.. and your name will be mud.

From The Guardian:

Permafrost at outposts in the Canadian Arctic is thawing 70 years earlier than predicted, an expedition has discovered, in the latest sign that the global climate crisis is accelerating even faster than scientists had feared.

A team from the University of Alaska Fairbanks said they were astounded by how quickly a succession of unusually hot summers had destabilised the upper layers of giant subterranean ice blocks that had been frozen solid for millennia...

Scientists are concerned about the stability of permafrost because of the risk that rapid thawing could release vast quantities of heat-trapping gases, unleashing a feedback loop that would in turn fuel even faster temperature rises.

These people have a very one-dimensional view of this and show no interest in what it was like millennia ago.

Ask yourself, "What is permafrost?". To summarise the explanation on Wiki, some areas used to support plant life in earlier, warmer times (which created the soil in which the plants grew, which created more soil etc) but these areas gradually froze over, the vegetation died and rotted away, hence the methane trapped in it.

There's no hard dividing line between 'soil which is still warm enough to support plant life' and 'soil which isn't'. If the latter category warms up a bit, after a couple of years, it will be normal soil with normal vegetation again. We've got to assume that normal soil with normal vegetation isn't some catastrophe-inducing, methane-belching horror, or else there'd be far more methane in the atmosphere than there is (about 2 parts per million).

So sorry, I see nothing to panic about. The methane emitting phase is just the awkward teenage phase while soil moves from being frozen to supporting plant life again.
