Environmentalism, notionally, is trying to solve problems. The air was dirty. We solved that. Water was dirty. We solved that. Problems got more esoteric and ill defined with problems like acid rain and CFCs, but we seemingly solved those purported problems. The key was intractability. The environmentalists and those who saw the movement as a means to power needed an unsolvable problem. Telling humans their use of energy is the problem provides an unsolvable problem. Thus was born the notion of carbon dioxide causing climate change. The eternal problem for the unending alarm. There is your politics. There is your will to power. That is why climate alarmism will still be a thing generations from now when the world moves along in spite of it.
