I honestly do not understand those who would vote against this. There is proof it exists and over 90% of scientists agree that humans are contributing. Even if part of it is caused by natural changes, we can do things that protect our cities from rising waters and keep the air breathable. The change will cause such massive changes to our planet that the human race will be gone in a relatively short time. I won't care, but my great grandchildren will! Spending money on this will keep people employed in decent paying jobs. All the military in the world will not help us if we are dead. Let's spend the money on things that will help all of us.
