Humanity may not be able to savour the sights of some of the world’s iconic glaciers as they will disappear due to climate change by 2050, according to a new analysis by UNESCO. A new study by UNESCO, in partnership with the International Union for the Conservation of Nature, says that glaciers in a third of 50 World Heritage sites are condemned to disappear by 2050, regardless of efforts to limit temperature increases. These include glaciers in the Yellowstone National Park in the United States seen here.

The glaciers of Mount Kilimanjaro, seen here, as well as Mount Kenya, will also be gone by 2050.

Mount Everest, located on the Nepal-Tibet border, will also lose its glaciers. Here, mountaineers are seen on Everest’s summit. Photo: iStock.“This report is a call to action. Only a rapid reduction in our CO2 emissions levels can save glaciers and the exceptional biodiversity that depends on them. COP27 will have a crucial role to help find solutions to this issue,” said Audrey Azoulay, UNESCO’s director-general, said in a statement. Here, Pyrenees National Park, straddling the Franco-Spanish border is shown. It will also lose its glaciers by 2050.
