Reasons to Be Cheerful?

Justin Welby, the current Archbishop of Canterbury, is the Church of England's most senior cleric. He is also a member of the UK's House of Lords. In his 2022 New Year message, Welby opined that the public 'should not despair over the climate crisis' (https://www.theguardian.com/uk-news/2022/jan/01/real-reasons-to-hope-on-climate-action-says-archbishop-of-canterbury). Welby said (like his fellow Etonian, the PM) that there were real reasons to hope (for a solution to global heating) post Cop26. Isn't this essentially what the major petrochemical companies have been feeding the public for decades? Before he became a priest, Welby spent 5 years working for Elf Aquataine (a French oil company).
