Ice-marginal moraines in the upper Khumbu Valley represent a complete record of regional glacier change between 7.4 ka and the present day
Moraine building modified the response of Khumbu Glacier to climate change after 8 ka
Holocene moraine volume indicates a catchment-wide denudation rate of 0.8–1.4 mm per year
Plain Language Summary
Satellite observations indicate that glaciers in the monsoon-influenced Himalaya are changing rapidly in response to climate change. However, understanding why glaciers are changing requires observing glacier behavior over longer timescales using the glacial geological record. We mapped the geometry and measured the ages of ice-marginal moraines built by two adjacent glaciers in the Everest region of Nepal. The moraines represent a complete record of glacier expansion during cold periods in the monsoon-influenced Himalayan region over the last 8,000 years. Moraines formed by the large Khumbu Glacier and the smaller, steeper Lobuche Glacier also reveal differences in how these glaciers have changed since the last Ice Age. The results are useful to understand how monsoon-influenced Himalayan glaciers respond to climate change, and to improve projections of their future behavior.
