Published Atmospheric and economic drivers of global air pollution
(via sciencedaily.com) Original source Carbon monoxide emissions from industrial production have serious consequences for human health and are a strong indicator of overall air pollution levels. Many countries aim to reduce their emissions, but they cannot control air flows originating in other regions. A new study looks at global flows of air pollution and how they relate to economic activity in the global supply chain.
Published How climate change will impact food production and financial institutions
(via sciencedaily.com) Original source Researchers have developed a new method to predict the financial impacts climate change will have on agriculture, which can help support food security and financial stability for countries increasingly prone to climate catastrophes.
Published Deep parts of Great Barrier Reef 'insulated' from global warming -- for now
(via sciencedaily.com) Original source Some deeper areas of the Great Barrier Reef are insulated from harmful heatwaves -- but that protection will be lost if global warming continues, according to new research.
Published Boreal forest and tundra regions worst hit over next 500 years of climate change, study shows
(via sciencedaily.com) Original source Modelling climate change over a 500 year period shows that much of the boreal forest, the Earth's northernmost forests and most significant provider of carbon storage and clean water, could be seriously impacted, along with tundra regions, treeless shrublands north of the boreal forest that play a significant role in regulating the Earth's climate.
Published Climate change threatens Antarctic meteorites
(via sciencedaily.com) Original source Antarctica harbors a large concentration of meteorites imbuing the icy continent with an unparalleled wealth of information on our solar system. However, these precious meteorites are rapidly disappearing from the ice sheet surface due to global warming, according to a new study.
Published Ocean waves propel PFAS back to land
(via sciencedaily.com) Original source A new study reveals that PFAS re-emit into the air from crashing ocean waves at levels comparable to or greater than other sources, establishing a cyclical transport process for these 'forever chemicals' between land and sea.
Published Dinosaur study challenges Bergmann's rule
(via sciencedaily.com) Original source A new study calls into question Bergmann's rule, an 1800s-era scientific principle stating that animals in high-latitude, cooler climates tend to be larger than close relatives living in warmer climates.
Published Heat stress from ocean warming harms octopus vision
(via sciencedaily.com) Original source While climate change has led to an increase in the abundance of octopuses, heat stress from projected ocean warming could impair their vision and impact the survivability of the species.
Published Four in five bird species cannot tolerate intense human pressures
(via sciencedaily.com) Original source In a recent study, researchers found that 78% of the world's bird species do not thrive in the most modified human-dominated environments. These species are also most likely to have declining populations.
Published Ocean floor a 'reservoir' of plastic pollution
(via sciencedaily.com) Original source New science has taken a deep dive into plastic waste, providing the first estimate of how much ends up on the sea floor.
Published Rusty-patched bumblebee's struggle for survival found in its genes
(via sciencedaily.com) Original source The rusty-patched bumblebee, once common in the United States, has declined from about 90% of its former range. Researchers conducted the first range-wide genetic study of the endangered species to inform recovery efforts.
Published Adult fish struggle to bounce back in marine protected areas
(via sciencedaily.com) Original source Many marine protected areas are falling short of their most basic purpose: to rebuild struggling fish populations. In a new study, scientists looked at the age breakdown of reef fish in marine protected areas for the first time. They discovered in almost all of them, adult fish populations -- vital to spawning the next generation -- have either flatlined or declined.
Published Demand for critical minerals puts African Great Apes at risk
(via sciencedaily.com) Original source A recent study shows that the threat of mining to the great ape population in Africa has been greatly underestimated.
Published More social birds are more adventurous feeders
(via sciencedaily.com) Original source A new study has found that birds that are more social are more likely to use novel sources of food.
Published Groundbreaking research in groundwater's role in ecosystem sustainability
(via sciencedaily.com) Original source Until now, groundwater -- a critical water resource around the globe, especially in dry regions -- has been largely unstudied in its importance and role in sustaining ecosystems. New groundbreaking research examines the relationship between groundwater and ecosystems across California.
Published New step in tectonic squeeze that turns seafloor into mountains
(via sciencedaily.com) Original source Researchers describe zircons from the Andes mountains of Patagonia. Although the zircons formed when tectonic plates were colliding, they have a chemical signature associated with when the plates were moving apart. The researchers think that the unexpected signature could be explained by the mechanics of underlying tectonic plates that hasn't yet been described in other models.
Published A new estimate of U.S. soil organic carbon to improve Earth system models
(via sciencedaily.com) Original source Emory environmentals scientist combined field-level data with machine-learning techniques to estimate soil organic carbon at the U.S. scale, another step toward providing more accurate baseline data to improve Earth system models for climate change.
Published Scientists' urgent call: End destruction and forge a just, sustainable future
(via sciencedaily.com) Original source An international team of scientists published a study emphasizing the urgent need to align political will, economic resources, and societal values to ensure a more sustainable and equitable world. The review summarizes the grave threats facing the planet but rejects a 'doom and gloom' philosophy. They advocate a global cultural shift that elevates kinship with nature and communal well-being, underpinned by the recognition of Earth's finite resources and the interconnectedness of its inhabitants.
Published How and why animals can live alongside humans
(via sciencedaily.com) Original source New research suggests animals can thrive in human-dominated environments by being expert judges of risk. Researchers examined the behavior of great-tailed grackles, a bird species successfully invading much of urban North America, showing that the dispersing males shy away from risk, which is a characteristic the researchers show is well-suited to chaotic environments like cities. These findings provide unique insight into how and why animals and humans can coexist.
Published When did the chicken cross the road? New evidence from Central Asia
(via sciencedaily.com) Original source An international team of scholars present the earliest clear archaeological and biomolecular evidence for the raising of chickens for egg production, based on material from 12 archaeological sites spanning one and a half millennia. The research indicates that the domestic chicken, now a staple in diets around the world, is not as ancient as previously thought.
