Climbers' urine, fuel melting Everest Base Camp glacier

A study by Nepalese and American scientists found human activity at Everest Base Camp is rapidly melting the Khumbu Glacier. In 2023, fuel consumption caused 94% of human-induced melting, while urine contributed 6%. Surface temperatures are rising 0.28°C per year. Scientists recommend solar power adoption, better waste management, and partial camp relocation.
