The latest volcano eruption in Iceland is now being used as an example by the Global Warming fanatics of how thinning ice caps can actually cause volcanoes to erupt. The latest is how thinning ice caps in Iceland are releasing pressure on the ground and creating liquid magma. Freysteinn Sigmundsson, a vulcanologist at the University of Iceland, goes on to say that melting ice caused by Global Warming can influence magmatic systems as seen from the increasing volcano activity at the end of the Ice Age 10,000 years ago apparently because as the ice caps melted, the land rose.
Carolina Pagli, a geophysicist at the University of Leeds in England warns of the risk of volcano eruptions in other ice covered areas such as Antarctica and Alaska because the decrease in pressure on the ground from decreasing ice caps can have effects in deep areas where magma is produced.
Pagli and Sigmundsson wrote a 2008 paper in the scientific journal Geophysical Research Letters about possible links between global warming and Icelandic volcanoes.
Their report said that about 10 percent of Iceland’s biggest ice cap, Vatnajokull, has melted since 1890 and the land nearby was rising about 25 millimetres (0.98 inch) a year, bringing shifts in geological stresses.
