Global warming has been blown way out of proportion. The steep decline in cost of solar panels and wind turbines over the last 10 years is already enough to solve the problem. Oil will simply be more expensive and that's what will trigger change. People vote with their wallets, only a tiny proportion of the population has the luxury of doing anything but. Foolish to try to appeal to morality when most of the world lives paycheck to paycheck or worse. On Mars we actually do want to create global warming and a greenhouse effect, so it's good that we know how :D
