UNESCO predicts the world famous glaciers might disappear by 2050 due to global warming

The United Nations cultural agency UNESCO monitors more than 18,000 glaciers across 50 of its World Heritage sites. It mentions Mount Kilimanjaro apart from the Dolomites in Italy and the Yosemite and Yellowstone parks in the US. The prediction of UNESCO could have serious repercussion. It predicts that around 50 percent of World Heritage glaciers could almost entirely disappear unless the world takes corrective action. It may be possible to preserve them by keeping global temperature rise below 1.5C. UNESCO says World Heritage glaciers make up around 10 percent of the world's glacier areas overall. The worst part is that the world's best-known glaciers are gradually disappearing. That would be a major loss for global tourism. The report's lead author is Tales Carvalho. He estimates that World Heritage glaciers lose around 58 billion tonnes of ice every year on an average. In other words, the loss is equivalent to the total annual volume of water used in France and Spain together. It contributes to almost 5 percent of the global observed sea-level rise. Major glaciers including Mount Kilimanjaro and Dolomites to disappear by 2050, UN report says.

He adds that in order to prevent major glacier retreat worldwide it is necessary to reduce carbon emissions. UNESCO wants local authorities to make glaciers a focus of policy. They can achieve this by improving monitoring and research. They can also implement different measures of risk reduction. Tales Carvalho cautions - "As glacier lakes fill up, they can burst and can cause catastrophic floods downstream.” The timing of the report coincides with the COP27 event in Sharm el Sheikh, Egypt. It would be Africa's first UN climate conference in six years. Incidentally, a recent study found that glaciers in Switzerland lost half of their volume in less than a century. Moreover, the rate of retreat of ice is on the rise. This is a matter of concern.
