À quel point le Monde est-il proche d’un changement climatique irréversible ? Les points de basculement critiques du système climatique sont les ombres au tableau lorsqu’il s’agit…

Critical tipping points in the climate system are the flies in the ointment when it comes to accurate prediction of where our planet is headed

In his Cop27 speech this week, our will-he-go, won’t-he-go prime minister said that stopping the planet dangerously overheating was still within our grasp, leaving many wondering just what planet he was on. According to Rishi Sunak, last year’s Cop26 climate conference in Glasgow was all about keeping alive the possibility of preventing the global average temperature rise since the Industrial Revolution from climbing above 1.5C. That is “alive”, as in connected to a drip, in a coma and suffering cardiac arrest every few hours.

While more extreme threats are unlikely to be realised, sticking to the precautionary principle is just plain common sense. A middle of the road route would be to no one’s advantage – so, as for most situations wherein the risk is hard to quantify, there is only one sensible way forward: to hope for the best, while preparing for the worst.
