NASA has said the Antarctic iceberg A-76A may soon disappear.
This iceberg is 135 km long and 26 km wide.
A third of glaciers at 50 World Heritage sites will disappear by 2050, says UNESCO
Washington, US space agency NASA has expressed concern over the Antarctic iceberg A-76A, which was once the world’s largest glacier, amid the ongoing UN climate summit in Egypt. In a satellite image released by NASA, the largest remaining piece of the Antarctic iceberg appears to soon be engulfing the sea. According to the space agency, this glacier will soon melt and disappear.
According to the US National Ice Center, the iceberg is 135 kilometers long and 26 kilometers wide, about twice the size of London. This glacier is the largest of the A-76 the size of “Rhode Island”, which was the former largest iceberg in the world. It broke off from the western part of the Rhone Ice Shelf in Antarctica in May 2021 and then split into three fragments 76A, 76B and 76C. Iceberg 76A is the largest of these pieces.
According to the Live Science report, this glacier was slowly flowing with Antarctica for more than a year, but now its melting has accelerated and the iceberg is heading towards its end. Recall that on October 31, the photo of this iceberg was taken by NASA’s Terra satellite. The glacier currently floats in South Africa between Cape Horn and South Shetland, a narrow strait connecting the Pacific and Atlantic oceans. The image was posted online by NASA’s Earth Observatory on November 4.
A third of glaciers will disappear by 2050
A UNESCO report indicates that if the current situation continues, a third of the 50 World Heritage glaciers will disappear by 2050. In Africa, the glaciers of all the World Heritage sites will disappear by 2050, including the Park Kilimanjaro National Park and Mount Kenya.
In Europe, some glaciers in the Pyrenees and the Dolomites could also disappear after three decades. The organization added that if the temperature increase does not exceed 1.5°C compared to the pre-industrial period, it is still possible to save glaciers in the remaining two-thirds of the sites. However, this objective does not appear to be achieved in any of the reports.
