Explaining COP21 Climate Agreement

12-16-15 During this hour I guest host "The Leslie Marshall Show." I'm joined by Bob Deans, director of strategic engagement for the National Resources Defense Coucil (NRDC). Bob helps to breakdown the details of this past weekend's historic Climate Agreement reached by nearly 200 countries. The goals of the agreement are to tackle the threat of climate change and accelerate the shift to clean energy around the world. Bob also explains why the move towards clean energy is not only good for the climate, but also presents huge economic opportunities for America and for the world. The NRDC's Twitter handle is @NRDC.
