Very large and unexpected burst of methane in the Arctic tundra shows new study out in Nature.    

The newly discovered surge of greenhouse gas is brought to you by International Polar Year. Thanks to that research push, a team led by biogeochemist Torben Christensen of Lund University, Sweden, got a two-month extension on the usual field season at a monitoring station in northeast Greenland. Scientists have been measuring methane emissions from far-northern tundra during the growing season for decades, but it had been assumed that once methane levels taper off in late summer, they stay at next to nil over the freezing fall and winter.
