Published Companies ignoring climate risks get punished by markets, new study reveals
(via sciencedaily.com) Original source Companies that proactively manage climate risks boost their valuations, while those with a passive stance are discounted in the equity market, according to new research.
Published AI writing, illustration emits hundreds of times less carbon than humans, study finds
(via sciencedaily.com) Original source A group of scholars calculated the amount of energy used by AI tools for the tasks of writing and illustrating and compared it to the average amount of energy humans use for the same processes. Their results showed artificial intelligence results in hundreds of times less carbon emissions than humans. This does not mean, however, that AI can or should replace humans in those tasks, simply that its energy usage is less. The better approach is a partnership between humans and AI, the authors write.
Published Australia on track for unprecedented, decades-long megadroughts
(via sciencedaily.com) Original source Australia could soon see megadroughts that last for more than 20 years, according to new modelling. The researchers' bleak findings are before factoring in human impact on the climate since the Industrial Revolution. According to the scientists, the findings paint a worrying picture of future droughts in Australia that are far worse than anything in recent experience.
Published Building blocks for greener energy: Reconfigurable elastic metasurface
(via sciencedaily.com) Original source Energy harvesting, an eco-friendly technology, extends beyond solar and wind power in generating electricity from unused or discarded energy in daily life, including vibrations generated by passing car engines or trains. Recent intriguing research has been announced, aiming to enhance the efficiency of energy harvesting using a new type of metasurface that can be reconfigured, resembling the assembly of LEGO bricks.
Published Older trees help to protect an endangered species
(via sciencedaily.com) Original source The oldest trees in the forest help to prevent the disappearance of endangered species in the natural environment, according to a new study. This is the case of the wolf lichen -- threatened throughout Europe --, which now finds refuge in the oldest trees in the high mountains of the Pyrenees. This study reveals for the first time the decisive role of the oldest trees in the conservation of other living beings thanks to their characteristic and unique physiology.
Published Biofilm-resistant glass for marine environments
(via sciencedaily.com) Original source Engineers have created ultraviolet (UV) rays-emitting glass that can reduce 98% of biofilm from growing on surfaces in underwater environments.
Published Chemistry researchers modify solar technology to produce a less harmful greenhouse gas
(via sciencedaily.com) Original source Researchers are using semiconductors to harvest and convert the sun's energy into high-energy compounds that have the potential to produce environmentally-friendly fuels.
Published Gloom and doom warnings about climate change do not work
(via sciencedaily.com) Original source How do you spread a message about climate change? According to an international study involving 59,000 participants, some tactics may actually reduce support.
Published 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.
Published 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.
Published Simple equations clarify cloud climate conundrum
(via sciencedaily.com) Original source New analysis based on simple equations has reduced uncertainty about how clouds will affect future climate change.
Published 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.
Published 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.
Published New approach to monitoring freshwater quality can identify sources of pollution, and predict their effects
(via sciencedaily.com) Original source Analysing the diversity of organic compounds dissolved in freshwater provides a reliable measure of ecosystem health, say scientists.
Published 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.
Published Parental avoidance of toxic exposures could help prevent autism, ADHD in children, new study shows
(via sciencedaily.com) Original source Researchers have found that parents with chemical intolerance are more likely to report children with autism and ADHD.
Published Open waste burning linked to air pollution in Northwestern Greenland
(via sciencedaily.com) Original source A case study on the effects of open waste burning on air quality in Northwestern Greenland calls attention to the importance of no-one-left-behind sustainable air quality monitoring in the Arctic region.
Published Study unlocks the power of visible light for sustainable chemistry
(via sciencedaily.com) Original source A breakthrough in sustainable molecular transformations has been announced. Chemists have developed an important way to harness the power of visible light to drive chemical processes with greater efficiencies, offering a greener alternative to traditional methods.
Published 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.
Published 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.
