Today’s episode answers all your big climate science questions. Alex chats with Zeke Hausfather, Breakthrough’s new Director of Climate and Energy, who joins us with over a decade of experience working as a scientist and researcher in the clean tech sector, Berkeley Earth, Project Drawdown, and Carbon Brief. They talk about the real-world difference between 1.5° and 2° warming (and 3°, and 4°…), the easiest sectors to decarbonize (and how), whether scientific uncertainty changes the kinds of solutions we should pursue, and, finally: how are we actually doing?
