Climate warmer than ‘any time in the last 5,000 years’
A team of researchers from the University of Alaska Fairbanks have been startled by the rapid loss of Arctic permafrost in the face of a succession of unseasonably warm summers.
The team found that the upper layers of the Arctic’s enormous subterranean permafrost has become destabilised in the face of ongoing heatwaves.
In speaking to Reuters, lead researcher Professor Vladimir Romanovsky said that it was evidence of systemic warming of the world’s climate.
“It’s an indication that the climate is now warmer than at any time in the last 5,000 or more years,” Professor Romanovsky said.
Co-researcher Louise Farquharson said that the evidence uncovered is a ‘canary in the coal mine’ for the Arctic.
“It’s very likely that this phenomenon is affecting a much more extensive region and that’s what we’re going to look at next,” Ms Farquharson said.
