Door Chris Mooney, The Washington Post, 19 maart 2018

For some time, scientists fearing the mass release of greenhouse gases from the carbon-rich, frozen soils of the Arctic have had at least one morsel of good news in their forecasts: They predicted most of the gas released would be carbon dioxide, which, though a greenhouse gas, drives warming [much] more slowly than [...] [methane].

[...] Research released [March 19th]  suggests that methane releases could be considerably more prevalent as Arctic permafrost thaws.
