My objection is with the commonly held position that the solution to climate change is to "Sit back, relax, and Vote Democrat." That seems pretty well likely to end up in the same spot as "Doing nothing."
It's actually much more effective than expending energy obsessing about how much carbon you're emitting on a daily basis. Use that energy instead to vote/support/campaign for Democrats, because the marginal utility of having more Democrats in power is exponentially more important, given the consequences of not having them in power.
Use the energy to persuade your representatives to actually do something (including by raising awareness among your fellow voters) rather than voting for a particular party. Of course, Democrats are more likely to be persuaded, but "sit back and vote for Democrats because it's better than <shitty alternatives>" is a pretty surefire way to lose the climate war.
