Climate change a key reason for drastic increase of volcanic eruptions

Scientists tasked to study how the climate effects volcanic eruptions throughout history have come to a jarring conclusion recently. In an experiment focusing on volcanic upsurges in Iceland about 5000 years ago, scientists found that climate change can increase the chances of drastic eruptions. Decreased pressure on magma in the earth’s crust is caused by melting glacial ice. The less pressure on magma, the more chances for eruptions, at least according to Graeme T. Swindles, an Earth System Dynamics professor at the University of Leeds. “After glaciers are removed the surface pressure decreases, and the magmas more easily propagate to the...
