Description: Urine Is Contributing to Ice Melt at Everest Base Camp, Study Finds Human waste and fuel consumption at Mount Everest Base Camp are contributing to local melting of the Khumbu Glacier, according to new research involving scientists from Nepal and the United States. Everest Base Camp is established directly on glacier ice during the spring climbing season. Thousands of climbers, guides and support workers temporarily occupy the site, producing large quantities of urine and consuming fuel for cooking, heating and electricity. Researchers estimate that more than 6,000 litres of urine may be produced daily during the busiest period. Because urine leaves the body at a temperature considerably warmer than the surrounding ice, it transfers heat to the glacier. The study calculated that this thermal energy could theoretically melt approximately 154 tonnes of ice during one climbing season. However, urine does not chemically dissolve the glacier, and researchers did not directly observe an isolated block of ice melting from urine alone. The figure represents a calculated melt equivalent based on heat transfer. Fuel combustion creates a much larger local impact. Heat generated by kerosene, liquefied petroleum gas and petrol could account for more than 2,300 tonnes of ice melt. Combined camp activities were estimated to produce enough energy to melt approximately 2,492 tonnes. Scientists stressed that global climate change remains the main cause of Himalayan glacier retreat. Human activity at base camp creates an additional, concentrated source of heat and pollution. Urine and other waste may also introduce nutrients, microorganisms and contaminants into glacier meltwater. Researchers have therefore recommended stronger waste-management systems and consideration of relocating the camp to nearby ice-free ground. Sources: Recent study coverage Subscribe to FactTechz
