Internationally coordinated research and field-testing on ‘geoengineering’ the planet’s atmosphere to limit risk of climate change should begin soon along with building international governance of the technology, say scientists from the University of Calgary and the United States.
Collaborative and government-supported studies on solar-radiation management, a form of geo-engineering, would reduce the risk of nations’ unilateral experiments and help identify technologies with the least risk, says U of C scientist David Keith, in an article published in the Jan. 27 online edition of Nature. Co-authors of the opinion piece are Edward Parson at the University of Michigan and Granger Morgan at Carnegie Mellon University.
“Solar-radiation management may be the only human response that can fend off rapid and high-consequence climate change impacts. The risks of not doing research outweigh the risks of doing it,” says Keith, director of the Institute for Sustainable Energy, Environment and Economy’s energy and environmental systems group and a professor in the Schulich School of Engineering.
