🌊 Floods cause 44% of disasters, hit 1.6B people & cost $650B.
They’re systemic:
🔹 Climate shifts 🌧️❄️🌊
🔹 Urbanisation 🏙️
🔹 Deforestation 🌲
🔹 Marginalisation ⚠️
Solutions: governance, tech, social knowledge & nature-based solutions: ow.ly/xCsi50ZYtut

Schnelles Auftauen: Wie schnell Eis in Permafrostgebieten schmelzen kann, wurde bei Feldarbeiten im Blockgletscher Muragl im Jahr 2024 deutlich, wo aus einem Bohrloch Wasser in einer hohen Fontäne entwich und offensichtlich unter hohem Druck stand. extremes.wsl.ch/de/extremeth…
Real change often happens through personal conversations. But creating curiosity, making impacts tangible can be an important first step.

This autumn, leave the leaves to help biodiversity in urban areas 🍂
It's a protective habitat layer insulating the soil, providing safe overwintering cover for animals, and feeding local food webs
We all can help protecting habitats – starting in our gardens

Extreme weather is intensifying, and its impacts fall hardest on those with the least protection.
☂️ Reducing climate risks at scale demands both stronger adaptation and faster emission reductions.

Europe's rivers are warning us: By 2030, global demand for freshwater is expected to exceed supply by 40%.“If you have a lack of water, you will have a lack of drinking water, a lack of food, a lack of energy, and a lack of biodiversity,” Zappa concludes.

🌡️ Your city is getting hotter. What would you invest in first?
🏠 Cool roofs?
🌳 More urban greening?
🚨 A heat response plan?
The answer may depend on where you live.

Klimaschutz ist entscheidend gegen das steigende Waldbrandrisiko, nicht nur Anpassung, erklärt PIK-Forscher Maik Billing im DLF. Heißes, trockenes und windiges Feuerwetter sei der wichtigste Treiber des zunehmenden Brandrisikos.

Wildfires are burning across Europe right now. But how do satellites actually track them? 🔥🛰️
In her latest seminar, Dr Lucrecia Pettinari – who is the Project Manager of the ESA Climate Change Initiative Fire project – explains how remote sensing maps fuel types, tracks vegetation dryness, detects active fires in near real-time, and maps burn scars after the fact.
The data is powerful. But cloud cover, land use changes, and rapid tropical regrowth all make consistent monitoring challenging.

Breaking News!
Code: y-Axis alert!
The latest global preliminary sea-surface temperature for August 23rd blew away the previous record set just yesterday. I had to raise the y-axis to accomodate the new record.
Will I have to extend the y-axis again tomorrow? Stay tuned.

🛑 There’s no such thing as a natural disaster — disasters occur when risks are ignored.
⚡ Hazard – dangerous events
🏙️ Exposure – people/assets at risk
🧩 Vulnerability – conditions increasing harm
