Published Scientists discover missing piece in climate models
(via sciencedaily.com)
Original source 
As the planet continues to warm due to human-driven climate change, accurate computer climate models will be key in helping illuminate exactly how the climate will continue to be altered in the years ahead.
Published Producing hydrogen and fertilizer at the same time
(via sciencedaily.com)
Original source 
This new concept could allow the needs of previously separate industries to be combined: the production of hydrogen and the production of fertilizer.
Published Loss of oxygen in lakes and oceans a major threat to ecosystems, society, and planet
(via sciencedaily.com)
Original source 
Oxygen is a fundamental requirement of life, and the loss of oxygen in water, referred to as aquatic deoxygenation, is a threat to life at all levels. In fact, researchers describe how ongoing deoxygenation presents a major threat to the stability of the planet as a whole.
Published Wildfire smoke has a silver lining: It can help protect vulnerable tree seedlings
(via sciencedaily.com)
Original source 
Forest scientists studying tree regeneration have found that wildfire smoke comes with an unexpected benefit: It has a cooling capacity that can make life easier for vulnerable seedlings.
Published Study examines urban forests across the United States
(via sciencedaily.com)
Original source 
Tree-planting campaigns have been underway in the United States, especially in cities, as part of climate mitigation efforts given the many environmental benefits of urban forests. But a new study finds that some areas within urban forests in the U.S., may be more capable than trees growing around city home lawns in adapting to a warmer climate.
Published Scientists find new way global air churn makes particles
(via sciencedaily.com)
Original source 
Researchers have discovered a new mechanism by which particles are formed around the globe.
Published Complex impact of large wildfires on ozone layer dynamics
(via sciencedaily.com)
Original source 
In a revelation highlighting the fragile balance of our planet's atmosphere, scientists have uncovered an unexpected link between massive wildfire events and the chemistry of the ozone layer. Using satellite data and numerical modeling, the team discovered that an enormous smoke-charged vortex nearly doubles the southern hemispheric aerosol burden in the middle stratosphere of the Earth and reorders ozone depletion at different heights. This study reveals how wildfires, such as the catastrophic 2019/20 Australian bushfires, impact the stratosphere in previously unseen ways.
Published High and low tide cause low and high methane fluxes
(via sciencedaily.com)
Original source 
Methane, a strong greenhouse gas that naturally escapes from the bottom of the North Sea, is affected by the pressure of high or low tide. Methane emissions from the seafloor can be just easily three times as much or as little, depending on the tide, according to a new study.
Published Unprecedented warming threatens Earth's lakes and their ecosystems
(via sciencedaily.com)
Original source 
Lakes, with their rich biodiversity and important ecological services, face a concerning trend: rapidly increasing temperatures. A recent study by limnologists and climate modelers reveals that if current anthropogenic warming continues until the end of this century, lakes worldwide will likely experience pervasive and unprecedented surface and subsurface warming, far outside the range of what they have encountered before.
Published Scientists create computer program that 'paints' the structure of molecules in the style of Piet Mondrian
(via sciencedaily.com)
Original source 
Scientists have created a computer program that 'paints' the structure of molecules in the style of famous Dutch artist, Piet Mondrian. Researchers are opening eyes and minds to the beauty of molecular structure, as well as posing new questions about the form and function of the molecules themselves.
Published Forest carbon storage has declined across much of the Western U.S., likely due to drought and fire
(via sciencedaily.com)
Original source 
Forests have been embraced as a natural climate solution, due to their ability to soak up carbon dioxide from the atmosphere as they grow, locking it up in their trunks, branches, leaves, and roots. But a new study confirms widespread doubts about the potential for most forests in the Western US to help curb climate change. The paper analyzed trends in carbon storage across the American West from 2005 to 2019.
Published Study finds health risks in switching ships from diesel to ammonia fuel
(via sciencedaily.com)
Original source 
Without additional regulation, burning ammonia in ship engines could cause serious impacts on air quality that could result in more than 600,000 additional premature deaths per year, according to new research.
Published Scientists call for 'major initiative' to study whether geoengineering should be used on glaciers
(via sciencedaily.com)
Original source 
Scientists have released a landmark report on glacial geoengineering -- an emerging field studying whether technology could halt the melting of glaciers and ice sheets as climate change progresses.
Published New solutions to keep drinking water safe as pesticide use skyrockets worldwide
(via sciencedaily.com)
Original source 
Water scientists have proposed a more effective method of removing organic pesticides from drinking water, reducing the risk of contamination and potential health problems.
Published Hydrogen flight looks ready for take-off with new advances
(via sciencedaily.com)
Original source 
The possibility of hydrogen-powered flight means greater opportunities for fossil-free travel, and the technological advances to make this happen are moving fast. New studies show that almost all air travel within a 750-mile radius (1200 km) could be made with hydrogen-powered aircraft by 2045, and with a novel heat exchanger currently in development, this range could be even further.
Published Mapping the world's fungi from air samples
(via sciencedaily.com)
Original source 
Researchers have found that the key to a quick and cost-effective mapping of biodiversity has been right in front of our eyes all along, but at the same time invisible -- i.e., in the air that surrounds us.
Published Air pollution harms pollinators more than pests, study finds
(via sciencedaily.com)
Original source 
Pollinators experienced a 39-percent decline in foraging efficiency after being exposed to elevated air pollution levels. In contrast, plant-eating aphids and other pests were not significantly impacted.
Published Targeted home systems to remove PFAS more cost-effective than system-wide solutions
(via sciencedaily.com)
Original source 
PFAS, the potentially cancer-causing chemicals known as 'forever chemicals', have become an increasing concern in home drinking water. Solutions to reduce the risk of exposure range from mandated municipal-level water treatment to under-the-sink home treatment systems. But are consumers willing to foot the bill for an additional treatment system to help municipalities meet new federal drinking water regulations? Researchers found that they are, if it helps reduce the risk and fits their budget.
Published Could lead overcome reverse current and advance a green hydrogen economy?
(via sciencedaily.com)
Original source 
Researchers developed a catalyst that enhances the stability of alkaline water electrolysis systems.
Published New study provides enhanced understanding of tropical atmospheric waves
(via sciencedaily.com)
Original source 
Findings has critical implications for predicting extreme weather events such as hurricanes and heavy rainfall.
