An interesting article in the FT by Tim Harford, Saving the planet demands sacrifices just as Covid-19 does (arch), which links Covid and GW more usefully than previous attempts. The best line I think is The pandemic is giving us a taste of what an end to growth might look like. Which is aimed at the many environmentalists [who] nod along with Greta Thunberg’s sentiment about “fairy tales of eternal economic growth”. You can weasel about this as "of course this wasn't planned and it would be better if we planned it" but I don't believe that - apart from anything else, Covid shows how poor any central planning attempt is likely to be. As to the actual question, see my How much would we have to adjust our lifestyle to stop global warming?
As you see from my pic, the premature eternal summer is over. In other news, my cat has an Instagram account. And it rather appears that some people need to read stuff like Price Signals, Price Gouging, and Philanthropy.
