 Hello, I'm Laura Hesse-Fisher of the MIT Environmental Solutions Initiative, and this is Today I Learned Climate. Today, we've brought on a guest to tell us about a way that we could slow climate change, not over the next 100 years, but over the next 10 or 20. One of the unique ways that we could start to change the rate of global warming in our lifetime is actually to target what are called short-lived climate pollutants.
