Thawing Permafrost In Sweden Releases Less Methane Than Feared

A study in northern Sweden found that melting permafrost released one tenth as much methane as expected, suggesting emissions from thawing Arctic tundra could be less than previously feared…

For the study, scientists gauged emissions from one swath of permafrost that thawed in the 1980s and another that thawed 10 to 15 years later. Emissions in the first area were 10 times less than in the second. That’s because as ice melted underground in the first area, water on the surface began to sink down into the soil. As the surface dried out, new plants emerged that helped keep methane emissions buried underground.
