No Time for Half Measures: A Security Perspective on the New IPCC Report on Mitigation

By Sofie Bliemel and Brigitte Hugh

The Intergovernmental Panel on Climate Change (IPCC) Working Group III (WGIII) on Mitigation released its contribution to the Sixth Assessment Cycle (AR6) on April 4 after the longest approval plenary in the IPCC’s history. The top-line takeaway from the third and final report of AR6 is that global emissions must peak by 2025 if the world is to avoid global warming over 2°C this century. “It’s now or never, if we want to limit global warming to 1.5 degrees Celsius,” said IPCC WGIII co-chair Jim Skea, calling for immediate and deep emission reductions to avoid intensifying climate risks.
