The threat of microplastics to swiss wildlife and ecosystems

Each year, approximately 14,000 tons of plastic find their way into Swiss soils and waters, including microplastics, which are minuscule particles ranging from micro to millimeter size. These microplastics originate from various sources, such as cosmetics and synthetic fiber clothing. Additionally, they are generated through the wear and tear or breakdown of larger plastic items, … Read more

Campi Flegrei supervolcano becoming weaker, more prone to rupture

Researchers at UCL (University College London) and Italy’s National Research Institute for Geophysics and Volcanology (INGV) have conducted a new study indicating that the Campi Flegrei volcano in southern Italy has become more unstable and susceptible to eruption. The volcano has exhibited restlessness for over 70 years, experiencing periods of heightened activity in the 1950s, … Read more

Mercury emissions from power plants decreased by 90% after MATS implementation

The remarkable success of the federal government’s prominent environmental laws is often overlooked in partisan political debates concerning regulations impacting the energy sector. One such example is the U.S. Environmental Protection Agency’s Mercury and Air Toxics Standards (MATS), which aimed to reduce hazardous air pollutant (HAP) emissions from fossil fuel-fired power plants. According to a … Read more

New study shows how to account for snowpack loading in groundwater assessments

The Sierra Nevada Mountains accumulate massive amounts of snow, which can cause parts of the Central Valley, located to the west, to sink. This phenomenon has complicated groundwater assessments because the sinking is often mistaken as a depletion of aquifers. However, a recent study conducted by Stanford University has provided a solution to this problem, … Read more

Deep earth forces dominate mountain building, study finds

A recent study conducted by Colorado State University reveals that the explanations for how and why mountains are formed may be more complex than previously believed. Lead author Sean Gallen, an assistant professor of geosciences at CSU, explains that mountain building is a fundamental process of Earth’s behavior. However, this study suggests that our understanding … Read more

Antarctic ocean circulation slowing ahead of schedule

New research indicates that the circulation of waters to the deepest parts of the ocean surrounding Antarctica, driven by climate change, is occurring earlier than expected. The accelerated melting of Antarctic ice and rising temperatures, primarily caused by greenhouse gas emissions, are predicted to have a significant impact on the global network of ocean currents, … Read more

Banded iron formations may Have triggered volcanic eruptions

New research from Rice University has revealed that banded iron formations, characterized by visually striking layers of burnt orange, yellow, silver, brown, and blue-tinged black, may have triggered some of the largest volcanic eruptions in Earth’s history. These sedimentary rocks contain iron oxides that settled at the bottom of ancient oceans, forming dense layers that … Read more

Climate change causes earlier spring and longer summers in lakes

A recent comprehensive analysis of lake temperatures provides further confirmation of the seasonal alterations caused by climate change. The study, published in Nature Communications, utilizes historical and modeled lake temperature data to examine the timing of typical spring and autumn conditions across lakes worldwide. The research reveals the extent of seasonal shifts in different regions … Read more

Coastal ecosystems play important role in climate mitigation

A team of international researchers, led by Australia’s Southern Cross University, has revealed new insights into the greenhouse gas budget of coastal ecosystems worldwide. Their study, published on May 22 in Nature Climate Change, demonstrates that coastal ecosystems act as a net greenhouse gas sink for carbon dioxide (CO2), but the emissions of methane (CH4) … Read more

Scientists propose new way to monitor glaciers using sound

Monitoring glacial runoff using acoustic signals presents a cost-effective and accessible alternative to existing methods. With glaciers melting rapidly and causing significant sea-level rise and outburst floods, it is crucial to track the meltwater contribution to oceans and freshwater resources worldwide, as well as monitor the risk of glacial flooding. However, glacio-hydrological monitoring can be … Read more

New evidence suggests wildfires devastated terrestrial ecosystems during the end-Permian mass extinction

The end-Permian mass extinction (EPME) that occurred approximately 252 million years ago was a catastrophic event, resulting in the devastating loss of approximately 81% of marine species and 89% of terrestrial species. New research conducted by a collaboration between the Nanjing Institute of Geology and Paleontology of the Chinese Academy of Sciences (NIGAPS), Nanjing University, … Read more

Climate change could leave millions of people vulnerable to dangerous heat

New research published in the journal Nature Sustainability suggests that current climate policies will result in over a fifth of the global population being exposed to dangerously hot temperatures by 2100.
