Methane is a potent greenhouse gas that traps more than 80 times as much heat than carbon dioxide over a 20-year period and causes 25% of global heating today. We definitely don’t want this gas spewing needlessly into the atmosphere, but in 2023 that’s exactly what environment editor Damian Carrington found was happening when he reported on 1,000 super-emitting methane leaks across the globe. Now Turkmenistan, the worst country for mega-leaks, has begun to plug them. Damian tells Madeleine Finlay why some experts call stopping leaks the climate ‘emergency brake’ and reveals which countries are still failing to act.

Sea ice is melting fast and worsening the climate crisis. But what if there were a way to thicken it again? Madeleine Finlay is joined by environment editor Damian Carrington to discuss a bold attempt to refreeze the Arctic which is showing early signs of success. He visited the project to find out how it will work, how much it will cost and whether it really has potential to improve the fate of the Arctic’s ice
