I don't know if Adreas Malm is operating with a new group or independently or what. But he broke off from Climate Extinction and seems interesting to me. You might want to do some online research and investigate what he's doing now.
I'd like to see multiple approaches and efforts. I don't know which will work—if any. Obviously, I have a belief that the framework in A Climate Declaration is a good one, and plan to stick with that. But I'm a fan of other approaches as well.
