Global Warming

Scientists have identified at least 150 000 sites in the Arctic (Alaska and Greenland) where methane gas is actively bubbling to the surface, mainly along the edges of lakes where the ice margins are retreating due to the melting ice. The Arctic is the fastest warming region on the planet, and the release of this gas which has been trapped for millennia beneath the ice, together with the methane being released across Siberia due to the melting of the permafrost layer may significantly affect the rate of global warming.
