When ice gets trapped on land as giant ice sheets, it causes the sea level to change, but it doesn’t change by the same amount all around the planet.

In a feedback of fire and ice, thinning ice sheets over geologic hot spots could allow more eruptions, while increased ...

A new study reveals a concerning link between climate change and increased volcanic activity, particularly in glaciated ...

Even the current level of global warming may already have locked in unstoppable ice melt, with a major new study warning of ...

Understanding Why Antarctic Ice Loss Matters Antarctica may seem like another world—cold, distant, and forgotten—but what goes on there is already beginning to affect Antarctica may be remote, but ...

Data out of Chile suggests that as glaciers and ice caps melt in volcanic regions, released pressure and magma build-up makes eruptions increasingly likely — which could lead to a vicious circle where ...

Learn about the new technique being used to study cracks that have formed on Antarctica's unstable Doomsday Glacier.

And the eruptions can make warming worse, melting more glaciers.
