How Did Climate Engineering Research Emerge?
Some propositions for intentionally changing the global climate have existed for decades. However, the last decade has seen an unprecedented proliferation of scientific study along with the creation of dedicated research programs to gauge the physical and social effects of removing greenhouse gases from the atmosphere and reflecting sunlight back into space. Scientific work has been accompanied by increased attention from the media, public intellectuals, and environmental and technology watchdog groups. Government-commissioned assessment reports have been released by the UK, the US, and Germany. International governance frameworks for field research are being created at the Convention on Biological Diversity and the London Convention and Protocol. The Intergovernmental Panel on Climate Change has substantially expanded its discussion of climate engineering in its fifth assessment report, compared to earlier reports.
