The human race is doomed, and it's all our own fault. With the quantity of carbon in our atmosphere now well beyond the safe limit, it's almost certain the planet's temperature will continue to rise. Climate change is causing natural disasters of biblical proportions; a situation that's only going to get worse as time progresses. We all need to work harder to improve this situation by using less energy and behaving more responsibly. But since some people will never be convinced the Earth's rapidly approaching the end of its humanity-hospitable era, we're now in dire need of alternative options to save us from ourselves. To help get the word out, we've compiled a list of some of the most exciting scientific projects we've seen of late that could, if successful, undo some or all of the damage we've caused.
