Phys.org / Permian marine mass extinction linked to volcanism-induced anoxia
Mass extinctions are rapid global decreases in Earth's biodiversity, with five key events identified over the planet's history, arguably the most famous of which occurred ~66 million years ago during the Cretaceous, which ...
Phys.org / Arabia's alluvial fans grow and decay with Earth's orbital cycles
Erosion of Earth's topography entrains sediment in rivers flowing across mountains, canyons and other naturally steep landscapes within the catchment. This silt, sand and gravel is transported variably by suspension in the ...
Phys.org / Marine heat waves: Why the East Sea experienced extreme conditions in 2021
Extreme environmental events are becoming an ever more pressing concern with the continued stresses of climate change, both on land and in the marine realm. While terrestrial heat waves tend to occur over a few days, those ...
Phys.org / Reservoir construction may be reducing carbon storage in ocean sediments
Carbon storage has been a key focus in recent years to draw down natural and anthropogenic sources of carbon dioxide and help the fight against global warming, and particularly focuses on terrestrial forests and soils, as ...
Phys.org / Carbon neutrality likely to increase extreme weather events by 2050, finds study
Climate modeling based upon Earth's current greenhouse gas emissions trajectory predicts a worst-case scenario of 4.3°C warming of the planet by 2100 if sufficient measures are not implemented. While the Paris Climate Agreement ...
Phys.org / Climate change increasing likelihood of extreme snowfall in the French Alps, research suggests
Global warming is often cited as having a negative impact on snow and ice melt in cold regions, yet new research published in The Cryosphere has suggested that extreme snowfall events may be a feature of some locations at ...
Phys.org / Plant health as a new effective monitoring system for volcanic activity
Plants have a symbiotic relationship with their surrounding environment, being a vital indicator of the overall health of the landscape, as well as significant changes within it. One such driver of plant response is gas emissions, ...
Phys.org / Global warming–induced sea level changes could increase earthquake risk
Earthquakes often occur along plate boundaries, when sudden movements of the "stuck" plates release elastic strain energy, sending out seismic waves that result in the ground shaking familiar to many worldwide. More rarely, ...
Phys.org / Seagrass decline poses issues for carbon storage projects
Climate change is an ever-pressing concern, with innovative ways to remove excess carbon from the atmosphere a continued focus of scientists. One such carbon sequestration method turns to an unlikely sink—seagrass—a marine ...
Phys.org / Deforestation across the 'Maritime Continent' is making El Niño-Southern Oscillation more unpredictable, finds study
El Niño-Southern Oscillation (ENSO) is a climate phenomenon occurring every 2–7 years in the tropical Pacific Ocean, associated with changes in air pressure east to west.
Phys.org / Arctic Ocean soundscapes reveal changes in mammal populations in response to climate change
While the sounds of our oceans may be familiar to us through the lens of nature documentaries, from the haunting calls of whales to the barks of some fish, this acoustic environment can provide a wealth of knowledge to scientists ...
Phys.org / Volcanic eruptions found to dampen Indian Ocean El Niño events for up to 8 years
Volcanic eruptions occurring in tropical regions (23°N/S of the equator) have been linked to abrupt disruption of global-scale climate cycles in the Indian Ocean over the last 1 million years in new research published in ...
Phys.org / Declining Bering Sea ice linked to increasing wildfire hazard in northeast China
China has been making strides in recent years to reduce air pollution, including fitting filters in coal-fired power stations to remove sulfur dioxide from emissions, a molecule that reacts with other compounds in the atmosphere ...
Phys.org / Anthropogenic aerosols could delay enhanced monsoon precipitation by decades
Earth's atmosphere contains fine particles suspended in the air, known as aerosols, occurring from natural sources, such as dust from deserts, volcanic ash, smoke from forest fires, sea salt from ocean spray and organic compounds ...
Phys.org / Atmospheric microplastic transport predominantly derived from oceans, study finds
Microplastics in our natural environments are of increasing concern as these tiny particles (
