Climate change is having a profound impact on the planet. According to several reports, 2023 was the warmest year on record, with the global average temperature over the 12-month period from February 2023 to January 2024 exceeding the 1.5 °C threshold above pre-industrial levels. Climate change acts as a risk multiplier, as its impacts transcend national borders and amplify existing threats and cr ...[Read More]
A robust estimation of probabilities of extreme floods is the Holy Grail in flood hydrology in view of limited available observations, variability of climate, and complexity of flood generation processes in catchments. Flood frequency hydrology, spearheaded in the past decades by Ralf Merz and Günter Blöschl, offers a powerful toolbox to enhance the reliability of flood probability estimates by co ...[Read More]
Around 8,200 years ago, the climate of the Northern Hemisphere experienced an abrupt disturbance. In Greenland ice cores, the signal is unmistakable: a rapid drop in temperatures, followed by a gradual return to previous conditions. This episode, which lasted about 150 years, is known as the 8.2 ka event (“ka” meaning thousand years before 1950). It is often described as the most prominent ...[Read More]
Have you ever heard of “analogue modelling”? In solid Earth science, directly observing the Earth’s interior is challenging, and the analogue modelling approach often overcomes this limitation by using alternative systems analogous to natural phenomena. By identifying fundamental mechanisms in these tractable systems, we can apply physical scaling laws to understand processes dee ...[Read More]

With the winds of change brought by a new season, I’m back to help my readers to get out from dispair. This time a reader ask: Dear Sassy scientist, How do I deal with rejection during a job hunt? Dear Sarah, I hear you writing from the edge of despair. Let’s be honest: you’ve chosen the scenic route to career purgatory. Nevermind watching your lifelong friends enjoying their permanent contr ...[Read More]
Each month we feature specific Divisions of EGU and during the monthly GeoRoundup we put the journals that publish science from those Divisions at the top of the Highlights section. For March, we are not featuring any particular divisions, but an ensemble of all the highlights of this month instead. Atmospheric Chemistry and Physics Emerging low-cloud feedback and adjustment in global satellite ob ...[Read More]
It’s murky grey, windy, and freezing when we head out into the countryside of the Swiss pre-Alps. We are looking for low hanging clouds to serve as our natural laboratory. Wintertime low stratus clouds can cover Switzerland for days. This type of cloud is stable with temperatures below 0 ºC and it contains plenty of liquid cloud droplets, but no ice crystals. These are the perfect background condi ...[Read More]
The contribution from Sergio León-Ríos, Associate Researcher at the Advanced Mining Technology Center (AMTC) at the University of Chile, where he does seismology research. Introduction Earthquakes and tsunamis are not only purely scientific geophysical phenomena. They are also deeply embedded in social memory, cultural narratives, and everyday life – especially in countries like Chile, where ...[Read More]
Greenland, the world’s largest island, has one of the most challenging environments for geodetic measurements. Maintaining GNSS (Global Navigation Satellite Systems) stations here isn’t just about precision – it’s about ensuring data continuity in an area that’s constantly moving. This is the behind-the-scenes story of a 15,000 km journey around Greenland: five weeks of helicopter-bas ...[Read More]
