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. 


EVENT SUMMARY: IPCC Authors Underscore Importance of Governance, Adaptation to Reduce Climate Vulnerability

By Brigitte Hugh 

Our responses to climate challenges, or lack thereof, increasingly play a role in the severity of impacts on human systems. That’s part of “what makes climate risks so challenging to manage,” said Dr. Katharine Mach, a lead author on the Working Group II report of the Intergovernmental Panel on Climate Change (IPCC) Sixth Assessment Cycle (AR6) at an event hosted by the Center for Climate and Security (CCS) on March 8, 2022. 

The event, “Decoding the IPCC report on Climate Impacts: Implications for Security and Adaptation,” featured Dr. Mach, fellow lead author, Dr. Halvard Buhaug, and Dr. Rod Schoonover, Head of the Ecological Security Program at the Council on Strategic Risks.


New IPCC Report Calls for Adapting Today to Ensure Tomorrow’s Climate Security

By Brigitte Hugh and Sofie Bliemel 

“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. 


Event: Decoding the New IPCC report on Climate Impacts: Implications for Security and Adaptation

By Brigitte Hugh

Join the Center for Climate and Security on March 8, 2022 from 12-1 p.m. EST for “Decoding the New IPCC report on Climate Impacts: Implications for Security and Adaptation,” a panel discussion featuring report authors and security experts. RSVP to attend the event here.

Background: On February 28, 2022, the Intergovernmental Panel on Climate Change (IPCC) will release the second report in the Sixth Assessment (AR6) cycle. The Working Group II (WGII) Report, Impact, Adaptation, and Vulnerabilities will lay out “the latest evidence on how past and future changes to Earth’s climate system impact life on our planet,” as well as the system capacities and limits for equitable and sustainable adaptation.
