In the ongoing culture war among climate scientists, climate scientologists and climate deniers, few things stands out like the effect of volcanoes. Volcanoes are well-known for cooling the climate but how much has been unclear, leading to radically differing claims and interpretations. Atmospheric chemists from the Tokyo Institute of Technology and the University of Copenhagen say that patterns of isotopes found in ancient volcanic sulfur trapped in ice cores, and patterns due to stratospheric photochemistry, are a way to say for sure which historic episodes of global cooling were caused by volcanic eruptions. read more
