“The belief in man-made global warming”, observed the climate-change sceptic Christopher Booker recently “has become for many a new religion”. It is undoubtedly the case that those who believe in whatever analysis the International Panel on Climate Change (IPCC) comes up with tend to do so as though this body were infallible (despite the fact that some of its most confident pronouncements have been shown to be false, one or two ludicrously so).  Mr Booker cites in support of his observation a lengthy document published by the Methodist Church, which it is proposing for discussion as official Methodist policy. They decide these things at a conference, it seems; thank the Lord (literally) that the Catholic Church has other means of deciding “official” Catholic belief.
