When climate change threatens national security

The impacts of climate change are becoming not just unignorable, but unbearable. Yet the political consensus around climate action is fracturing, as leaders debate the speed and scale of the changes needed. This week on *Zero*, Akshat Rathi speaks with Caroline Lucas, the former head of the UK’s Green party and a member of parliament for 14 years, about the increasing threat climate change poses to national security, and what she’s learned from four decades at the frontline of climate politics.   **Explore further:** - Caroline’s series for The Rest Is Politics - Zack Polanski on Zero - Dale Vince on Zero - Lieutenant General Richard Nugee on Zero *Zero* is a production of *Bloomberg Green*.
