Receding Chilean glacier a sign of accelerating climate change

Scientists say that warm summer temperatures and high rainfall weakened the Grey Glacier’s walls

In the space of just two weeks, two large icebergs broke off the Grey Glacier in Chilean Patagonia—a sign of accelerating climate change, experts say.

The Grey Glacier is one of the main sights in the Torres del Paine  popular with tourists and hikers.

A giant iceberg the size of six football pitches—8.8 hectares (22 acres)—broke away from the glacier on February 20 and another six hectare piece detached on March 7.

It marks the first time two icebergs of such great size have broken off in such quick succession.

The 270  (104 square mile) glacier receded by 500 meters (550 yards), more than half the amount lost over the previous decade.

A smaller  detached in 2017 but Ricardo Jana, a scientist at the Chilean Antarctic Institute, said “the loss of mass over the previous years was definitely smaller than this year.”

Scientists following the glacier’s evolution say it lost around two kilometers in the last 30 years.

A United Nations study in 2018 found that 95 percent of Chile’s 24,100  had receded.

Scientists say that unusually warm summer temperatures—up to 31 degrees Celsius in Patagonia—and high rainfall weakened the glacier’s walls.
