This week, the team talk positive tipping points, grapple with the comms coming out of the pre-COP meets and send our tributes to dearly loved colleagues who have recently passed.  With pre COP 28 meetings currently taking place, the host team discuss the mixed messaging that is currently making headlines and anticipate what this might mean for how the future of fossil fuels will appear in the final text at COP 28.  Tim Lenton, the founding Director of the Global Systems Institute at the University of Exeter and Chair in Climate Change and Earth System Science is our guest this week, and with Tom unable to make the interview, our brilliant colleague from Global Optimism, Freya Newman, joins Christiana and Paul to interview her former professor. With negative tipping points racing along their own ‘S curve’, the team ask Tim Lenton whether there are signs that the positive tipping points can win this race and avert the worst impacts of the climate crisis (pssst, the answer is it looks very, very possible).  Music this week comes from Jemima Coulter with their beautiful song ‘[flowers]’.
