MIT Sloan’s John Sterman took data-based models to the 2015 Paris Climate Conference. The Systems Dynamics professor used data-based models to build consensus around curbing greenhouse gas emissions and limiting global temperature rise. Recently, President Trump announced that the US is withdrawing from the Paris Climate Accord.

We speak with John about how data-based models can change minds and spur action, and why he's still hopeful about the future of climate change. You can learn more about John's work on climate change at http://climateinteractive.org.
