Scientists are warning that, across Siberia, vast swathes of ground – normally frozen all year round – are thawing – with potentially devastating consequences for the climate. As it thaws, the earth is believed to be releasing huge amounts of greenhouse gases, accentuating the problem of global warming.
BBC Moscow correspondent Steve Rosenberg has been to the remote Yakutia region to look at how thawing permafrost is affecting not just the climate, but the landscape and livelihoods in Siberia.
