When a major climate event goes almost unnoticed: the elusive 8.2 ka signal in southern France stalagmites

  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]

Exploring Earth’s interior with analogue models: The case of slow earthquakes

April 2, 2026
Analogue experimental setup of spherical hydrogel suspension.

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]

The sassy scientist: we regret to inform you

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]

CLOUDLAB: Cloud research in a natural laboratory

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]

Art, science, and seismic memory

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]

Geodesists on Tour: Circumnavigating Greenland by Helicopter

  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]

An isolated fjord at the edge of the Southern Patagonia Icefield. A small cluster of tents pitched beside Bernal Glacier. Fourteen days without roads, cell reception, or routine – only creaking ice fronts, restless wind, the constant murmur of meltwater, unrelenting rain, and a team of fellow adventurers as companions. The Patagonia Icefield Research Program (PIRP) is an immersive classroom where ...[Read More]

How atmospheric circulation patterns high above the Southern Ocean influence the deepest layers of the global ocean

How atmospheric circulation patterns high above the Southern Ocean influence the deepest layers of the global ocean

The ocean surrounding Antarctica plays a crucial role in the climate system. Along parts of the Antarctic coast, very cold and salty water becomes dense enough to sink all the way to the ocean floor. This process forms Antarctic Bottom Water: the deepest water mass in the global ocean, representing about 40% of its total volume. As this dense water sinks into the abyss, it helps trap heat and carb ...[Read More]

Communicating and Managing Residual Risk with Perfect Storms and Other Counterfactual Stories

The aim of risk management is to prepare society in order to limit loss and damage when an extreme event occurs and to restore the functioning of society afterwards . While current risk management practices are helpful in many regards, they fall short when it comes to unprecedented events. An analysis of event pairs and recent disasters show that societies often fail to cope with events that are l ...[Read More]
