If you believe that the coordination problem required to prevent global climate change is intractable (how are we going to make Russia stop burning oil? Nigeria? Pakistan?), then taking steps to ensure that your country comes out of that alive makes sense. Or at least makes sense if you value people in the relatively standard human order (self ~ close family > far family > community > region > country > everyone else) - some people might have different steps in there, but it's almost always going to end with members of some in group being worth more than people not in that group. And if you say "but I'm not like that! I care about everyone equally!", then that's nice, but I don't believe you. (unless you're the kind of person who gives a large portion of their income to 3rd world charities - and I mean 50%+ there. Otherwise, aren't you demonstrating that you care about yourself more than random 3rd world children you've never met?)
