Engineers 'symphonize' cleaner ammonia production      (via sciencedaily.com)     Original source 

Among the many chemicals we use every day, ammonia is one of the worst for the atmosphere. The nitrogen-based chemical used in fertilizer, dyes, explosives and many other products ranks second only to cement in terms of carbon emissions, due to the high temperatures and energy needed to manufacture it. But by improving on a well-known electrochemical reaction and orchestrating a 'symphony' of lithium, nitrogen and hydrogen atoms, engineers have developed a new ammonia production process that meets several green targets.

Exposure to common environmental carcinogens linked to decreased lifespan happiness      (via sciencedaily.com)     Original source 

Researchers found that exposure to environmental carcinogens and psychological distress is significantly linked to decreased happy life expectancy, a measure of the lifespan during which an individual experiences subjective emotional wellbeing. These findings suggest that developing public health policies to reduce exposure to these chemicals could help people live longer, happier lives.

Melting glaciers in a warmer climate provide new ground for invasive species      (via sciencedaily.com)     Original source 

In 2022 and 2023, biologists from research institutes in the UK and the Falkland Islands led two expeditions to South Georgia to study the impacts of invasive species on this cold and rugged sub-Antarctic island. They report that several invasive plants and invertebrates rapidly colonized the new ground exposed by melting glaciers, leaving few pristine areas for native species. With ongoing climate change, more research is needed across the world to understand how invasive species impact the fragile ecosystems that develop after glacier melting.

Manganese plays a surprising role in soil carbon sequestration      (via sciencedaily.com)     Original source 

A recent study reveals an unexpected link between manganese -- a naturally occurring mineral -- and increased carbon emissions from high-latitude boreal forests. The study uncovers how manganese increases carbon emissions from boreal forest soil, over time, challenging conventional understanding of the role of manganese in the carbon cycle.

Blueprint for mandating indoor air quality for public buildings in form of standards      (via sciencedaily.com)     Original source 

A group of international experts has presented a blueprint for national indoor quality standards for public buildings. The experts addressed setting standards for three key indoor pollutants -- carbon dioxide, carbon monoxide, and PM2.5 (particles so small they can lodge deep in the lungs and enter the bloodstream) -- and ventilation rate.

How built environment correlates with risk of cardiovascular disease      (via sciencedaily.com)     Original source 

Researchers have studied hundreds of elements of the built environment, including buildings, green spaces, pavements and roads, and how these elements relate to each other and influence coronary artery disease in people living in these neighborhoods. Their findings show that these factors can predict 63% of the variation in the risk of coronary heart disease from one area to another.

Going 'back to the future' to forecast the fate of a dead Florida coral reef      (via sciencedaily.com)     Original source 

How coral populations expand into new areas and sustain themselves over time is limited by the scope of modern observations. Going back thousands of years, a study provides geological insights into coral range expansions by reconstructing the composition of a Late Holocene-aged subfossil coral death assemblage in an unusual location in Southeast Florida and comparing it to modern reefs throughout the region. Findings offer a unique glimpse into what was once a vibrant coral reef assemblage and discover if history can repeat itself in the face of climate change.

How extratropical ocean-atmosphere interactions can contribute to the variability of jet streams in the Northern Hemisphere      (via sciencedaily.com)     Original source 

Ocean-atmosphere coupling, the exchange in energy between the ocean and atmosphere, influences teleconnection patterns, the climate effects across vast geographical areas. However, its impact outside the tropics is unclear. A group of researchers examined the effect of ocean coupling on atmospheric circulation patterns in the Northern Hemisphere. They found that extratropical ocean-atmosphere coupling enhances teleconnection patterns and causes more meandering westerly jet streams, which are linked to extreme weather events.

Artificial reef designed by MIT engineers could protect marine life, reduce storm damage      (via sciencedaily.com)     Original source 

Engineers designed an 'architected' reef that can mimic the wave-buffering effects of natural reefs while providing pockets for marine life. The sustainable and cost-saving structure could dissipate more than 95 percent of incoming wave energy using a small fraction of the material normally needed.

Climate change policies lose popularity when combined with pausing regulations or social justice      (via sciencedaily.com)     Original source 

Legislators love bundling things together. It lets them accomplish more with less hassle and attempt to make legislation more appealing to a broader group. But a new study suggests that this can sometimes backfire. The authors found that pairing climate policies with other policies does not necessarily increase their popular appeal, and can actually reduce public support.

Food matters: Healthy diets increase the economic and physical feasibility of 1.5°C      (via sciencedaily.com)     Original source 

A global shift to a healthier, more sustainable diet could be a huge lever to limit global warming to 1.5 C, researchers find. The resulting reduction of greenhouse gas emissions would increase the available carbon budget compatible with limiting global warming to 1.5 C, and allow to achieve the same climate outcome with less carbon dioxide removal and less stringent CO2 emissions reductions in the energy system. This would also reduce emission prices, energy prices and food expenditures.
