Ralph Alger Bagnold (3 April 1896 – 28 May 1990) was a British engineer, geomorphologist, desert explorer, and soldier. His work fundamentally changed our understanding of sediment transport. His pioneering studies of wind-blown sand and desert dunes established a quantitative, physics-based approach to aeolian geomorphology. Bagnold’s scientific career was closely connected with his fascination with …[Read More]
Floods in one region. Droughts in another. Wildfires intensifying across already dry landscapes, while elsewhere intense rainfall triggers landslides and infrastructure disruption. At first glance, these hazard events may seem entirely unrelated. After all, what could a flood on one side of the world possibly have to do with a drought on the other? Yet …[Read More]
In 2025, Climate of the Past celebrated its 20th anniversary. Over the past two decades, the journal has become a leading open-access publication in paleoclimatology. It provides a platform for research into how the Earth’s climate has changed over time, and how these changes can inform our understanding of the current climate system. To celebrate …[Read More]
Climate models help us understand how the climate system works, project future climate change, and provide evidence that supports international assessments such as exposed on the IPCC. At this point, there is a fundamental question that is rarely discussed and solved: Can we access and reproduce the climate models used throughout the history of the …[Read More]
Ice shelves, the floating margins of the Antarctic ice sheet, play an important role in the estimation of future sea-level rise. By their presence, they act as a brake on the flow from the grounded ice sheet to the ocean and therefore modulate how much of this ice is added to the ocean. As the …[Read More]
The looming El Niño is likely to hit hard this year, bringing bracing moments to the already warming world. Extreme weather events are no longer just anomalies; they have become far too common in this new reality. It’s clear that our environment is under unprecedented stress. Experts warn of the costs of inaction: between 1995 …[Read More]
Travel across the globe and you will see landscapes change along the way. But what if the same were true inside Earth? What if the landscapes we see on the surface also exist deep within? In this week’s Geodynamics 101 post, Ankit Barik, Assistant Research Scientist at Johns Hopkins University, explores the hidden topography deep inside …[Read More]
Extreme rainfall and strong winds can each cause major disruption. When they occur together—or within only a few days of each other—their combined impacts can be even more severe. Heavy rainfall may saturate soils and increase flood risk, while strong winds can damage infrastructure, disrupt transport and bring down trees or power lines. Forecasting these …[Read More]
A note from the Natural Hazards Division editorial team We would like to open this blog post with our sincere condolences in response to the devastating multi-hazard flash flood that occurred in Nepal and Tibet in late August. In the face of such suffering, messages like this risk sounding hollow. Still, we, as the Natural …[Read More]
When I joined the European Geosciences Union in 2024 as a media professional, my primary mandate felt straightforward: democratising scientific understanding and building durable, trustworthy bridges that connect scientists, researchers, journalists, and public communicators. Now, in my third year at EGU, I find myself looking out over our scientific community with a mixture of reverence …[Read More]
