Science Won't Save Us

I keep hearing polaticians encuraging more spending in science to combat climate change. I think this is good because I love science, but science already has a silver bullet solution and that is Nuclear Fusion, but as Steven Cowley explains in his Ted Talk, it will be at least until 2030+ before we know how to do it properly. If we wait until that time the planet will be well into a state of rejecting us. So we need to use the techniques we have now to do as much as we can.
