The problem is, Global Warming is still just a theory. It can not be proven in our lifetimes. It’s going to take another 3–4 generations of Humans before there is enough data to make the conclusion. Besides Humans can not be the only cause if it is proven. What about volcano’s? They poof out major amounts of Co². People need to understand we can not punish ourselves over a theory. And the Paris accords the left is so pissed because the US is not going to pay for all of it.
