The first of our three new IPCC overview posts is live! This one introduces Working Group I (WG I) — the team of scientists who build the physical foundation for everything else the IPCC does.
WG I studies the Earth’s climate system itself — how energy flows through the atmosphere, oceans, ice, and land, and how human activities are changing it. To make sense of global data, they divide the world into 61 “Reference Regions”, each with its own patterns of temperature, rainfall, and extremes. These regions appear throughout the IPCC’s Interactive Atlas and underpin every map of past and projected climate change.
🗺️ The post includes:
- A full-colour WG I Reference Regions map
- A short guide to what the map is for and how it’s used
- Links to explore the Interactive Atlas yourself
đź’¬ Activity prompt: After reading the post, scroll through the Interactive Atlas and choose a region you know or live in.
- What trends do you notice for temperature, rainfall, or extremes?
- Does the data match what you’ve experienced? Share your reflections in the comments.
Coming soon: WG II: Impacts, Adaptation & Vulnerability.
