Climate Change may Cause more Volcanic Activity

A study published last month in the the journal Geology says that climate change may cause more volcanic activity.

The report points to melting glaciers as the cause. The glaciers are applying pressure to to volcanoes which is preventing magma from reaching the surface.

As glaciers melt it will release the pressure and it may cause magma to rise and erupt.

4,500 to 5,500 years ago when it was much colder there were fewer eruptions in Iceland. Scientists say this may be proof that melting glaciers can cause more volcanic activity.

Scientists have identified 91 volcanoes hidden beneath the massive ice sheet covering west Antarctica, revealing one of the world's largest volcanic regions.

A volcano is a rupture in the crust that allows hot lava, volcanic ash, and gases to escape from a magma chamber below the surface.

If a volcano were to erupt under a glacier it is unlikely that it would explode through the glacier.

However, if enough lava were to escape, it could melt the glacier.
