Iceberg A-76- World’s largest iceberg breaks off in Antarctica as glaciers retreat:


Context:

Iceberg A-76 calved from the western side of the Ronne Ice Shelf in Antarctica and is now floating on the Weddell Sea.

  • Measurements taken from satellites and planes confirm it’s now the world’s largest.
  • It measures around 170 kilometers (105 miles) long and 25 kilometers (15 miles) wide.

What’s the Concern?

The Antarctica ice sheet is warming faster than the rest of the planet, causing melting of snow and ice covers as well as the retreat of glaciers, especially around the Weddell Sea. As glaciers retreat, chunks of ice break off and float adrift until they break apart or crash into land.
