Scientists first discovered significant cracks in the ice shelf a decade ago, but in the last two years there have been two major breaks.
An iceberg nearly the size of Greater London broke off the Brunt Ice Shelf in Antarctica on Sunday according to the British Antarctic Survey. The BAS Halley Research Station is located on the Brunt Ice Shelf and glaciologists say the research station is safe. The iceberg is around 600 square miles, or 1550 square kilometers. The researchers say this event was expected and not a result of climate change.
” Researchers at the data center say the low sea ice has been due in part to a large band of warmer-than-normal air temperatures, which climbed to 2 degrees Celsius above average over the Ross Sea in November and December. Strong winds have also hastened the sea ice decline, they reported. Recent data shows the sea ice has not since recovered, suggesting the continent could end the summer with a new record on the books for the second year in a row.
