Health Warning: The Human Cost of Climate Inaction with Julia Gillard

Scientists warn that the world could breach its 1.5°C emissions limit within just 2-3 years. It’s a scary thought, but across the globe, many are grappling with an even more immediate and visceral reality: the climate crisis is already a health crisis.

From deadly heatwaves to worsening air pollution and climate-related trauma, the health impacts of climate change are escalating. In this episode, Christiana Figueres and Paul Dickinson explore how growing awareness of these challenges is beginning to reframe the conversation, and ask whether this could be the narrative that finally drives faster, more inclusive climate action.

Christiana is joined by former Australian Prime Minister and Chair of the Wellcome Trust, Julia Gillard, who makes the case for why health must become central to climate communication - and why we should be talking about “lives lost”, rather than simply degrees gained.

Meanwhile, Tom Rivett-Carnac drops in from the launch of London Climate Action Week 2025, where health is rapidly emerging as a defining lens.
