The "you" in my comment is intended at country level. It basically means: your elected representatives. It's true that individual actions to help the climate may not help a lot, immediately and in practical terms, if there's no bigger policy movement. Then again, seeing that people are willing to take costly individual actions is a strong signal to elected representatives that their electors care about this stuff. So it still may not be worthless.
