Climate change? Really? Defeating climate change? All the money spent pursuing the fix (to move the needle a blip) would be better spent addressing actions to cope with the change, as well as world diseases, providing clean drinking water, helping the hungry. Take all the humans off the Earth and you will still have climate change. Has human activity been the smoking gun for climate change? You must think so, if you also believe human solutions can stop it. Better get busy dealing with it rather than trying to stop it. Reducing pollution in and of itself is a just and noble enough goal, and doesn't need to be saddled to saving the world from global warming.
