Human pressure on the world’s oceans accelerated sharply at the start of the 21st century and shows no sign of slowing, according to a comprehensive new analysis on the state of the ocean.
Sometimes the most unrelated things can produce the most innovative results. Take, for instance, aikido—a Japanese martial art that can be translated as the “way of unifying energy”—and paleoclimatology, a scientific field examining climate evolution.
New automotive technology that promises enhanced fuel efficiency may have a serious downside, including significant climate and public health impacts, according to research from the University of Georgia College of Engineering.
A new study of nearly every delta on the planet shows how river delta shapes and sizes around the world are changing due to human activity—both for the good and bad.
A trio of researchers from Aarhus University, Agroscope, Wädenswil and Vetagro Sup, France, Marcy l’étoile has published a Policy Forum piece in the journal Science calling for an overhaul of the regulatory frameworks that define the ways that pesticides can be used. Christopher Topping, Annette Aldrich and Philippe Berny suggest that the current system is outdated and needs to be changed because the current system is allowing more environmental damage than need be.
The waters of Puget Sound support many species, including mussels, salmon and killer whales. But researchers know that runoff from land in the urbanized areas might contain chemicals that could harm these creatures, even if it’s not always clear which chemicals are the most harmful.
In the wake of a devastating wildfire, burnt land has a respite before the next blaze. But until now, no one has known just how long that effect lasted across the US West. Researchers from the University of Colorado Denver and Portland State looked into the increasing rates and intensity of fires in the U.S. West, like Colorado’s Hayman Fire and California’s Camp Fire, are up tenfold over the last 40 years. They wanted to know, once the shrubs, trees and other woody fuels have burned up, how long before the next one?
About 80 percent of water systems across the country use a disinfectant in drinking water that can lead to undesirable byproducts, including chloroform. There is an alternative, but many cities have been afraid to use it.
When Hurricane Harvey slammed into the Texas coast in 2017, displaced residents flocked inland, trying to rebuild their lives in the disaster’s aftermath. Within decades, the same thing could happen at a much larger scale due to rising sea levels, says a new study led by USC Computer Science Assistant Professor Bistra Dilkina.
Permafrost, the perennially frozen subsoil in Earth’s northernmost regions, has been collecting and storing plant and animal matter since long before the last Ice Age. The decomposition of some of this organic matter naturally releases carbon dioxide (CO2) into the atmosphere year-round, where it is absorbed by plant growth during the warmer months.
A new study shows that air pollutants from the smoke of fires from as far as Canada and the southeastern U.S. traveled hundreds of miles and several days to reach Connecticut and New York City, where it caused significant increases in pollution concentrations.
A new report published in Nature Sustainability this week examines the potential impacts on food production of zero budget natural farming, a farming system that is sweeping India.
Despite reports that global emissions of the potent greenhouse gas hydrofluorocarbon (HFC) were almost eliminated in 2017, an international team of scientists, led by the University of Bristol, has found atmospheric levels growing at record values.
New research has found preparing land for palm oil plantations and the growth of young plants causes significantly more damage to the environment, emitting double the amount of greenhouse gases than mature plantations.
A new study in the journal Nature Sustainability overturns long-held interpretations of the role humans played in shaping the American landscape before European colonization. The findings give new insight into the rationale and approaches for managing some of the most biodiverse landscapes in the eastern U.S.
A scientific paper published in 1985 was the first to report a burgeoning hole in Earth’s stratospheric ozone over Antarctica. Scientists determined the cause to be ozone-depleting substances—long-lived artificial halogen compounds. Although the ozone-destroying effects of these substances are now widely understood, there has been little research into their broader climate impacts.
Excess nitrogen is a major threat to water quality in coastal waters worldwide. Found in treated wastewater, farm and lawn fertilizers and combustion exhaust, it fuels blooms of algae that shade submerged grasses and suck oxygen from the water when they die and decay.
River flow is reduced in areas where forests have been planted and does not recover over time, a new study has shown. Rivers in some regions can completely disappear within a decade. This highlights the need to consider the impact on regional water availability, as well as the wider climate benefit, of tree-planting plans.
Despite the prominent health threat posed by fine particulate pollution, fundamental aspects of its formation and evolution continue to elude scientists.
On an island famed as Australia’s “Galapagos” for its unique and abundant wildlife, rescuers are racing to save rare animals in a bushfire-ravaged landscape.
The essential roles that microbes play in deep-sea ecosystems are at risk from the potential environmental impacts of mining, a new paper in Limnology and Oceanography reports. The study reviews what is known about microbes in these environments and assesses how mining could impact their important environmental roles.
A new study suggests global warming effect is underestimated, but climate scientists say more research is needed.
