Global alert: Glaciers are melting at unprecedented rate

Global alert: Glaciers are melting at unprecedented rate Glaciers appear on almost every continent providing a large part of the fresh water we consume. But this indispensable resource is now threatened. Today we know that the glaciers in UNESCO World Heritage sites are retreating at an accelerated rate because of climate change. According to the latest report by UNESCO, in partnership with IUCN, World heritage glaciers: sentinels of climate change, they lose on average some 58 billion tons of ice every year – and contribute to almost 5 per cent of global sea-level rise.  View media One-third of UNESCO World Heritage glaciers will disappear by 2050 because of climate change. If there is a silver-lining, it is that the other two thirds could be saved, should the rise in global temperatures not exceed 1.5 °C compared to the pre-industrial period. Urgent action is needed to preserve these iconic places for future generations. This article was originally published in The UNESCO Courier: Maths Counts (January - March 2023) Participe da conversa
