Paul Solman interviews Climate Shock authors Martin L. Weitzman and Gernot Wagner on what it’s described as "economic tactics to hedge against the risks of climate change". Mainly through a price on carbon via a 'carbon tax'.
The segment then moves to Solar Radiation Management with an interview of physicist and entrepreneur David Keith.
There is also a short blurb and an extended interview at the PBS NewsHour blog:
A cheap but dangerous global warming fix
By David Keith - July 16, 2015
Highly interesting.Unfortunately even though Keith raises some of the concerns surrounding the issue of GeoE, there is no real counterpoint to this segment. I would have loved to hear the points of view from some of (who I think are) the strongest geoengineering critics like Naomi Klein, and other interesting takes perhaps like Braden R. Allenby and others with more impartial views on the subject.(O.E)
