Just started listening to their podcast recently and it's super good. Great chemistry between the hosts and they have good comedy chops in addition to being knowledgeable about what they're talking about.
https://www.youtube.com/channel/UCxG5KAao5rJY3vvwbVUSv4g - The "This Is CDR" series is particularly good.

In the long run, CDR is no less vital than decarbonizing.
I'm going to recommend Climate Change with Katharine Hayhoe, though in general, I find that video is a terrible way to encounter content if you want to be able to think critically about it.
