Seven facts you need to know about the Arctic methane timebomb

1. The 50 Gigatonne decadal methane pulse scenario was posited by four Arctic specialists, and is considered plausible by Met Office scientists
2. Arctic methane hydrates are becoming increasingly unstable in the context of anthropogenic climate change and it's impact on diminishing sea ice
3. Multiple scientific reviews, including one by over 20 Arctic specialists, confirm decadal catastrophic Arctic methane release is plausible
4. Current Arctic methane levels are unprecedented
5. The tipping point for continuous Siberian permafrost thaw could be as low as 1.5C
6. Arctic conditions during the Eemian interglacial lasting from 130,000 to 115,000 years ago are a terrible analogy for today's Arctic
7. Paleoclimate records will not necessarily capture a large, abrupt methane pulse

Detailed support for each point is available in the linked article.
