Photos: Melting of world's glaciers called 'alarming'
According to an "alarming" study in the journal Nature, the world's 220,000 glaciers are melting much faster now than than they did 15 years earlier.

In this July 22, 2017, file photo, a polar bear climbs out of the water to walk on the ice in the Franklin Strait in the Canadian Arctic Archipelago. Climate scientists point to the Arctic as a place where climate change is most noticeable with dramatic sea ice loss, a melting Greenland ice sheet, receding glaciers and thawing permafrost.

This satellite photo provided by UNITAR-UNOSAT, and taken by USGS/NASA on Sunday, Aug. 25, 2019, shows the Mont Blanc massif in the Italian Alps near Courmayeur. Italian officials sounded an alarm in 2019 over climate change due to the threat from a fast-moving melting glacier, located on the Grande Jorasses peak of the massif. (USGS/NASA via AP)

Floods that slammed into two hydroelectric plants and damaged villages in northern India were set off by a break on a Himalayan glacier upstream. (AP Photo/Tashi Sherpa)
Glaciers are melting faster, losing 31% more snow and ice a year than 15 years earlier, satellites show. Scientists blame human-caused climate change.
Researchers have recovered a treasure trove of World War I artifacts from a cave shelter in northern Italy, revealed by the melting of a glacier.
