Yesterday was a “National Day of Action” on Climate Change. At least 40 U.S. cities participated in protests and events geared to push lawmakers to act more aggressively on the Environment and sustainability. Ken Kimmell, president of the Union of Concerned Scientists, attended last year’s climate march in New York. He was also present when President Obama unveiled his Clean Power Plan this past August. Kimmell will join us to discuss the progress of the ‘National Day of Action’, his thoughts on President Obama’s energy plan and what he hopes is accomplished at the December climate talks in Paris.
