How 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”. Through his decades of experience studying the atmosphere and earth’s climate, Prof. Emanuel focuses on trying to quantify the risks of these anthropogenic (human-caused) changes, especially focusing on hurricanes.
