gas, into the atmosphere.
The news of the dramatic transformation of one of the world's least visited landscapes comes from Sergei Kirpotin, a botanist at Tomsk State University, Russia, and Judith Marquand at the University of Oxford.
Kirpotin describes an 'ecological landslide that is probably irreversible and is undoubtedly connected to climatic warming'. He says that the entire western Siberian sub-Arctic region has begun to melt, and this 'has all happened in the last three or four years'.
What was until recently a featureless expanse of frozen peat is turning into a watery landscape of lakes, some more than a kilometre across. Kirpotin suspects that some unknown critical threshold has been crossed, triggering the melting.
Western Siberia has warmed faster than almost anywhere else on the planet"
