Arctic ice could vanish in summers this century even if govts achieve climat target - Report

Arctic ice could vanish in summers this century even if govts achieve climat target - ReportUnder the 2015 Paris agreement, governments set a goal of limiting the rise in average world temperatures to well below 2C (35.6F) above pre-industrial times, with an aspiration of just 1.5C.

This is reported by The Guardian.

“The 2C target may be insufficient to prevent an ice-free Arctic,” James Screen and Daniel Williamson of Exeter University wrote in the Nature Climate Change journal after a review of ice projections.

A 2C rise would still mean a 39% risk that ice would disappear in the Arctic Ocean in summers, they said. Ice was virtually certain to survive, however, with just 1.5C of warming.

They estimated a 73% probability that the ice would disappear in summers unless governments made deeper cuts in emissions. The scientists estimated temperatures would rise 3C on current trends.

This month the extent of Arctic sea ice is rivalling 2016 and 2015 as the smallest for the time of year since satellite records began in the late 1970s. The ice reaches a winter maximum in March and a summer minimum in September.

“In less than 40 years, we have almost halved the summer sea ice cover,” said Tor Eldevik a professor at the Bjerknes Centre for Climate Research at the University of Bergen in Norway, who was not involved in the study.

He predicted sea ice would vanish in the Arctic Ocean in about 40 years on current trends.
