Rising sea levels spell danger for shorebirds such as oystercatcher
Research by James Cook University in Australia involving Radboud scientists shows that rising sea levels will drastically reduce the number of shorebirds in Europe. The number of oystercatchers on three Waddeneilanden will decline an additional 56 to 79 percent over the next 100 years due to sea level rise.

Midnight sun on Svalbard: expedition to phytoplankton
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.

Fewer measurements required to determine level of pharmaceutical residues in wastewater due to new model
It is becoming increasingly obvious that pharmaceutical residues in wastewater are damaging to the environment, making it imperative that wastewater is tested for such residues. However, wastewater measurements are expensive and time-consuming. A new model developed by Radboud University-affiliated environmental scientist Caterina Zillien can be used to determine the amount of pharmaceutical residues in wastewater - and their exact origin - every bit as precisely as actual measurements.

Age of organic carbon important factor in ocean carbon storage
Age of organic carbon important factor in ocean carbon storage
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.

Sustainable plastics are not a solution, researchers warn
With hundreds of millions of tonnes of plastic produced and used on a yearly basis, it's no surprise that people are looking for alternatives. Yet so-called 'sustainable plastics' are not a silver bullet, warn researchers Sara Gonella and Vincent de Gooyert from Radboud University. When looking at the full impact of these plastics, they are often not nearly as sustainable as they pretend to be, they argue.

Thawing permafrost: not a ticking time bomb, but cause for urgent concern
Thawing permafrost: not a ticking time bomb, but cause for urgent concern
The thaw of permafrost is not a global climate 'tipping point'. That is the conclusion of an international group of scientists, including earth scientist Moritz Langer. Rather, permafrost soils are thawing along with global warming. "There is no safe margin within which the Earth can warm up, as a tipping point suggests." Permafrost soils store large amounts of organic carbon in the form of dead plant material.

30 million euros for research into climate change feedbacks
30 million euros for research into climate change feedbacks
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.

Pre-collapse monitoring of Kakhovka Dam in Ukraine
Pre-collapse monitoring of Kakhovka Dam in Ukraine
New findings from a spaceborne monitoring team of University of Houston, TU Delft and DLR indicates the collapse of the Kakhovka Dam in Ukraine may have been already ongoing before the war with Russia, with deformations in the dam pre-dating the actual collapse. The results were published in the journal Nature Communications Earth and Environment this month.

Seaweed forests are an overlooked component of oceanic carbon storage
Seaweed forests are an overlooked component of oceanic carbon storage
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.

When simply reusing solar panels beats recycling
When simply reusing solar panels beats recycling
Core changemakers wants to give used solar panels a second life. As the world steadily progresses towards a more sustainable future, recycling solar panels becomes increasingly relevant. However, in some cases, simply reusing old solar panels is better. CORE CHANGEMAKERS, once a student team at Eindhoven University of Technology (TU/e) and now evolving into a startup, is exploring the possibility of using old solar panels.

Residual waste from mushroom cultivation removes pollutants from water
Water can be purified using mushroom substrate: the mixture of fungal filaments and horse manure that remains after harvesting mushrooms. The substrate effectively decreases concentrations of pesticides and drugs in contaminated water. Utrecht researchers Brigit van Brenk , Han Wösten , and colleagues demonstrate this in a paper in the scientific journal Applied Microbiology and Biotechnology.

Renewed efforts needed to reach international biodiversity goals
Renewed efforts are needed to reach international biodiversity goals, according to an international study involving scientists from Radboud University, published in Science. The study shows that climate change could be the main driver of biodiversity decline by the mid-21st century. The analysis was led by the German Center for Integrated Biodiversity Research (iDiv) and Martin Luther University Halle-Wittenberg (MLU) and is the largest modeling study of its kind to date.

Good news for deltas: increase in sediment since 2000
When you build a dam on a river, less sediment can get to the sea, which makes deltas more susceptible to floods. This idea's been believed for a long time, however new research from Utrecht University shows that the amount of sediment in deltas has actually increased since 2000. This is good news for preserving deltas - like the Netherlands - from sea level rise.

Small rivers tell the story of thawing permafrost
What effect does climate change have on Arctic permafrost? Earth scientist Niek Speetjens conducted research in Canada and discovered that the small river systems provide a lot of insight into the thaw of permafrost. Permafrost, permanently frozen soil, is thawing due to climate change. This has consequences for water and carbon transport through river systems that flow into the sea from areas with permafrost.
