Summary of “Lakes are bubbling and hissing with a dangerous greenhouse gas, methane, as the Arctic thaws”

Katey Walter Anthony has studied some 300 lakes across the tundras of the Arctic.
The volume of gas wafting from it could deliver the climate system another blow if lakes like this turn out to be widespread. The first time Walter Anthony saw Esieh Lake, she was afraid it might explode – and she is no stranger to the danger, or the theatrics, of methane.
In 2010, the University of Alaska at Fairbanks posted a video of the media-savvy ecologist standing on the frozen surface of an Arctic lake, then lighting a methane stream on fire to create a tower of flame as tall as she is.
Arctic lakes that don’t freeze Walter Anthony, who grew up close to Lake Tahoe, was captivated by Arctic lakes at 19, when she spent a summer at Siberia’s picturesque Lake Baikal.
A week before the trip, Walter Anthony had published a major study delivering worrisome news about Arctic lakes in general.
That’s despite the fact that the lakes would cover less than 6 percent of the total Arctic land surface.
Later, after processing his data, he produced an initial estimate that the lake was producing two tons of methane gas every day – the equivalent of the methane gas emissions from about 6,000 dairy cows.
Some scientists say they’re not sure yet how bad Arctic lakes will be for the climate or whether they will indeed cause emissions from permafrost to double.
