It’s exactly two years to the day since the nations of the world signed the Paris climate accord to limit man-made temperature rises to two degrees celsius. It’s an agreement Donald Trump has said the USA would now duck out of.
So step forward Emmanuel Macron. France’s President has looked beyond politics to host a summit with some of the biggest beasts of global business, and seemingly with some success. It means that Mr Macron finds himself centre stage on global warming now the United States has vacated it.
