Extinction Rebellion’s co-founder Clare Farrell and conservation scientist Dr Charlie Gardner team up once more to discuss issues and stories they feel are not getting enough airtime. They want to make sure that the latest news in science and important reports that are relevant to the climate and ecological crisis are flagged and explained in ways that are easy to understand.

EPISODE 29: CO2 accelerating, corals gone forever, is it time to start geoengineering?

In this episode Charlie explains the recent measurement of accelerating atmospheric CO2 concentrations in the atmosphere as well as the announcement that coral bleaching has passed a tipping point, while Clare delves into the world of solar radiation management at a recent conference she attended with James Hansen.

EPISODE 28: Tipping points, conservative models and will climate shocks cause people to rise up?

In this episode, Clare and Charlie discuss the recent heatwaves that have hit Europe this summer; can we adapt, and will it trigger a mass uprising? They also talk about the latest research into climate tipping points, both good and bad, and how some climate models may be underpredicting climate risks.

EPISODE 27: International judges back climate justice, the cost of decarbonisation, and narrative wars

In this episode Clare and Charlie discuss the recent ICJ ruling on the obligations of states, the new OBR Fiscal Risks and Sustainability report, the role of narrative framings in the climate culture war, and Clare's recent trip to Lorentz to workshop strategy.
