Scientists working in one of the world’s fastest warming places found that rapidly retreating glaciers are triggering the release of methane, a potent greenhouse gas that causes global temperatures to rise, into the atmosphere. Here's what to know.
puts those at between zero and 1 million tons of methane per year, underscoring the uncertainty about the scope of the problem.
105,940 tons of methane emissions from its agricultural sector, the largest source of emissions for this gas, in 2021 .Overall, the emissions tied to retreating glaciers in Svalbard would constitute a little over 1 percent of all of Norway’s methane emissions for 2021. Among nations, Norway is itself a relatively small methane emitter.
The latest study “is important because it shows how ubiquitous [methane] seeps, of various origins, are in the environment of retreating glaciers,” Walter Anthony said in an email. “Similar methane rich seeps have been found in Alaska and Greenland along margins of glaciers and the ice sheet.
