Bill McGuire is Professor of Geophysical Hazards at University College London and Director of the university's Benfield UCL Hazard Research Centre – Europe's largest, multidisciplinary academic hazard research centre. A volcanologist by inclination and training, he has worked on volcanoes all over the world, and published over three hundred papers, books and articles on volcanoes and other natural hazards. Bill has held the positions of UK National Correspondent of the International Association of Volcanology and Chemistry of the Earth's Interior, and Secretary of the UK Panel of the International Union of Geodesy and Geophysics. He has been a council member of the Geological Society and in 1996 was Senior Scientist at the Montserrat Volcano Observatory. He is a Fellow of the Royal Institution (RI) and a member of the RI’s Science Media Panel. He is currently on the editorial boards of two journals: Disasters and Philosophical Transactions of the Royal Society. Bill was also a member of the Natural Hazard Working Group established by the UK Government in January 2005, in the wake of the Indian Ocean tsunami, to examine the feasibility of global natural hazard early warning systems. In November 2005, he gave the prestigious Natural History Museum Annual Science Lecture. He is currently a member of the Lancet-UCL Commission on the Health Effects of Climate Change and an advisor on natural threats and climate change to HSBC Group.

Bill's recent work has focused on the instability and collapse of volcanoes, volcanic risk and insurance, the potential impact of global geophysical events – about which he has briefed the All-parliamentary Group on the Earth Sciences - and the geological hazard implications of climate change. His most recent academic texts are: Natural Hazards and Environmental Change and World Atlas of Natural Hazards. At UCL, Bill is director of the unique postgraduate certificate course, Natural Hazards for Insurers and instigator and deputy course director of the Masters programme in Geophysical Hazards.

Record of Volcanism Since 7000 B.C. from the GISP2 Greenland Ice Core and Implications for the Volcano-Climate System

Sulfate concentrations from continuous biyearly sampling of the GISP2 Greenland ice core provide a record of potential climate-forcing volcanism since 7000 B.C. Although 85 percent of the events recorded over the last 2000 years were matched to documented volcanic eruptions, only about 30 percent of the events from 1 to 7000 B.C. were matched to such events. Several historic eruptions may have been greater sulfur producers than previously thought. There are three times as many events from 5000 to 7000 B.C. as over the last two millennia with sulfate deposition equal to or up to five times that of the largest known historical eruptions. This increased volcanism in the early Holocene may have contributed to climatic cooling.
