It is widely expected that Justin Welby, having now screwed the crown on Charles III’s head, will shortly retire as Archbishop of Canterbury and put himself out to grass. If so, he is not going quietly. This afternoon, in the House of Lords, he launched a wholesale attack on the government’s Illegal Migration Bill, which includes measures to offshore the processing of asylum-seekers in Rwanda, describing it as ‘isolationist, morally unacceptable and politically impractical’ to leave developing countries to handle the world’s refugees.
But one comment in particular stands out in the Archbishop’s speech. He asserted that ‘the IPCC forecasts that climate change by itself, let alone the conflicts it is causing, will lead to at least 800 million more refugees a year – in total – by 2050’.
It is an extraordinary claim, but is there any truth in it? If the Archbishop was trying to say that 800 million people would be displaced by climate change every year that would mean one in ten of the world’s population having to do a runner every single year.
