It's your prerogative to not care. It is essentially a fact that barring some sort of societal sanction, that there isn't any personal benefit in "going green", because there is significant personal downside to doing so but an insignificant personal benefit to the climate. Even if we could argue that a world where everybody reduced their emissions would be better for your self-interest than a world where nobody did, you seem keen on not personally reducing your emissions anyways so long as you aren't forced to in favour of rational self-interest. Potentially one could convince you to favour forcing everybody (yourself included) to reduce emissions, but this seems unlikely when you start off a post with a mocking "the sky is falling!" with a middle of "I drive a large car and keep the heat comfortable" and end it with "convince me". Why would it be in anybodies strategic interest to convincing somebody openly hostile who affirms a minority position? It's more time-efficient to convince other people to use force against parties that you rely on for goods and services, as well as you directly.
