When I first watched this video, I think the first thing that came to mind was how brilliant and simple an idea it was that the planet would have it’s own method to cool itself. Without giving away too much of the video, David Keith points out how volcanoes cool the Earth in a very rapid manner, how we can learn from this and apply it to new scientific methods of short-term global cooling while we continue to struggle to reduce carbon emissions in the long-run.

More importantly, Keith points out the more important aspects of trying to reduce warming on a global scale.
