Volcanoes keeping a lid on global warming




Climatologists in the U.S. say that dozens of active volcanoes spewing sulfur dioxide into the stratosphere have been offsetting about a quarter of the greenhouse warming on Earth over the last decade. Study leader Ryan Neely, from the University of Colorado Boulder, explained that sulfur dioxide emissions from Earth’s surface eventually rise 12 – 20 […]

New Slant On Volcanic Climate Change




Scientists have known for some time that airborne volcanic particles (aerosols) can reflect the Sun’s rays back out into space and cool the planet for relatively short periods. But now, British scientists have discovered another cooling mechanism triggered by volcanic activity that has the potential to cool the Earth for much longer periods. Vincent Gauci, […]
