My personal theory is that modern leaders of the church, most especially in Europe, have Stockholm Syndrome. Increasingly, people in the west have no religious faith to speak of, but many have developed a loose system of ethics and morality with environmentalism at its center. Belief in its tenets, chiefly AGW, confers status as a "good person", understanding the issue thoroughly is discouraged, and being atop the decision making related to it confers king-like power. This reminds prelates of the good old days, and they'll ride on those coattails if its not expressly against their doctrine.
Access to energy influences human flourishing far more than the climate that will change with or without our fealty to the wind and sun. You can't have clean water, modern agriculture, sanitary cities or productive industry without affordable and reliable energy. The AGW crowd is focused on making energy production less reliable and more expensive to the benefit of their friends. That's not moral in my book, but I'm no theologian.
Responsible stewardship of the earth is one thing, assuming that no impact from human activity is ipso facto the best way to go is a scam and anti-human.
