Climate change: Warmth shatters section of Greenland ice shelf

A big chunk of ice has broken away from the Arctic’s largest remaining ice shelf – 79N, or Nioghalvfjerdsfjorden – in north-east Greenland.

The ejected section covers about 110 square km; satellite imagery shows it to have shattered into many small pieces.

The loss is further evidence say scientists of the rapid climate changes taking place in Greenland.

“The atmosphere in this region has warmed by about 3C since 1980,” said Dr Jenny Turton.

“And in 2019 and 2020, it saw record summer temperatures,” the polar researcher at Friedrich-Alexander University in Germany told BBC News.

Nioghalvfjerdsfjorden is roughly 80km long by 20km wide and is the floating front end of the Northeast Greenland Ice Stream – where it flows off the land into the ocean to become buoyant.

At its leading edge, the 79N glacier splits in two, with a minor offshoot turning directly north. It’s this offshoot, or tributary, called Spalte Glacier, that has now disintegrated.
