Hundreds of dormant volcanoes across the globe—particularly in Antarctica—could become more active thanks to climate change.

Melting glaciers may be silently setting the stage for more explosive and frequent volcanic eruptions in the future, according to research on six volcanoes in the Chilean Andes.

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.
