The facts section states that the millions of tons of methane trapped in the Arctic ice are a factor not commonly taken into account in future climate models
So basically the article argues that the IPCC is stupid enough not to account for methane that's released from Arctic ice in their models. Then because the mainstream climate scientists are so wrong in their science, we should do something about global warming?
I move to taboo "mainstream." It's being so often used as a swear word now that it has lost its meaning.
Only the first half of this page is devoted to stating facts; the latter half is a call for political action. The facts section states that the millions of tons of methane trapped in the Arctic ice are a factor not commonly taken into account in future climate models, and its release will very quickly worsen global warming to the point of posing a serious existential risk.
