CORVALLIS, Ore. - Oregon State University will host a fall lecture series examining the potential of "geoengineering" to mitigate the impacts of future climate change, bringing three international scientists to Corvallis to present the latest research in this emerging field.

The first event in the series will begin on Wednesday, Oct. 5, with a lecture by Florida State University scientist Kristine Harper. Her talk, "Experiments in Geoengineering: Controlling the Weather in 20th-Century America," will begin at 7 p.m. in LaSells Stewart Center. She is a visiting researcher at Aarhus University in Denmark.

Geoengineering has been described by the British Royal Society as the deliberate large-scale manipulation of the planetary environment to counteract anthropogenic, or human-caused, climate change. The United States General Accountability Office has said geoengineering is not an option for mitigation because of cost, effectiveness and potential consequences.

However, some critics have argued that geoengineering may provide the only realistic options for slowing climate change long enough for mitigation efforts to take effect. Proposals have ranged from seeding the upper atmosphere with reflective aerosols to fertilizing ocean plankton to consume more carbon dioxide.

Other lectures in the series include:

  • Nov. 10 - "Who Chooses the 'Right' Climate: ¬†Geoengineering Governance," by Steve Rayner, director of the Institute for Science, Innovation and Society at the University of Oxford. Rayner also directs the Oxford Programme on the Future of Cities. (7 p.m., location TBA)
  • Dec. 8 - "Soaking it Up: Ocean Fertilization to Preserve the Climate," by Richard Lampitt of the National Oceanography Centre in Southampton, United Kingdom. (7 p.m., location TBA)

All events in the series are free and open to the public, with a reception to follow. The series is sponsored by the Oregon Climate Change Research Institute, an Oregon University System institute on the Oregon State campus, and OSU's School of Public Policy. Also supporting the series are the University of Oregon and Portland State University.
