Throughout history, important cities around the world have flourished along river banks. But rivers can also be destructive forces. They routinely flood, and on rare occasions, they can abruptly shift pathways.
During heavy storms, the normally stratified layers of water in ocean fjords get mixed, which leads to oxygenation of the fjord floor. But these storm events also result in a spike in methane emissions from fjords to the atmosphere.
The global food trade is often blamed for accelerating the destruction of biodiversity in poorer tropical countries, to fuel the appetites of richer nations for fruit, coffee, soybeans, beef, and palm oil.
If that lockdown goldfish is starting to lose its lustre, think twice before throwing it in the river or canal – the creatures may look innocent but their voracious appetite, tolerance for cold and have-a-go habits compared with native species can be catastrophic for local wildlife.
The start-up Running Tide wants to use kelp buoys to fight climate change. The plan might not work, but it’s still a preview of our climate future.
About 29 percent of the United States' population live in coastline counties—more than 41 million are in Atlantic counties. This high population density poses a critical challenge to sustainable developments in coastal areas.
Alleviating the urban heat-island effect through regulating urban landscape can improve human thermal comfort and living environment in urban residential areas. However, most previous studies focused on the single environmental factor of temperature, ignoring the actual human feeling of thermal ...
In the cold, choppy waters of Alaska's Resurrection Bay, all eyes were on the gray water, looking for one thing only. It wasn't a spout from humpback whales that power through this scenic fjord, or a sea otter lazing on its back, munching a king crab.
Scientists have recently confirmed that the world's lakes are rapidly losing oxygen. With a seven-year, whole-ecosystem study, a team of freshwater scientists at Virginia Tech has been one of the first to take the next step in asking: What does it mean for water quality that oxygen is declining ...

The world’s oceans are at their most acidic level for at least 26,000 years, according to a report from the World Meteorological Organisation (WMO) which made some striking warnings about climate change.
Based on an evaluation of over 500 academic articles, an international research team has traced the application of greening concepts in the context of Swedish planning and particularly in the Stockholm metropolitan region.
New research led by the University of Cambridge is the first to take a detailed image of an unusual pocket of rock at the boundary layer with Earth's core, some three thousand kilometers beneath the surface.
A team of researchers at the Indian Institute of Science, has analyzed YouTube videos captured by amateur elephant enthusiasts to learn more about how the animals respond when one of their herd members dies. Their paper is published in the journal Royal Society Open Science.
A new study provides a framework to boost crop growth by incorporating a strategy adopted from a fast-growing species of green algae. The algae, known as Chlamydomonas reinhardtii, contain an organelle called the pyrenoid that speeds up the conversion of carbon, which the algae absorb from the a ...
A new study published in Biological Conservation reviews a suite of published scientific research, providing evidence that conservation action can help species adapt to a changing climate.
Researchers from the Senckenberg Center for Human Evolution and Paleoenvironment at the University of Tübingen have identified fossils of a previously unknown crocodile species in Vietnam.
A SARS-CoV-2 test for bats using fecal samples could boost understanding of how wild animals transmit viruses to other animals and humans.
Mouse deer are among the smallest ruminants in the world. Today, they live in the tropics of Africa and Asia and are barely larger than hares. Males and females differ little in appearance. But that was not the case about eleven million years ago.
The Tibetan highlands have a special significance both as a grazing ecosystem and global carbon store. Furthermore, it plays a key role in the formation of the monsoon and supplying of potable water for a fifth of the earth's population.
Plants—they're just like us, with unique techniques for handling stress. To save one of the most important crops on Earth from extreme climate swings, scientists are mapping out plants' own stress-busting strategies.
No vertebrate (fish, mammal, bird, reptile, or amphibian) has ever had an odd number of limbs. Despite this "forbidden phenotype," some animals seem to use other body parts as a third or fifth "limb" to move from one place to another.
An unusual technique for catching scallops that was stumbled upon accidentally by scientists could potentially reduce some of the damage caused to our seabeds by fishing.
It’s no secret that Earth’s biodiversity is at risk. According to the International Union for the Conservation of Nature, 26% of all mammals, 14% of birds and 41% of amphibians are currently threatened worldwide, mainly due to human impacts such as climate change and development.
More than 98% of U.S. waters outside the central Pacific Ocean are not part of a marine protected area, and the ones that are tend to be "lightly" or "minimally" protected from damaging human activity, research led by Oregon State University shows.
Ants may be the unlikely heroes when it comes to better understanding the health of our planet in the midst of a climate crisis. In a paper published to Frontiers in Remote Sensing, a team of scientists, including those from NASA, have found a way to estimate the depth of snow from orbit using a ...
New research predicts that changes in mountain snowmelt will shift peak streamflows to much earlier in the year for the vast Colorado River Basin, altering reservoir management and irrigation across the entire region.
In Nigeria, about 90% of water available for drinking is sourced from boreholes, or deep, narrow wells that tap into naturally occurring underground water. A recent study in Environmental Toxicology & Chemistry found that microplastics (MPs) are abundant in the drinking water of these boreholes.
Most bottom-dwelling marine invertebrate animals, such as sponges, corals, worms and oysters, produce tiny larvae that swim in the ocean prior to attaching to the seafloor and transforming into juveniles.
Amphibians evolved from a fish ancestor that had functional lungs and bony lobed fins, which helped them become the first vertebrates to conquer land. Keeping these earlier trails, today’s frogs and toads also have larvae with gills that need an aquatic environment until they transform into air- ...
The European Commission (EC) has released an independently-researched report on the role of nature-based solutions (NbS) in the transition towards a nature positive economy.
Each winter, spring, and summer, extreme weather forecasters and researchers meet to test the latest, most promising severe weather forecast tools and innovations to see how they perform in real-world settings.
Wetlands across the globe are in danger of drowning from rising seas. But for decades, scientists held out hope that another aspect of climate change—rising carbon dioxide (CO2)—could trigger extra plant growth, enabling coastal wetlands to grow fast enough to outpace sea-level rise.
Aerosol particles can form and grow in Earth's upper troposphere in an unexpected way, reports the CLOUD collaboration in a paper published today in Nature. The new mechanism may represent a major source of cloud and ice seed particles in areas of the upper troposphere where ammonia is efficient ...
Storm surge, the massive mound of water that builds up and comes ashore during a hurricane, is often the deadliest and most destructive threat from these devastating storms.

Researchers from the German Centre for Integrative Biodiversity Research (iDiv), the Martin Luther University Halle-Wittenberg (MLU), Leipzig University and other institutions describe how to use this great potential for species pr ...
Once humans discovered how to tame fire, they began using it for heat and cooking as well as to scare away animals and to alter their environs, especially burning areas to plant and to restore grazing land
Much of the "excess heat" stored in the subtropical North Atlantic is in the deep ocean (below 700m), new research suggests.
Prescribed burning of ground-level shrubs, branches and leaves is a time-tested tool to help prevent wildland fires from getting out of control, but a team led by researchers at the University of California, Irvine suggests that the practice isn't used frequently enough.
New research modeling smoke from two recent megafires sets the stage for better forecasting of how emissions from these global-scale events will behave and impact temperatures.
A recent study confirms alarming declines in raptor populations in Kenya. Incidental poisoning is a major problem for vultures in particular, depriving ecosystems of the birds’ vital role as scavengers. Conservationists are working with communities to help species recover.
Agriculture, loss of habitat or wastewater effluents—human stressors negatively impact biodiversity in streams and rivers. Very little is known yet about the extent to which their capacity for self-purification and other essential ecosystem services are also impacted.
