It was hailed by some as a milestone in reducing the carbon footprint of air travel, which accounts for about 2.5% of global CO2 emissions. Could this be the start of a greener way to fly? Madeleine Finlay speaks to Guy Gratton, associate professor of aviation and the environment at Cranfield University, to find out if the future of aviation can ever truly be guilt-free..

Science Weekly revisits episode two of this 2023 mini-series from Full Story. In part two of Weight of the world, three Australian climate scientists reveal the professional and personal toll of their predictions. Lesley Hughes tells us about the axing of Australia’s Climate Commission, a group tasked with educating the public about climate science and the need to cut carbon emissions; Graeme Pearman talks of the pushback from government and industry; and Ove Hoegh-Guldberg speaks of the personal attacks and death threats that followed his warnings. All three express their disbelief that meaningful action didn’t follow the science, with Pearman saying he was ‘naive’ to think it would.

Science Weekly revisits episode one of this 2023 mini-series from Full Story. Pioneering Australian scientists Graeme Pearman, Lesley Hughes and Ove Hoegh-Guldberg saw the climate crisis coming. Pearman predicted the increase of carbon dioxide levels, Hughes foresaw the alarming number of species extinctions and Hoegh-Guldberg forecast the mass coral bleaching events we’re seeing today. All three went on to become some of the country’s most respected experts in their fields, travelling the globe, briefing leaders, and assuming the world would take action having heard their alarming findings. In part one of this three-part series, these climate change scientists reveal the moment they realised the planet was heading for certain catastrophe. What did they do when they found out? How did they think the world would respond? And how do they feel today, looking back on that moment of cognisance?. Help support our independent journalism at theguardian.com/sciencepod
