Thanks to the enthusiastic efforts of our members and volunteers, EGU26 was another record breaking year with an amazing 22,497 people participating in the General Assembly, both in Vienna and online!
New research shows extreme heat and humidity are already pushing Hajj pilgrims beyond survivability limits, with the greatest danger during Arafat and future pilgrimages expected to become more hazardous.
Solar storms can quietly disrupt satellites, power grids, and communication systems across the globe. After a 2022 geomagnetic event knocked out dozens of Starlink satellites, the risks are no longer hypothetical. At EGU26, scientists unveil Swarm-AWARE, a new ESA project using satellite data and machine learning to distinguish space weather signals from natural hazards, paving the way for smarter forecasting and more resilient infrastructure.
For 350 million years, ammonites were the resilient masterpieces of the ancient seas. They survived the Great Dying of the Permian-Triassic, an event that wiped out 96% of marine life, only to vanish during the end-Cretaceous extinction that claimed the dinosaurs. Meanwhile, their less-diverse cousins, the nautiloids, sailed through the catastrophe and still inhabit our oceans today.
Why did the invincible ammonites fail while the nautiloids endured?
In one of the most water-stressed regions on Earth, Saudi Arabia is facing a critical paradox: its ancient aquifers are being depleted faster than they can recharge, yet a massive strategic asset is being flushed away. Every year, the country produces 1.6 billion cubic meters of treated wastewater that remains underutilized, an amount equivalent to roughly 60% of Saudi Arabia’s annual urban drinking water demand.
For more than a decade, I have spent a large part of my time not only doing research in planetary science, but also visiting schools, science festivals, public events, and talking to children, teachers, and everyone interested in geosciences. During these outreach activities I repeatedly encountered the same problem. People were genuinely curious about volcanoes, earthquakes, plate tectonics, or the interior of our planet, but when teachers asked me where they could find simple experiments to demonstrate these processes in …

Hello blog readers! It’s Jean-Baptiste and Alexis. With EGU26 now behind us and summer approaching fast, we wanted to announce the start of the 9th blogging season for the Geodynamics division and introduce the team for the 2026–2027 year. We both have the privilege and the daunting challenge of succeeding Constanza and Michael as Editors-in-Chief of the Geodynamics Blog. Over the past three years, they have done a remarkable job with tremendous talent and kindness. Luckily for all of us, …
