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.
“The future depends on us, not the climate,” said Dr. Helen Adams from King’s College London, a lead author of the Working Group II (WGII) contribution to the Intergovernmental Panel on Climate Change’s (IPCC) Sixth Assessment Report (AR6), published on February 28, 2022. In this article we discuss its implications for the climate-security nexus.
The newest publication focuses on climate change impacts, adaptation, and vulnerabilities, building on the Working Group I report, released in August 2021, which explored the physical science of climate change. At the end of March 2022, the Working Group III installment of AR6, on mitigation, will be released. The report paints a grim picture of already irreversible climate threats, underscoring the importance of climate resilient development to reduce risks. “Taking action now” will determine societies’ vulnerability to climate hazards and resulting disasters and conflict.
