We would like to invite you to consider submitting an abstract to an upcoming session on the "Climatic and Human Impacts of Volcanism during the Quaternary" at the upcoming INQUA 2019 Congress in Dublin, Ireland, July 2019. The focus of the session is very broad and we welcome submissions from any of the many fields addressing climatic and human impacts of volcanism in any period of the Quaternary, from deep past to the present.
There is now just a few days away before the abstract submission deadline (9th Jan) - see all the needed details at the link below.
Session description:
Volcanic eruptions produce regional to global climatic impacts. Global-scale impacts arise primarily from the injection of sulfur dioxide into the stratosphere, where it oxidizes to form sulfate aerosols, leading to changes in atmospheric clarity and an associated backscattering of incoming solar radiation. The net temperature impact of these aerosols is a short-term but potentially large decrease in global mean surface temperatures. Patterns of atmospheric circulation and precipitation can also be impacted, leading to complex regional hydroclimatic impacts. Explosive volcanic eruptions have occurred during the Quaternary on a frequency and magnitude (e.g., Toba super-eruption) far beyond the range of contemporary human experience. Studying the impacts of such eruptions in climate model simulations, as well as examining the fingerprints of such eruptions in geologic deposits (e.g., ice cores) and proxy records (e.g., tree-rings and others) provides valuable insight into the likelihood and consequences of this major geological and climatic hazard. Climate models, proxy-based palaeoclimatic reconstructions and instrumental data do not, however, always agree on the climatic impact of major historic eruptions, pointing to the need for further research. Volcanically induced climate changes also provide tests of societal vulnerability and response to abrupt and severe climatic variability. Under the remit of the PAGES (Past Global Changes) Volcanic Impacts on Climate and Society (VICS) Working Group, this session thus invites contributions that examine how major eruptions have affected climate and societies, using climate modelling, historical, archaeological, palaeoecological and other records, to further our understanding of the potential climatic and societal impacts of past and future eruptions.
