DESCRIPTION:Volcanic eruptions have a significant potential to affect the 
 climate system\, the environment and society. In this talk\, I will addres
 s the importance of tropospheric volcanic aerosol ­ whether derived from 
 continuously degassing volcanoes or large-scale Icelandic flood lava event
 s ­ for global aerosol\, radiative forcing of climate and public health.\
 n        \nUsing a global aerosol microphysics model (GLOMAP) together wit
 h volcanological datasets I will show that a future long-lasting Icelandic
  Laki-type eruption has the potential to substantially degrade air quality
  across Europe. Using current epidemiological evidence\, I quantify the po
 llution-induced public health hazard that could arise if such an eruption 
 recurred. I will show that\, based\non the predicted changes in particulat
 e matter concentrations\, up to 142\,000 additional cardiopulmonary fatali
 ties could occur in Europe. Such a volcanic air pollution event would ther
 efore be a severe health hazard\, increasing excess mortality in Europe on
  a scale that exceeds mortality due to seasonal influenza.\n        \nI wi
 ll also discuss the importance of continuously degassing volcanoes such as
  Mt. Etna in Italy for global aerosol and estimates of the anthropogenic c
 loud albedo forcing.
