The vast expanse of sea ice around Antarctica has suffered a “precipitous” fall since 2014, satellite data shows, and fell at a faster rate than seen in the Arctic. The plunge in the average annual extent means Antarctica lost as much sea ice in four years as the Arctic lost in 34 years. The cause of the sharp Antarctic losses is as yet unknown and only time will tell whether the ice recovers or continues to decline. But researchers said it showed ice could disappear much more rapidly than previously thought. Unlike the melting of ice sheets on land, sea ice melting does not raise sea level. But losing bright white sea ice means the sun’s heat is instead absorbed by dark ocean waters, leading to a vicious circle of heating.

The amount of ice floating in the sea across Antarctica has fallen to a record low just three years after hitting an all-time high. Floating ice levels near the continent increased steadily from 1979 to 2014, when it hit 4.9m square miles, the highest amount on record. But by 2017 the amount of ice was at 4.1m square miles, its lowest ever mark, according to a Nasa study of satellite data. The amount of sea ice lost in those three years would cover an area bigger than the size of Mexico.

Vast swathes of Dundee and Broughty Ferry could be lost to the River Tay if global warming continues unabated. A new interactive map called Surging Seas shows just how much of the city could be lost over the next century if ice caps melts and the sea levels rise. Just a two degree increase in temperature would see City Quay and large parts of Riverside Drive under water. Large parts of the Port of Dundee would also be flooded.
