Donald Trump once advocated for climate action. Now, he’s moving Barack Obama’s efforts in the opposite direction. Obama’s former science advisor, John Holdren, talks about the damage being done by today’s White House. For twenty years, Jerry Taylor ran the energy and climate programs for conservative organizations funded by the Koch brothers, before coming around on climate change. He recounts his journey, going from a climate denier to a climate mainstreamer. On this episode of Climate One, Holdren and Taylor join Greg to talk about climate science and politics. John Holdren, Former science advisor to President Obama; Professor of Environmental Policy at the Kennedy School of Government Jerry Taylor, President and Founder, Niskanen Center This program was recorded at the Commonwealth Club in San Francisco, CA in December, 2017.
