A chunk of Antarctic ice about seven times the size of Manhattan has collapsed, scientists said Tuesday, putting an even greater portion of glacial ice at risk.
Such occurrences are “more indicative of a tipping point or trigger in the climate system,” said Sarah B. Das, a scientist at the Woods Hole Oceanographic Institution in Massachusetts.
The rest of the Wilkins Ice Shelf, which is about the size of Connecticut, is holding on by a narrow beam of thin ice. Scientists worry that it too may collapse.
Vaughan had predicted that the Wilkins shelf would collapse about 15 years from now. The part that recently gave way made up about 4% of the overall shelf, but it was an important part that can trigger further collapse.
“The most dramatic early consequences of the climate crisis are in the least accessible areas: near the North Pole and the South Pole,” said former vice president Al Gore. “Since it’s not on live TV, it doesn’t command as much attention as it should.” –from several sources, including CNN
