What position should the distant observer take on the COP28 conference in Dubai? That the sight of 70,000 delegates flying into a desert oil state from around the world to discuss human impacts on climate change is beyond satire and that its proceedings are never likely to rise above Greta Thunberg’s encapsulation of all such jamborees as ‘blah blah blah’? Or that the climate problem is now so obvious and urgent that all efforts towards global action, however small, should be uncynically applauded?

I leave that choice on the table.
