The EPA was not authorized to do anything they wanted. The clean air act only authorized the EPA to regulate pollution, not climate change. What part of that do you not understand? It's the reason SCOTUS ruled the EPA's regulating CO2 is unconstitutional. You are nothing more than a political animal. Your science is controlled by politics. Just like the IPCC.It's entirely possible for what we think and what we type out here to be different. I am now going to assume that you agree that the EPA was constitutionally created and authorized by Congress.
