[@j8cob] As hype as I can get about futuristic stuff, it's still very likely climate change will ruin the Earth before we find anything worthwhile in space. Besides, why can't we just do both? It's not like they're mutually exclusive, heck - they both serve the betterment and long-term survival of humanity. Which is as much of an 'ultimate goal' as it can get, isn't it?

Climate change is a multifaceted force that we have little control over. For the vast majority of the Earth's existence, the climate has been determined more by the activity of the sun than of the organisms or geological processes of the planet. To say that humanity is the cause of climate change is absurd and ignorant of the facts. I would be more concerned with growing pollutants from developing nations rather than small variations in the climate and temperature of the earth.
