Collective action has worked in the past. We did it with CFCs.

Sort of, mostly. It's an interesting case you bring up, and I think it may be informative about the conditions under which global-scale coordination happens. Note here though, that "collective action" meant government regulating CFCs out of use, and not a bottom-up people movement.

I need to study the details of this case more; from the little knowledge I have on it, the cynic in me would conclude that it only worked as effectively as it did because by the time of the Montreal Protocol, DuPont had figured out and patented a replacement for CFCs.

Side note:

There is a quite recent amendment to the Montreal treaty, the Kigali amendment (2016), which phased out the CFC replacements with strong greenhouse effects in favour of replacements without them. This alone will save us ~0.3° warming until 2100 (if the projections are right).

This is about the only positive news I've ever seen for this topic.

(I really love those charts.)

We're talking many, many orders of magnitude difference in change.
