TIL what Americans think about climate change
25/02/2021 Duration: 13minSurveys show that both left- and right-leaning Americans support policies that slow climate change. So why aren’t we seeing more of these policies pass as legislation? In this episode of TILclimate (Today I Learned: Climate), MIT alum Parrish Bergquist joins host Laur Hesse Fisher to explain the significance of public opinion and climate change: what people believe, what influences their opinion and how policies are implemented. They also explore what bipartisan policy making could look like, and how to bridge the gap between support and action.Parrish Bergquist, an MIT alum from the School of Humanities, Arts, and Social Science and the Department of Urban Studies and Planning, is an Assistant Professor at Georgetown University’s McCourt School of Public Policy.For a deeper dive and additional resources related to this episode, visit: https://climate.mit.edu/podcasts/til-what-americans-think-about-climate-change.

TIL about uncertainty
10/04/2019 Duration: 10minHow do we make choices in the face of uncertainty? In this episode of TILclimate (Today I Learned: Climate), MIT professor Kerry Emanuel joins host Laur Hesse Fisher to talk about climate risk. Together, they break down why the climate system is so hard to predict, what exactly scientists mean when they talk about “uncertainty”, and how scientists quantify and assess the risks associated with climate change. Although this uncertainty shrinks every day — as researchers refine their work, computing power grows, and models improve — what we do and how quickly we act will ultimately come down to how much risk we are willing to accept. Kerry Emanuel is an MIT Professor of Atmospheric Sciences and the co-founder and co-director of the MIT Lorenz Center. In 2006, he was included in Time Magazine’s “100 People who Shape Our World”.

In this episode of #TILclimate (Today I Learned: Climate), MIT professor Kerry Emanuel joins host Laur Hesse Fisher to break down how these “heat engines” work and how a changing climate will increase hurricane intensity, storm surges, and flooding. They also explore how people around the world are adapting to growing hurricane risks. Prof. Emanuel is the Cecil & Ida Green Professor of Atmospheric Science at the MIT Department of Earth, Atmospheric and Planetary Sciences and co-director of the MIT Lorenz Center.
