Scientists amazed as Canadian permafrost thaws 70 years early

Latest evidence of global warming suggests the temperatures are warmer than at any time in the past 5,000 years, according to Reuters. 

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 destabilized the upper layers of giant subterranean ice blocks that had been frozen solid for millennia.

“What we saw was amazing,” Vladimir E. Romanovsky, a professor of geophysics at the university, told Reuters by telephone. “It’s an indication that the climate is now warmer than at any time in the last 5,000 or more years.”

With governments meeting in Bonn this week to try to ratchet up ambitions in United Nations climate negotiations, the team’s findings, published on June 10 in Geophysical Research Letters, offered a further sign of a growing climate emergency.
