The costs and technology needed to reflect the Sun's heat back into space are currently more attainable than other climate intervention ideas like absorbing carbon dioxide (CO 2) from the air. "As scientists, we need to understand and predict the positive and negative effects it could have on the natural world, identify key knowledge gaps, and begin to predict what impacts it may have on terrestrial, marine, and freshwater species and ecosystems if it were adopted in the future." "There is a dearth of knowledge about the effects of climate intervention on ecology," said Zarnetske. The interdisciplinary team is co-led by Phoebe Zarnetske, community ecologist and associate professor in Michigan State University's Department of Integrative Biology and the Ecology, Evolution, and Behavior program, and ecologist Jessica Gurevitch, distinguished professor in the Department of Ecology and Evolution at Stony Brook University.Ĭonversations between Gurevitch and climate scientist Alan Robock, distinguished professor in the Department of Environmental Sciences at Rutgers University, gave rise to the pioneering group, which is more aware than most that geoengineering Earth's atmosphere is more than just a science-fiction scenario. It is a strong reminder of the importance of the need for multi-disciplinary analysis of complex problems in environmental science." "I was unaware that modeling climate intervention was so advanced, and I think that climate modelers were unaware of the complexities of the ecological systems being affected. "Participating in this working group has been quite eye-opening for me," said co-author Peter Groffman, an ecosystem ecologist at the Advanced Science Research Center at The Graduate Center, CUNY and the Cary Institute of Ecosystem Studies. The group's seminal paper, "Potential ecological impacts of climate intervention by reflecting sunlight to cool Earth," was published in the most recent Proceedings of the National Academy of Sciences ( PNAS). Every month since September 2019 the Climate Intervention Biology Working Group, a team of internationally recognized experts in climate science and ecology, has gathered remotely to bring science to bear on that question and the consequences of geoengineering a cooler Earth by reflecting a portion of the sun's radiation away from the planet-a climate intervention strategy known as solar radiation modification (SRM).
