An interview with David Keith, an award winning professor of Applied physics at Harvard University where he is leading an interdisciplinary research team who is researching global-scale geoengineering strategies to mitigate climate change, primarily stratospheric albedo modification. Keith is also a Professor of Public Policy in the Harvard Kennedy School.

We start with discussing Keith’s research, which aims to reduce global temperatures through increasing the albedo of the stratosphere — reflecting more solar radiation back into space. Along with the risks and benefits his team is investigating, Keith also points out that none of this research has left the lab setting.

In the second part of the show, we talk about the so-called “chemtrails” conspiracy theory which includes Keith’s research being a part of a super secretive global scale program of some sort or another, and has led in real life to threats, vitriol, and slander being directed at the scientist.
