This Earth Day, we wanted to bring together a group of science communicators to unpack the current moment in the 'climate emergency.' On today's show, Laura Helmuth, editor-in-chief of Scientific American, Asmeret Asefaw Berhe, professor and chair in Earth Sciences, Life & Environmental Sciences Department at the University of California-Merced, and Sir David King, founder and chair of the Centre for Climate Repair, talk about the climate emergency we're living in, and where we go from here.
