Climate change is a red herring, air pollution is a clear and present danger. India and China have ignored this in the past and now they are making some efforts to correct course because people are dying from it.
Air pollution is a big problem. The biggest problem IMO is water and soil pollution. We're putting far worse chemicals into our food and water (and in household products we absorb) than what we're putting into the air (in the developed world, anyway).
True, it's a fact. But what's not a fact, that CO2 is the reason for that. We humans can do nothing about it. How do you else explain some ice age with 10x the CO2 amount in the far past. But don't misunderstand that I am against a cleaner future. Efficiency should be always improved, in every field. But I am against unnecessary change just because of CO2. For example it's better for the environment to use your old car as long as possible instead building new electric cars. This is less efficient overall than repairing and maintaining the tech of today. The whole climate change topic is far more political than actually fact based.
