Of course, one of the things James doesn’t mention is with probable European economic collapse no-one will be able to afford Climate Change mitigation, whether the problem is real or not. Not that it is real. If increasing CO2 had the warming effect as predicted, the trends would be clear by now and they aren’t.
There is another irony. As he rightly points out, only rich societies can afford to clean up rivers etc. Cut economic growth, collapse the system, and guess what? The Earth will become a less pleasant place, and all the Environmental improvements made over the past thirty years (Cleaner air, water and so on) will go into reverse. Simply because it will become uneconomic to clean up the mess.
Rather like burning houses down in Uganda to make way for plantations of non-native species selected for ‘CO2 mitigation’. Oh tempera, oh mores.
