Glacial retreat caused a wave of volcanic activity in southern Chile as the last Ice Age came to an end, according to new research.

As glaciers melt around the world, long-dormant volcanoes may be waking up beneath the ice. New research reveals that massive ice sheets have suppressed eruptions for thousands of years, building up underground pressure.

Glacial melt could increase volcanic activity in North America, New Zealand and Russia, spewing greenhouse gases into the atmosphere.
