A new study has found melting Arctic glaciers are releasing dangerous methane. One B.C. researcher says it's a warning sign that Canada's melting North could be part of a climate feedback loop.
Glaciers thawed by climate change on an Arctic island are opening up a path for subterranean methane to come bubbling to the surface — a phenomenon that risks deepening the climate crisis, a new study has found.
Most people know it as the gas they use to cook on gas stoves or heat gas boilers, but when released into the atmosphere, methane produces a greenhouse effect more than 80 times as potent than carbon dioxide over the first 20 years. It's such a powerful warming agent that the Intergovernmental Panel on Climate Change estimates methane has contributed around 30 per cent of observed human-caused global warming to date.
“It's a really interesting feedback cycle where the rising global temperatures are leading to the melting of the glaciers. And this is leading to more methane released, which slightly increases the rate of further temperature change.” Up from the ground comes a bubbling gas For thousands of years, the island's glaciers have sat on top of a frozen surface, together acting like a ‘cryospheric cap’ preventing underground methane deposits from escaping into the atmosphere.
