Peak rate of extinction for world's glaciers anticipated by mid-century

With 4° C. of warming, the peak shifts to the mid-2050s and intensifies to around 4,000 lost per year, researchers found.

ZÜRICH (AN) – An international team of scientists projects that up to 4,000 glaciers a year will vanish by the mid-2050s, a maximum rate of disappearance that would be three to five times greater than today.

The study, led by researchers at ETH Zürich and published in Nature Climate Change on Monday, shifts the focus from total ice mass loss to the sheer number of individual glaciers at risk of vanishing entirely, warning drastic cuts to emissions are needed to save tens of thousands of them.
