I've written on that topic multiple times. I wrote a "Climate Change" political ad:
A Climate Change version of the “Daisy” ad
I wrote about visualizing "Climate Change" in terms of the Chicxulub Impact Event.
Here's a piece about how to explain wildfires in terms of ecosystem turnover.
I wrote a piece explicitly about the need for "Climate" memes that could engage people and get them to become "Climate Voters".
So, I totally agree with you on the reality that our climate actions will be insufficient until there is enough popular will to make real action happen. When I wrote about COP26 I wrote about how the easiest course of action for the political leadership is to hope that the invisible hand of the market will solve the problem for them.
Finally, I wrote a political piece about the political/social response I think is going to happen when we do have a "Climate Awakening" and everyone finally understands how bad the Climate Crisis really is. A what happens when it "gets real" for everyone analysis. It's not going to be a happy "come to Jesus" moment.

We will be in a completely different world by the end of this decade. The Climate Shock we are about to experience is going to cause a political shock that will remake our world. By 2030 the only political issue will be the Climate Crisis.
BTW: I read your piece. I thought your statement, "that pessimism and optimism are both irrelevant--we just need the truth" was great.
