In mountainous areas, earthquakes can sometimes be amplified by the shape of the landscape. Research by the University of Twente shows that further from the epicentre, the shape of the terrain's topography increases the risk of landslides. Closer to the epicentre, it is mainly the strength of the earthquake itself.

A new study published in Nature unveils a surprising discovery: a substantial amount of meltwater is temporarily stored within the Greenland Ice Sheet during summer months. For the first time, an international group of researchers was able to quantify meltwater with positioning data. The finding challenges current models of how ice sheets contribute to global sea level rise.

For over a year and a half, researchers from TU Delft and the Cambridge University Centre for Climate Repair have worked together on groundbreaking techniques to increase the reflectivity of clouds in the fight against global warming. During a two-day meeting, the teams are discussing their progress.

Stuart Pearson, coastal engineer at TU Delft, receives a NWO Veni grant to investigate sediment pathways. He will specifically focus on tracking individual sand grains. Revealing the interconnected network of sediment pathways that shape our coast will help us to better manage the sediment that builds ecosystems and protects us against flooding.

On July 5, 2024, five researchers from Radboud University will travel to the far north to research climate change on Svalbard. For a week, the scientists, led by earth scientist Wytze Lenstra, will take samples of the sea floor and water column in one of the fjords. The archipelago is seen as a "natural laboratory" for studying the impact of climate change in the future: these Arctic regions are warming up to about four times faster than the global average.

The ocean can store carbon and act as a carbon sink, and it can be a carbon source. The difference in 'age' of the organic carbon already present in the ocean and the carbon that is supplied determines whether the ocean acts as a carbon sink or source. Researchers from Nanjing universities and Utrecht University created the first sink or source world map that can be used when deciding where to invest in organic carbon storage in the ocean.

Climate change can accelerate due to feedback mechanisms: complex phenomena caused by climate change that in turn can further drive climate change. An example is the extra CO2 emissions from thawing permafrost. Research into the influence of feedback mechanisms in the long term has been ongoing, and modern climate change research is obviously happening as well, but the connection between the two has so far been underemphasized.

A groundbreaking study by an international team of researchers has revealed seaweed forests to be significant contributors to oceanic carbon storage. Their research estimates that the world's seaweed forests transport 56 million tonnes of carbon (between 10 to 170 million tonnes) to deep ocean sinks each year.

The period that liquid water was present on the surface of Mars may have been shorter than previously thought. Channel landforms called gullies, previously thought to be formed exclusively by liquid water, can also be formed by the action of evaporating CO2 ice. That is the conclusion of a new study by Lonneke Roelofs, a planetary researcher at Utrecht University.

Researchers from Utrecht University have successfully simulated the collapse of the large-scale ocean circulation in the Atlantic Ocean using a complex climate model, revealing severe global climate repercussions with Europe bearing the brunt. They published their findings in the scientific journal Science Advances today.

Beyond 2°C of global warming, the risk of one climate tipping element triggering other tipping elements in the Earth's climate system strongly increases. Furthermore, most of these interactions are destabilising. This is the result of a new study by an international team of scientists, led by Anna von der Heydt from Utrecht University and Nico Wunderling from the Potsdam Institute for Climate Impact Research.

A team of researchers from TU Delft has succeeded in long-term mapping of beach topography to within a few centimetres. The unique dataset provides insights into coastal changes for every hour, for three years. This data is important for dune maintenance and to keep the hinterland well protected. The methodology is also being used to monitor other coastlines and even glaciers.
