Grosser Aletsch Glacier Rapid Snow Loss June 2026

In June of 2025 heat waves combined with limited winter snowpack set the stage for significant glacier loss, 3% of the volume of Swiss Glacier. This followed on the exceptional losses in 2022 and 2023. This same story in playing out through Ju...

The 2026 Venezuela earthquakes

Volcano Cafe | 26 June, 2026
Some fault systems in the world are well known for their destructive potential. Examples are Turkey's North Anatolian fault and California's San Andreas. In both cases, large events in the not-too-distant future are widely predicted. In Turkey, t...

The Oligocene dolphin Xenorophus, part 3: new insights into the growth, variation, functional anatomy, asymmetry, and phylogeny of early odontocetes

This is intended to be the third and final installment in this series, and I'll probably forget something in here - but here goes! The Xenorophus monograph was a monumental task to write and publish, and this "cliff notes" version will probably fail to cover everything. There's a LOT of meat in there, so who knows how many additional posts I'll have to make. To see part 1, click here, and for part 2, click here.

GeoTalk: meet Delphine Urbah, space anthropologist!

EGU Geolog | 26 June, 2026
Of course, a spacecraft is not a prison or a hospital, but the comparison, maybe closer to a submarine or an Antarctic base; also total institutions, helps us understand why rights and responsibilities cannot be left vague. A legal and ethical framework does not mean controlling every personal gesture or belief. Rather, it helps clarify how freedom of conscience, cultural practices, privacy, non-discrimination, and mission constraints can coexist.

From Quasars to Coordinates: How VLBI Measures Earth’s Shape and Motion

EGU Geodesy Division | 26 June, 2026
Imagine determining the position of a point on Earth with millimeter precision using radio signals from celestial objects billions of light-years away. This may sound like science fiction, but it is exactly what Very Long Baseline Interferometry (VLBI) allows scientists to do.

Melting ice shelves in ocean models: an idealised model intercomparison project

The Antarctic ice sheet is losing mass through the ice shelves fringing the continent, contributing to global mean sea level rise. The warm ocean brings heat towards the floating ice shelves and into the ocean beneath them, called ice shelf cavities. The ocean heat melts the ice from beneath, which then allows the ice sheet to slide forward into the ocean and raise sea levels. However, the processes that happen at and below ice shelves are complex and involve both small and large spatial and temporal scales. They are also hard to observe due to their remote nature (if you are curious about observing the interface between ice and ocean, check out this post). Therefore, it is important that we invest in developing robust and reliable models of ice shelf processes to accurately predict their influence on future climate and sea level.

The CCS parallel universe

GEOExPro | 26 June, 2026
Sometimes, I cannot prevent the feeling that the CO2 storage business is not so much about putting CO2 in the ground, but rather to keep an en­tire academic research community, a conference industry, and a contingent of geoscientists in a job. When it comes to academia, I see professors winning grants to do research that...

The day I realised I had nothing to offer teachers: The story behind Almanac of Geoscience experiments

EGU Geolog | 25 June, 2026
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 the classroom, I often realized that I did not have much practical material to recommend.
