Look, let’s get rid of the notion that we need everyone to agree to fix this (or any) problem. We don’t. In all of history, the people worldwide have never united. Yet, people have accomplished things, often big things, without everyone on board.
So, let’s ignore those who won’t help and join with those who will. Let’s defy any rules or systems or laws or norms that are contributing to climate destruction. Let’s do all we can to empower climate scientists and engineers and everyone who does actual work (that leaves out politicians and “business leaders”, whatever they are) and who actually CARE ABOUT THEIR CHILDREN AND THE FUTURE to do whatever is necessary to keep our species alive.
