Summary

First up on the podcast, when will the world hit peak carbon emissions? It’s not an easy question to answer because emissions cannot be directly measured in real time. Instead, there are proxies, satellite measures, and many, many calculations. Staff Writer Paul Voosen joins host Sarah Crespi to discuss how close we are to the top of carbon mountain and the tough road to come after the peak passes. Vani Rajendran, senior researcher in the cognitive neuroscience department at the National Autonomous University of Mexico’s Institute of Cellular Physiology, talks about macaques that can keep the beat. She explains how this intriguing ability challenges a long-standing view that animals with complex vocalizations and rhythm are inextricably linked.
