Door Chris Mooney, The Washington Post, 19 maart 2018For 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.

Trump ‘poses the single greatest threat’ to our climate, bombshell UN report makes clear
Door Joe Romm, Climate Progress, 8 oktober 2018
[...] As the planet warms from 1.5°C to 2°C, the risks grow rapidly for some very dangerous tipping points, including the irreversible collapse of the West Antarctic ice sheet (which would raise sea levels 20 feet).
The report notes that “Limiting global warming to 1.5°C rather than 2°C is projected to prevent the thawing” of as much as 1 million square miles of permafrost. And that matters because the northern permafrost contains twice as much carbon as the atmosphere does today.
