evidence: The false-color images on this page show a few glaciers in the Himalayas. The images above show the high glacier passes of Nanpa La and Nup La, located around 30 miles (50 kilometers) northwest of Mount Everest, during fall on October 13, 2020 (left) and in winter on January 17, 2021 (right). The images below show Rolwaling Glacier, located 20 kilometers (30 miles) south of Nanpa La. All images were acquired by the Operational Land Imager (OLI) on Landsat 8 using bands 7-5-4. [...] Melting season in the region around Mount Everest is usually concentrated during the summer monsoon (April to September). In the past year, however, abnormally warm temperatures have extended the melting period by four months. As of January 22, 2021, weather stations at Everest base camp reported maximum temperatures above freezing for eight days that month. On January 13, temperatures peaked at 7°C (45°F). "We have been basically seeing spring and summer-like conditions in the middle of winter," said Tom Matthews, a climate scientist at Loughborough University (United Kingdom) who helps manage weather stations at Mount Everest placed during the Rolex National Geographic Expedition. These melting events, said Matthews, are associated with pulses of warm air carried in by prevailing winds from the west.
