Scientists have uncovered new details of how ice forming below the ocean surface in Antarctica provides cold dense water that sinks to the seabed in an important aspect of global water circulation.
Mathematical models that predict policy-driving scenarios - such as how a new pandemic might spread or the future amount of irrigation water needed worldwide - may be too complex and delivering ‘wrong’ answers, a new study reveals.
Mechanical engineer Jennifer Wade is leading two federally funded projects that are addressing the critical question of how to remove greenhouse gases from the atmosphere, thus slowing the devastating effects of global climate change. It's part of a national effort called the Carbon Negative Earthshot: Being able to remove carbon at $100 a ton at a scale of a million tons per year. That's a difficult task, Wade says, but it's not an insurmountable one.
Climate change is causing the Arctic Ocean’s sea ice to melt away.
Struggling salmon populations could get some help from the sky. A Washington State University study showed that drone photography of the Wenatchee River during spawning season can be effective in estimating the number of rocky hollows salmon create to lay their eggs, also called “redds.”

Despite improvements by meatpackers to keep their supply chains free of cattle grazed on protected or illegally deforested lands, many slaughterhouses in Brazil — the world's top beef exporter — continue to purchase illegally pastured animals on a large scale. A new study published Oct. 18 in the journal Conservation Letters underscores the depth of the problem.
A major new project will help benchmark biodiversity change in the Arctic Ocean and guide conservation efforts by identifying unique species and assessing their extinction risk.
Thawing permafrost soils in the rapidly warming Arctic will emit as much greenhouse gas as large industrial nations by the end of this century, according to a University of Alberta researcher involved in an international study that stresses to policy makers that it’s not too late to act to stabilize the climate and avoid exceeding temperature targets.
By the end of this century, permafrost in the rapidly warming Arctic will likely emit as much carbon dioxide and methane into the atmosphere as a large industrial nation, and potentially more than the U.S. has emitted since the start of the industrial revolution.
Stumbling upon a new source of underwater caffeine was just an added bonus of a new study examining the impact of chemical compounds that corals release into the seawater.
Alien floras in regions that were once occupied by the same European power are, on average, more similar to each other compared to outside regions and this similarity increases with the length of time a region was occupied. This is the conclusion of a study by an international team of researchers led by Bernd Lenzner and Franz Essl from the University of Vienna, which was recently published in the scientific journal "Nature Ecology and Evolution".
As greenhouse gases bubble up across the rapidly thawing Arctic, Sandia National Laboratories researchers are trying to identify other trace gases from soil microbes that could shed some light on what is occurring biologically in melting permafrost in the Arctic.Sandia bioengineer Chuck Smallwood and his team recently spent five days collecting lakebed soil and gas samples.
Type of litterfall, and the way water moves in and around tree islands are two attributes that helps them store carbon better than their marshy neighbors
A new study indicates previously unknown high altitude contests between two of America’s most sensational mammals – mountain goats and bighorn sheep – over access to minerals previously unavailable due to the past presence of glaciers which, now, are vanishing due to global warming.
Bumblebees don’t seem to keep memories for how sweet a flower was, but instead only remember if it was sweeter than another flower, according to researchers at Queen Mary University of London, along with an international team of scientists.
Good news in the report about the recovery of coral in Australia's Great Barrier Reef. However, this news is not a reason for dismissing the severe effect that climate change-induced ocean warming is bringing to coral reefs in the GBR and throughout the world, says Prof.
Climate change is resulting in sea level rise as ice on land melts and oceans expand. How much and how fast sea levels will rise in the near future will depend, in part, on the frequency of glacier calving events.
A team at the University of Exeter has shown experimentally for the first time, that hoverflies migrating during the spring orientate north.
Modern agriculture uses a lot of plastic, especially in the form of mulch film that farmers use to cover field soils. This keeps the soils moist for crops, suppresses weeds and promotes crop growth.
For his work helping to arrange that many-pieced, time-shifting puzzle, the Geological Society of America has named Florida State University Assistant Professor Richard Bono as the 2022 recipient of the Seth and Carol Stein Early Career Award in Geophysics and Geodynamics. Bono is the first person to receive the award.
A new study from the Lab of Fangqiong Ling at the McKelvey School of Engineering will help facilitate the exchange of data and results between engineers and medical researchers, leading to a more robust understanding of the relationships between viruses moving through the engineered world and diseases spreading through populations.
World-renowned scholars and researchers engaged in interdisciplinary dialogue on the challenges and prospects of next-generation energy development and applications at the HK Tech Forum on Carbon Neutrality and Sustainable Environment, hosted by Hong Kong Institute for Clean Energy and Hong Kong Institute for Advanced Study at City University of Hong Kong (CityU) from 5 to 8 October.
Scientists from the Immanuel Kant Baltic Federal University and Shirshov Institute of Oceanology of Russian Academy of Sciences described changes in conditions of bottom waters of the Atlantic during last 500 thousand years. As oceans plays an important role in formation of global climate, this information can help to understand contemporary changes and predict future variations in temperature and risks connected with them.
A new University of Washington-led study has found that even in remote, rarely visited national parks, the presence of even just a few humans impacts the activity of wildlife that live there. Nearly any level of human activity in a protected area like a national park can alter the behavior of animals there, the study found.
A new project will help to ensure sustainable fishing and aquaculture (fish farming) of Caribbean spiny lobsters.

A newly released State of the Birds report for the United States reveals a tale of two trends – one hopeful, one dire. Long-term trends of waterfowl show strong increases where investments in wetland conservation have improved conditions for birds and people. But data show birds in the U.S. are declining overall in every other habitat – forests, grasslands, deserts, and oceans.
Geoscientists develop new technique that reveals the health of coral reefs from space.
Two endemic species of the same flowering plant -- O nakaiana and O hexandra -- have distinctly different origins. Their study is based on molecular analysis of chloroplast samples of this genus taken from surrounding areas. The study demonstrates the complexity of floral speciation and distribution.
A first-of-its-kind study has shown adding eco-friendly ratings on menu items results in diners making choices which are kinder to the environment.
Sea-level rise and big storms are hammering coastal communities, causing increased flooding and land loss, saltwater intrusion, wetland loss/change, and impacts to local infrastructure.
Deep-water wave groups are known to be unstable and become rogue. Such unstable wave groups propagate independently regardless of interference. Results seem to support the concept of an unperturbed nonlinear water wave group focusing in the presence of counter-propagating waves, suggesting wave states are directional.
