Last fall, scientist and provocateur David Keith offered one of the most conversation-provoking TEDTalks ever — calmly discussing ideas for geo-engineering our climate that border on shocking (like shooting a cloud of sulphurous particles into the stratosphere to simulate the cooling effects of a major volcanic eruption). It’s a scary subject, but as Keith pointed […]Continue reading
Why you should listen
Environmental scientist David Keith works at the intersection of climate science, way-new energy, and public power. His research has taken him into some far-out realms of geoengineering -- dramatic, cheap, sometimes shocking solutions to a warming atmosphere, such as blowing a Mt. Pinatubo-size cloud of sulfur into the sky to bring the global temperature down.
His other areas of study include the capture and storage of CO2 , the economics and climatic impacts of large-scale wind power , and the use of hydrogen as a transportation fuel. Another interest: How we make decisions when we don't have reliable scholarly data.
He teaches at the University of Calgary, and was named Environmental Scientist of the Year by Canadian Geographic in 2006.

David Keith’s TED talks
Environmental scientist David Keith talks about a cheap, effective, shocking solution to climate change: What if we injected a huge cloud of particles into the atmosphere, to deflect sunlight and heat? As an emergency measure to slow a melting ice cap, it could work. Keith discusses why geo-engineering like this is a good idea, why […]Continue reading
