Melting permafrost in Arctic will have $70tn climate impact - study

Study shows how destabilised natural systems will worsen man-made problem The release of methane and carbon dioxide from thawing permafrost will accelerate global warming and add up to $70tn (?54tn) to the world's climate bill, according to the most advanced study yet of the economic consequences of a melting Arctic.If countries fail to improve on their Paris agreement commitments, this feedback mechanism, combined with a loss of heat-deflecting white ice, will cause a near 5% amplification of global warming and its associated costs, says the paper, which was published on Tuesday in Nature Communications.
