On 11 February, more than 250 people joined me for an online discussion on the findings of Collision Course, the latest report by the Breakthrough National Centre for Climate Restoration. The event was part of the National Sustainability Festival 2025.
The event unpacked the stark realities of a world shaped by 3 degrees of global warming, and offered a stark examination of the profound risks to humanity, ecosystems, and the foundations of global stability.
As the planet approaches unprecedented climate thresholds, the risks intensify—not only for extreme weather events but for cascading systems failures that threaten food security, infrastructure, health, and geopolitical stability. Collision Course delves into the interconnected challenges of such a future and asks the pressing questions:
- What does life look like under 3 degrees of warming?
- How close are we to these scenarios, and what are the tipping points to avoid?
- Most critically, what actions can still be taken to alter this trajectory?
The forum shed light on the accelerating climate risks and the bold, systemic transformations required to restore a safe climate. Combining scientific insight, policy critique, and an emphasis on actionable solutions, the event aimed to inspire a deeper understanding of humanity’s climate future and catalyze the urgent changes needed to ensure safety and stability.
