This is what I had referred to in my article: Climate Change Explained (see side bar on the right). Volcanoes under Glaciers can melt ice, the probability of this is increased in periods when volcanic activity is generally increasing.
Here is the new report from the Guardian.:
This is in addition to 47 already known about and eruption would melt more ice in region affected by climate change
Scientists have uncovered the largest volcanic region on Earth – two kilometres below the surface of the vast ice sheet that covers west Antarctica.
The project, by Edinburgh University researchers, has revealed almost 100 volcanoes – with the highest as tall as the Eiger, which stands at almost 4,000 metres in Switzerland.
Geologists say this huge region is likely to dwarf that of east Africa’s volcanic ridge, currently rated the densest concentration of volcanoes in the world.
