We are told that we are sinning (by emitting CO2), that we have original sin (human greed), which has banished us from Eden (the pre-industrial world), for which we must confess (by condemning irresponsible consumerism), atone (by paying carbon taxes), repent (insisting that politicians pay lip service to climate-change alarm), and seek salvation (sustainability). The wealthy can buy indulgences (carbon offsets) so as to keep flying their private jets, but none must depart from faith (in carbon dioxide) as set out in scripture (the reports of the Intergovernmental Panel on Climate Change). It is the duty of all to condemn heretics (the 'deniers'), venerate saints (Al Gore), heed the prophets (of the IPCC). If we do not, then surely Judgement Day will find us out (with irreversible tipping points), when we will feel the fires of hell (future heatwaves) and experience divine wrath (worsening storms). Fortunately, God has sent us a sign of the sacrifice we must make - I have sometimes been struck by the way a wind farm looks like Golgotha.
