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 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.
