Geologic evidence for how volcanoes have driven climate change throughout Earth history Peter L Ward. September 22, 2016 United Nations “Climate change refers to long-term shifts in temperatures and weather patterns, mainly caused by human activities, especially the burning of fossil fuels.” A balance driven by plate tectonics between frequent explosive volcanic eruptions and persistent effusive, basaltic eruptions provides a very clear and detailed explanation for climate change throughout Earth history and for why 2016 is the hottest year on record. Volcanoes rule climate. Major effusive, basaltic eruptions punctuate the geologic time scale. A talk given on September 6, 2016, at the Geological Society of London.
