How can glaciers accelerate erosion




















The erosive power of glaciers varies considerably, with some of the most rapid glacial erosion happening in mid-latitude climates. It means that as the Earth gets warmer and glaciers accelerate, the rate of glacial erosion will increase. A result will be more rapid carving of our landscape by glaciers with a corresponding increase in the levels of sediment and mud carried in alpine streams and rivers.

The finding applies to faster-moving glaciers in mountainous mid-latitude regions, but may not apply to polar glaciers that move more slowly. Young, N. Overeem, I.
