In 1991, the Pinatubo volcano eruption was a disaster for the Philippines and the effects were noticed across the world – it threw tons of ash and other particles into the atmosphere, which caused less sunlight to reach the Earth’s surface. Global temperatures dropped by half a degree for years after that.

Clearly, volcanic eruptions can have a strong short-term impact on climate but a group of researchers are delighting doomsday believers by contending climate change will have an impact on volcanic eruptions. The researchers from GEOMAR Helmholtz Centre for Ocean Research Kiel and Harvard University say they have strong evidence by using models of major volcanic eruptions around the Pacific Ocean over the past 1 million years.
