Scientists working for oil giant Exxon between 1977 and 2003 accurately predicted the pace and scale of climate change and warned of the harm of burning fossil fuels, while firm’s executives played down the risk. Now Exxon’s quantitative climate projections have been assessed for the first time. On this special episode of the podcast, host Rowan Hooper discusses the Exxon science with New Scientist environment reporter Madeleine Cuff, and climate scientist Peter Stott. Peter is the author of Hot Air, The Inside Story of the Battle Against Climate Change Denial and is a specialist in climate attribution at the UK Met Office’s Hadley Centre. There is also a contribution from climate scientist Michael Mann.The panel discuss ExxonMobil’s response to the new study, and talk about what we can take from it in terms of not being beguiled by vested interests when pushing for a fast transition to a world free from fossil fuels.The team also reacts to the news that the head of one of the world's biggest oil companies will be president of the COP28 climate summit later this year.To read about these subjects and much more, you can subscribe to New Scientist magazine at newscientist.com.

There’s been an exciting breakthrough in nuclear fusion. For the first time on Earth, a controlled fusion reaction has generated more power than it requires to run, bringing us closer than ever before to a viable way of producing clean energy for the world. So, what’s the catch? The team finds out.The New Scientist team reports from a worryingly quiet COP15. It’s hoped the biodiversity conference will be an opportunity to set ambitious global goals for nature, to reach the goal of restoring it by 2030. But with a distinct lack of world leaders in attendance, can this vital conference deliver?We now know how to spot alien spacecraft whizzing through space at warp speed…assuming some advanced civilisation has figured out how to stretch the fabric of spacetime of course. The team finds out about this new research which involves LIGO and gravitational waves.Shakespeare lived through an intense period of deforestation and climate change, and he referenced a lot of this in his work. Think back to Titania’s speech in “A Midsummer Night’s Dream” about the changing seasons, and when Gloucester in Henry IV part 2 says “the seasons have changed their manners”. Shakespeare even described the energy transition from wood to coal as a fuel source. Rowan chats with Shakespearean scholar Randall Martin from the University of New Brunswick in Canada, and auditions for the part of Queen of the Fairies.Acclaimed science fiction author Adrian Tchaikovsky discusses his latest book, Children of Memory, the story of a fragile human colony on a far flung outpost – and some corvids, which may or may not be sentient. On the pod are Rowan Hooper, Penny Sarchet, Matt Sparkes, Madeleine Cuff, James Dinneen and Alison Flood.

An extinct species of ancient human may have been much more advanced than we first realised. First discovered 10 years ago, Homo neladi had a brain about a third the size of ours and yet it may have done complex things like burying its dead and controlling fire. The team learns about the latest finding from the Rising Star cave near Johannesburg.Mars has long been described as geologically dead, but new evidence shows it may still be volcanically active. The team learns about a new theory which might explain what created the mysterious trenches in the Cerberus Fossae region of the planet.The largest complete map of the connections between neurons inside a brain has been made - but it’s not of a human brain. This whole-brain connectome is that of a Drosophila larva - the larva of a fruit fly. The team finds out about this massive undertaking - a stepping stone to describing the brains of more complex animals.Are penguins self-aware? When we try to answer this question in any animal, we tend to use the controversial mirror method - and that’s exactly what a group of researchers have done. But does it actually work, and can we trust the new findings? The remains of the last known thylacine (Tasmanian tiger) have been found, 80 years after they went missing. Self-described Australian mammal nerd Jack Ashby of Cambridge University tells the team how this curious mystery was solved.
