Our second IPCC overview post is now live!This time we turn from the physical science of the climate system (WG I) to the real-world impacts on people, ecosystems, and economies — the work of Working Group II (WG II).
WG II examines how climate change affects lives and livelihoods, and how societies can adapt to reduce harm and build resilience. It links scientific data to lived experience — identifying who is most vulnerable, where risks are rising fastest, and what actions can help.
🗺️ The post includes three key maps from the IPCC’s Sixth Assessment Report (AR6):
- Observed Human Vulnerability — showing where deaths and damages from floods, storms, droughts, and heat are highest.
- Global Drought Risk — highlighting regions where water stress and exposure make communities most at risk.
- Mountain Water Resources — revealing how melting glaciers and snowpack affect livelihoods and economies downstream.
Each map connects physical hazards to human vulnerability — the heart of WG II’s mission.
💬 Look at the first map (Observed Human Vulnerability).
- Which regions surprise you most?
- Do you recognise patterns that link to social or economic inequality?
- What types of adaptation could make the biggest difference where you live?
Share your thoughts in the comments — and stay tuned for the next post on Working Group III, where we’ll explore how the IPCC assesses mitigation and solutions to reduce future risks.
