Practical Use of Natural Hazard Monitoring Systems during Escalating Risk Scenarios

Mountain hazard regimes are fundamentally shifting. There is consensus not just among concerned scientists, but practitioners of risk management, that mountain hazard regimes are affected by warmer temperatures and intensifying precipitation events. The effects of these changes are further amplified by increasing population density in known hazard zones; with more infrastructure and human settlements in …[Read More]

Drought in Europe

Drought in Europe

Many of us are experiencing it right now: Europe is suffering from a long lasting large scale drought (Fig. 1), with record heat and low-flow levels that probably nobody of us has seen before; and current forecasts do not announce any relieve for the coming weeks. The pictures of record low levels in the river …[Read More]

Under the Mediterranean sun: The thousand year tale of changing skies

Under the Mediterranean sun: The thousand year tale of changing skies

When you picture the western Mediterranean, you likely imagine sun-drenched beaches, terracotta roofs, and bright blue skies. But has it always been this sunny? A groundbreaking study published in the journal Research provides a definitive answer: it has not. By pulling back the curtain – or rather, the cloud cover – on a thousand years of …[Read More]

Has groundwater finally gone mainstream?

Has groundwater finally gone mainstream?

Groundwater has always had an image problem. Throughout my career, I have lost count of how many times we have described groundwater as an “invisible resource” or similar. It is almost a cliché in hydrogeology. We use the phrase because it captures something really fundamental: groundwater is hidden physically, but it has also been hidden …[Read More]

Mobilidiocy

Mobilidiocy

Guess who’s back? Back again! Sassy’s back, tell your colleagues! This week I am going to shoot the elephant in the room by answering Will’s question “Is Mobility a plus or a must for a research career?” Now I know I have already answered a similar question some time ago, but a changing world requires …[Read More]

A geoscience reality check on World Biofuels Day

A geoscience reality check on World Biofuels Day

On a humid morning in Augsburg, Germany, on August 10, 1893, a ten-foot iron cylinder roared to life for the first time. The engine belonged to Sir Rudolf Diesel, and running through its veins was not the petroleum distillate we associate with his name today, but in fact, peanut oil! Diesel’s early experiment proved something …[Read More]

When the atmosphere moves the sea: Meteotsunami waves

When the atmosphere moves the sea: Meteotsunami waves

Meteotsunamis or meteorological tsunamis are globally occurring progressive shallow water waves with a period of between 2 to 120 minutes which results from an air-sea interaction. They tend to be initiated by sudden pressure changes and wind stress from moving atmospheric systems with sources ranging from convective clouds, cyclones, squalls, thunderstorms, atmospheric gravity waves and …[Read More]
