From lithium cells to sand, water, and even gravity, there’s more than one way to store energy. Each battery type has its own strengths, weaknesses, and environmental impact. This lesson breaks down how the main technologies work, what they’re made from, and where they fit in the energy puzzle. 👉 Find it here.

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 - 💬 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. 👉 Find the post in the Classroom in "Sources that Matter" - Or Click Here Coming soon: WG II: Impacts, Adaptation & Vulnerability.

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): 1. Observed Human Vulnerability — showing where deaths and damages from floods, storms, droughts, and heat are highest. 2. Global Drought Risk — highlighting regions where water stress and exposure make communities most at risk. 3. Mountain Water Resources — revealing how melting glaciers and snowpack affect livelihoods and economies downstream. 4. 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. 👉 Read the full article here

Some industries can afford to ignore climate change — others simply can’t. This lesson explores the sectors that deal in reality, not rhetoric: insurers, banks, engineers, farmers, scientists, doctors, and even the military. Each of them is already adapting — raising flood defences, rewriting risk maps, reinforcing ports, changing crops, or redesigning hospitals — because they have no choice. Their decisions quietly reveal where the world is heading. Find it here. 🧭 Your challenge: Find one example near you (or in a country you follow) where a company, profession, or government branch is getting real about climate change. - What’s changing? - Why now? - Which “truth-telling sector” does it belong to? - 📸 Optional: post a link, quote, or image showing the shift. Together, let’s build a global picture of where action is already underway — not promises, but proof.
