Chasing Auroras 41 Millennia Ago with Agnit Mukhopadhyay and Sanja Panovska

Guram July 18, 2025

Approximately 41,000 years ago, during the Laschamps geomagnetic excursion, Earth’s magnetic field experienced a significant disturbance. The strength of the magnetic field decreased to only 10% of what it is today, the magnetic poles shifted considerably from the geographic poles, and the magnetosphere—the protective layer surrounding our planet—became smaller and distorted in previously unvisualized ways. …[Read More]

🌱 Nurturing the Next Generation of Soil Scientists: Meet the SSS EGU Early Career Scientists Team

Beatrice Giannetta, Antonio Girona-García and Christhel Andrade July 17, 2025

Soil is more than just dirt beneath our feet, it’s a living, breathing system that sustains ecosystems, regulates climate, and supports agriculture. At the heart of advancing our understanding of these vital systems is a dynamic group of early career researchers working within the Soil System Sciences (SSS) Division of the European Geosciences Union (EGU). …[Read More]

Sixty years under the mountain: A geoscientific odyssey through the Mont Blanc tunnel

Asmae Ourkiya July 16, 2025

On July 16, 1965, the Mont Blanc Tunnel, 11.611 km of tunnel piercing the heart of the Alps, opened to traffic, marking a triumph of engineering, geology, and international cooperation. Sixty years later, this civilian artery connecting Chamonix (France) and Courmayeur (Italy) stands not just as a testament to human inventiveness but as an ongoing marvel if viewed through …[Read More]

Unraveling volcanic patterns between adjacent rift zones

Valentina Armeni and edited by Lorenzo Mantiloni July 16, 2025

Continental rifts are a prime example of how the forces at work beneath our feet are constantly shaping our world, and often host volcanic activity. The patterns and distribution of volcanism in rift settings, however, is far from intuitive. The picture gets even more complicated if we look between the segments that often make up …[Read More]

Surviving the Ranking Madness: A Geoscientist’s Guide to Keeping Your Academic Soul Intact

Guest author July 15, 2025

The Academic Identity Crisis Ever googled yourself to check if your h-index went up? Compared your publication statistics to a peer? Published in a paywall journal while cursing the system? – Same. Welcome to the slightly neurotic world of academic evaluation—where current incentives often pull us away from the values we hold as scientists: curiosity, …[Read More]

How is earthquake-driven sea-level rise changing our coasts?

Navakanesh M Batmanathan July 14, 2025

Coastal regions have always been at risk from natural hazards, but now, there’s an added layer of complexity. Earthquakes, which cause the land to move up or down, can significantly affect sea levels, especially in regions already experiencing the effects of climate change. Earthquakes can alter coastlines in ways that we’re still trying to understand, …[Read More]

The Untapped Potential of Citizen Science Onboard Expedition Cruise Vessels

Holly Stainton July 11, 2025

Scientific work can be done not only by professional scientists but also by the general public, often in collaboration with scientific institutions. At HX Expeditions, citizens have the opportunity to contribute to scientific projects on expedition cruises. Join us as we hear from Holly Stainton, the Science & Education Coordinator at MS Roald Amundsen and …[Read More]

The false narrative of over-population: why Malthus had it wrong when it comes to global resources

Asmae Ourkiya July 11, 2025

Just like me, you may have, at some point in your life, come across Malthusian rhetoric: There are too many mouths to feed and not enough resources for a growing population. But what if the problem isn’t people, but an appetite for profit-driven extraction? In this blog, I peel back the myth of overpopulation and …[Read More]

The Proglacial Puzzle: Sampling of Glacier-fed Lakes in Greenland

Joost van Genuchten July 11, 2025

Would you like to follow the endeavours of a small team working in the ice-marginal terrain in South-West Greenland? They set out to investigate proglacial lakes using sediment coring, water sampling and gas collections (figure 1), aiming to better understand methane dynamics, proglacial terrain development and the environmental drivers behind methane production in glacially influenced lake …[Read More]

AI-generated Images: the fragility of visual evidence in geosciences

Davide Faranda and Tommaso Alberti July 9, 2025

Recently, an increased number of visually striking “scientific” images have been found online: snapshots of turbulent flows with dreamlike structure, eerily symmetric cloud patterns, and what appeared to be global temperature fields annotated with plausible colormaps and scientific-looking labels. Many of these posts quickly go viral on social media. And yet, in many cases, the …[Read More]
