Agreed. The question though is how to do that. Or more importantly what is the right implementation.
The video I linked personally I think is good, it keeps the money aspect within the control of each country and citizens will benefit and it could be implemented globally.
The way it was set up before, was countries pay into some giant fund where some un-elected officials get to carve up who gets what. A recipe for corruption. Which for Trump coming in after Obama, who had set up agencies to be his slush fund to dish out to his favorite causes(see below) might be skeptical the money is used to combat Climate change.
The irony of that agency, by the way was it was the brain child of Elizabeth Warren and was setup with no Congressional oversight. Deliberately of course, because they planned shady shit. Just like Sally Yates told the Inspector General that Bruce Ohr’s division of DOJ was off limits, just as he is about to pull some shady shit and they have you guys screaming about Orange man Bad. These politicians (and I mean this of all of them with very few exceptions, both left and right) are absolute weasels.
