> It's not at all about individual action. This scale of problem requires policy intervention and investment at national levels, and inter-governmental coordination internationally.

It is all about individual action. And then the emergence from that to what amounts to the multi-pronged solutions that are needed to address a wicked problem. Like create the "big meaningful wins" you mention. There is no mailbox where you drop off "stop the use of coal", and it happens, neither is there a magic button. A complicating factor is that we are not able to see how our small individual actions contribute to solving the wicked problems, and we are not able to coordinate them at scale.
