Microplastic pollution increases sea foam height and stability      (via sciencedaily.com)     Original source 

Researchers examine the specific impacts of microplastics on the geophysics of sea foam formation in the critical zone where water meets air in the top layer of the ocean. They devised two simulations for their work -- a column filled with sea water injected with air and a laboratory-scale breaking wave channel to test the impacts of wave height on sea foam in the surface microlayer -- and tested their effects on sea foam formation, stability, and duration.

Weather experts discover new effect of storm -- in a teacup      (via sciencedaily.com)     Original source 

A new study reveals that Storm Ciaran cut an invisible path of mayhem across southern Britain last autumn, destroying any possibility that 20 million people could have a proper cup of tea at breakfast. The storm's record-breaking low pressure meant the boiling point of water was below the crucial 100 degrees Celsius required for a decent cuppa.

Ancient microbes offer clues to how complex life evolved      (via sciencedaily.com)     Original source 

Researchers have discovered that a single-celled organism, a close relative of animals, harbors the remnants of ancient giant viruses woven into its own genetic code. This finding sheds light on how complex organisms may have acquired some of their genes and highlights the dynamic interplay between viruses and their hosts.

Capturing carbon with energy-efficient sodium carbonate-nanocarbon hybrid material      (via sciencedaily.com)     Original source 

Carbon capture is a promising approach for mitigating carbon dioxide (CO2) emissions. Different materials have been used to capture CO2 from industrial exhaust gases. Scientists developed hybrid CO2 capture materials containing sodium carbonate and nanocarbon prepared at different temperatures, tested their performance, and identified the optimal calcination temperature condition. They found that the hybrid material exhibits and maintains high CO2 capture capacity for multiple regeneration cycles at a lower temperature, making it cost- and energy-effective.

Ground surface conditions impact speed and distance of leaking natural gas      (via sciencedaily.com)     Original source 

When natural gas leaks from a subsurface pipeline, a ground cover of water/snow saturation, asphalt paving or a combination of these can cause the gas to migrate away from the leak site up to three to four times farther than through dry soil, a new study has found. A research team also found that these surface conditions can impact the speed of the leaked gas, as well, traveling 3.5 times faster than an equivalent leak under dry soil conditions.

Oil and natural gas development in Permian is a key source of ozone pollution in Carlsbad Caverns National Park, study finds      (via sciencedaily.com)     Original source 

New research shows that ozone concentrations at Carlsbad Caverns National Park frequently exceed Environmental Protection Agency health standards, likely due to oil and natural gas development in the Permian Basin and surrounding region.

Local dragonflies expose mercury pollution patterns      (via sciencedaily.com)     Original source 

A new study has unveiled surprising findings about mercury pollution: where it comes from and how it moves through the environment vary significantly depending on the ecosystem. In drier regions, most mercury is deposited through rain and snow. In wetter, forested areas, gaseous mercury from the air sticks to leaves, which then fall and carry the toxin into the ground.

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.

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.

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.

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.

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.

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.
