It would be completely counterproductive. One of the biggest problems with Climate Change is that it requires mass collective action, and that requires a stable and rational government or organize. Were climate change activists to promote anarchy it would be impossible for them to achieve their goals.
For most young Westerners who have never known anything but rule of law, that’s probably difficult to imagine.
One scenario I've heard, and has me a bit worried, is climate crisis begets a right wing reactionary environmentalism. Basically all the same nativist, anti-immigration, isolationist, anti-trade, yadda yadda, but with an "environmental" justification.
So instead of mitigating or undoing the damage, the reactionaries would be energized by protecting what we have from "the other".
Not too hard to imagine a crackdown, if scarcity leads to hunger leads to unrest.
Yes, it won't be seamless, but we can adjust to new conditions.
