„Establishing a serious, large-scale research program into albedo modification would have substantial social and political effects, even if it never led to any actual modification. It’s time for the “more research” crowd to at least acknowledge that.“
„Geoengineering has many risks, and we don’t yet know the CIA’s intentions. But given the lack of political will on climate change, we have to look at it“

„Most analyses assume, for example, that SRM would be used to stop the increase in global temperature or restore temperature to pre-industrial values. We argue that these are poor scenario choices on which to base policy-relevant judgements about SRM.“

„Exploring these experiments illustrates the varying degrees to which scientists have wrestled with the ethical, social and environmental governance concerns that have been raised by many. Exploring how these past outdoor research projects were carried out (or not, as is the case with SPICE) highlights the need for existing governance to be adapted to ensure that these concerns are addressed.“
„On February 10, The National Research Council wing of the United States[nbsp]National Academies[nbsp]of Sciences[nbsp]released two reports,[nbsp]Climate Intervention: Carbon Dioxide Removal and Reliable[nbsp]Sequestration, and[nbsp]Climate Intervention: Reflecting Sunlight to Cool Earth (you can find our handy roundup of media coverage of the reports here, our roundup of civil society responses[nbsp]here, and if you have coffee and time at hand, you can find the reports themselves in full[nbsp]here).“
„At the same time, medicare for the environment is, however unwittingly on the part of the Liberals, a genius idea in one respect: both medicare and our environmental laws must transition from being reactive to being proactive and preventative. But that requires an appetite to rebuild from the ground up.“
„At the forefront of this research is David W. Keith, Gordon McKay Professor of Applied Physics and Professor of Public Policy at Harvard University and president of Carbon Engineering, a Calgary-based technology company developing methods to capture and sequester carbon dioxide. I spoke with him in advance of his February 17th talk at The Long Now Foundation in San Francisco.“
„We learned that we’re entering an age of mega-droughts in the American Southwest and Great Plains (see the story by Darryl Fears). There was much talk about geoengineering — see my story from a week ago — and why it’s not a plausible fix for the climate problem (good story by the Merc’s Lisa Krieger, noting that there were anti-geoengineering protesters outside).“
