Collision Course: 3-degrees of warming & humanity’s future

Current policies are failing to effectively reduce emissions, with many governments still relying on fossil fuels.
February 27, 2025

A thought-provoking and vital forum exploring the findings of Collision Course, the latest report by the Breakthrough National Centre for Climate Restoration. This webinar unpacks the stark realities of a world shaped by 3 degrees of global warming, offering a clear-eyed 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?

Summary

The online forum titled “Collision Course: Three Degrees of Global Warming and Humanity’s Future,” hosted by Emily Rice, focuses on the urgent implications of climate change. The discussion centers around the findings from the latest report by Breakthrough, an Australian think tank dedicated to climate restoration. The report emphasizes that current climate pathways are inadequate and that the trajectory towards three degrees of global warming poses severe risks to humanity and ecosystems. David Spratt, the research director at Breakthrough, outlines ten critical points from the report, underscoring the rapid acceleration of global warming, the occurrence of extreme climate events, and the crossing of tipping points in the climate system. The conversation highlights the need for immediate action to avert catastrophic climate scenarios and discusses the political implications of climate inaction.

Highlights

  • 🌍 Urgent Conference: The forum addresses the critical implications of climate change and the findings from Breakthrough’s report.
  • 📊 Rapid Warming: Global temperatures have already reached 1.5 degrees Celsius, surpassing previous projections and raising alarms among scientists.
  • ⚠️ Tipping Points: Several key climate system tipping points have been crossed, signaling irreversible changes in critical environments such as coral reefs and polar ice.
  • 🔥 Increasing Extremes: Climate extremes are more frequent and severe, affecting weather patterns and causing devastating impacts worldwide.
  • 🏭 Inadequate Decarbonization: Current government policies are insufficient in reducing greenhouse gas emissions, with a lack of commitment to genuine reductions.
  • 🚨 Cascading Risks: Climate risks are interconnected and systemic, leading to potential crises in food security, water supply, and geopolitical stability.
  • 🎤 Public Engagement: The discussion emphasizes the importance of public dialogue and grassroots movements to drive climate action and policy change.
