Every year on 21 June, the global scientific community celebrates World Hydrology Day to highlight the importance of water sciences play in sustainable resource management and natural hazard mitigation. Historically, human efforts to protect and manage freshwater have suffered from a blind spot. While we can easily measure a river’s flow at a specific gauging station, predicting how an untou ...[Read More]

Footprints reveal climate’s mark on mudflats

Tidal flats, the muddy reaches of estuaries unveiled at low tide, support rich ecosystems and fisheries worldwide. But these habitats are under threat from climate change, as sea level rise overwhelms the landscape and heavy rainfall scours away the sediment – impacts that scientists are only just beginning to explore. In an effort to understand how shellfisheries are affected by climate change, a ...[Read More]

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 a geoscientific lens. On ...[Read More]
