Removing carbon from the atmosphere will be necessary to avoid catastrophic tipping points, one of the world's leading scientists has warned, as even in the best-case scenario the world will heat by about 1.7C. Johan Rockstrom of the Potsdam Institute for Climate Impact Research, who is one of the chief scientific advisers to the UN and the Cop30 presidency, said 10bn tonnes of carbon dioxide needed to be removed from the air every year even to limit global heating to 1.7C (3.1F) above preindustrial levels.

Let's recognise our failure, he told the Guardian and Amazon-based news organisation Sumauma. The truth is that we have failed to avoid an overshooting above 1.5C in the next few years. And that going above 1.5C has devastating consequences. Some of these devastating consequences are tipping points, be it in the Amazon, be it in Greenland, or western Antarctica or the coral reefs. He said the priority at Cop30 was to shift direction:
