Permafrost degradation spreads in High Arctic

Polar deserts in Canada’s High Arctic are undergoing rapid changes as increases in summer air temperatures lead to permafrost thaw, leaving giant horseshoe-shaped pockmarks on the barren terrain, according to a new study. The study by McGill University researchers, published»

Permafrost collapse is accelerating carbon release, say scientists

A new study has found that permanently frozen ground called permafrost is melting much more quickly than previously thought and such abrupt thawing “increases permafrost carbon release projections by about 50 per cent.” Melting permafrost releases methane which is a»

Permafrost thawing faster than previously thought: study

Global warming will thaw about 20 per cent more permafrost than previously thought, according to a new international research study. The study, published in Nature Climate Change, suggests that as the planet warms toward two degrees Celsius above preindustrial levels nearly»
