IGBP Symposium on Ecosystem Impacts of Geoengineering

Workshop Report (Draft 1/09/12: Executive Summary and Submitted Manuscript)

January 31, 2011, 8:30am-8:30pm
Scripps Forum, Scripps Institution of Oceanography

Geoengineering, techniques to counteract global warming by modifying the Earth system rather than removing the primary causative agents – the greenhouse gases, has been suggested as a means to counteract dangerous climate change. Many proposed geoengineering schemes may involve important and unexplored consequences to the ecosystems that populate our planet. These consequences result from intentional and unintentional changes to regional climates in ways that affect sensitive populations. However, to date there has been very little research carried out to evaluate the potential hazards of geoengineering schemes on these sensitive ecosystems. This workshop will bring together ecosystem researchers and geoengineering researchers for a special workshop on Ecosystem Impacts of Geoengineering. The objectives of this workshop are (1) to build connections between the ecosystem-research and geoengineering-research communities, (2) to evaluate scientific uncertainties that affect the potential impacts of geoengineering on ecosystems, (3) to expose ecosystem researchers to current geoengineering research, and (4) to generate feedback for geoengineering researchers on potential ecosystem hazards of geoengineering.
