The Church has now decided that global warming can serve the same purpose for them as it does for the Green lobby: serving as an opportunity for its elites to be smugly sanctimonious and preach upon us unwashed evil-doers (while often being the worst "sinners"). A Bishop has declared that flying is a sin.
Well alright. If global warming is the apocalypse caused by our straying from the path of righteousness then surely anything contributing to the wrath of the deity must be a sin.
Michael Portillo agreed last night on This Week. By the same logic opposing nuclear power is also a sin.
