Published Global study reveals health impacts of airborne trace elements
(via sciencedaily.com) Original source Researchers investigated global particulate matter, revealing health risks from trace elements.
Published Ice age climate analysis reduces worst-case warming expected from rising CO2
(via sciencedaily.com) Original source A detailed reconstruction of climate during the most recent ice age, when a large swath of North America was covered in ice, provides information on the relationship between CO2 and global temperature. Results show that while most future warming estimates remain unchanged, the absolute worst-case scenario is unlikely.
Published 38 trillion dollars in damages each year: World economy already committed to income reduction of 19 % due to climate change
(via sciencedaily.com) Original source Even if CO2 emissions were to be drastically cut down starting today, the world economy is already committed to an income reduction of 19% until 2050 due to climate change, a new study finds. These damages are six times larger than the mitigation costs needed to limit global warming to two degrees. Based on empirical data from more than 1,600 regions worldwide over the past 40 years, scientists assessed future impacts of changing climatic conditions on economic growth and their persistence.
Published Substantial global cost of climate inaction
(via sciencedaily.com) Original source Pioneering study reveals that limiting global warming to 1.5 degrees Celsius could reduce the global economic costs of climate change by two thirds. If warming continues to 3 degrees Celsius, global GDP will decrease by up to 10 percent -- with the worst impacts in less developed countries.
Published Paradox of extreme cold events in a warming world
(via sciencedaily.com) Original source The Warm Arctic-Cold Continent (WACC) phenomenon is the puzzling combination of Arctic warming and extreme coldness in specific mid-latitude regions. However, the progression of WACC events remains unclear amidst global warming. Scientists have now predicted a sharp decline in the WACC phenomenon post-2030s, affecting extreme weather events. These findings offer critical insights for communities, scientists, and policymakers to refine climate models and strategies and battle climate change.
Published Scientists develop framework to measure plastic emissions and bolster U.N. efforts to reduce pollution
(via sciencedaily.com) Original source Scientists have developed a framework for measuring plastic emissions akin to the global standard for measuring greenhouse gas emissions. The approach boosts identification of the biggest contributors to plastic pollution from local to national levels and could help improve strategies in reducing emissions worldwide if incorporated into a global agreement on plastic pollution. Using Toronto as a model, the researchers estimated that in one year alone, Toronto emitted nearly 4,000 tonnes of plastic pollution.
Published Huge database gives insight into salmon patterns at sea
(via sciencedaily.com) Original source A massive new analysis of high seas salmon surveys is enhancing the understanding of salmon ecology, adding details about where various species congregate in the North Pacific Ocean and their different temperature tolerances. The project integrates numerous international salmon studies from the North Pacific dating back to the 1950s.
Published Fires pose growing worldwide threat to wildland-urban interface
(via sciencedaily.com) Original source Fires that devastate wildland-urban interface areas are becoming more common around the globe, a trend that is likely to continue for at least the next two decades, new research finds. Such fires are especially dangerous, both because they imperil large numbers of people and because they emit far more toxins than forest and grassland fires.
Published Plastic pollution can kill variety of ocean embryos
(via sciencedaily.com) Original source High levels of plastic pollution can kill the embryos of a wide range of ocean animals, new research shows.
Published Yellowstone Lake ice cover unchanged despite warming climate
(via sciencedaily.com) Original source While most lakes around the world are experiencing shorter durations of ice cover, the length of time that Yellowstone Lake is covered by ice each year has not changed in the past century, possibly due to increased snowfall.
Published Most countries struggle to meet climate pledges from 2009
(via sciencedaily.com) Original source Nineteen out of 34 countries surveyed failed to fully meet their 2020 climate commitments set 15 years ago in Copenhagen, according to a new study by UCL researchers.
Published Global North energy outsourcing demands more attention
(via sciencedaily.com) Original source Manufacturing nations in the Global North are stockpiling energy and emission problems by outsourcing energy-intensive industrial processes to countries in the Global South.
Published Hidden threat: Global underground infrastructure vulnerable to sea-level rise
(via sciencedaily.com) Original source As sea levels rise, coastal groundwater is lifted closer to the ground surface while also becoming saltier and more corrosive. A recent study compiled research from experts worldwide showing that in cities where there are complex networks of buried and partially buried infrastructure, interaction with this shallower and saltier groundwater exacerbates corrosion and failure of critical systems such as sewer lines, roadways, and building foundations.
Published Millions of gamers advance biomedical research
(via sciencedaily.com) Original source 4.5 million gamers around the world have advanced medical science by helping to reconstruct microbial evolutionary histories using a minigame included inside the critically and commercially successful video game, Borderlands 3. Their playing has led to a significantly refined estimate of the relationships of microbes in the human gut. The results of this collaboration will both substantially advance our knowledge of the microbiome and improve on the AI programs that will be used to carry out this work in future.
Published GeoAI technologies for sustainable urban development
(via sciencedaily.com) Original source From heatwaves to pandemic diseases, the urban environments of the world face numerous challenges. Researchers are harnessing artificial intelligence (AI) and informatics to address emerging concerns related to environmental changes and urban growth.
Published New radar analysis method can improve winter river safety
(via sciencedaily.com) Original source Researchers have developed a way to use radar to detect open water zones and other changes in Alaska's frozen rivers in the early winter. The approach can be automated to provide current hazard maps and is applicable across the Arctic and sub-Arctic.
Published Where have all the right whales gone?
(via sciencedaily.com) Original source Marine researchers have mapped the density of one of the most endangered large whale species worldwide, the North Atlantic right whale, using new data to help avoid right whales' harmful exposure to commercial fisheries and vessel strikes. The resulting maps, spanning 20 years of whale observations, are publicly available to inform risk assessments, estimations of whale harm/disturbance, marine spatial planning, and industry regulations to mitigate risk to right whales.
Published Retention ponds can deliver a substantial reduction in tire particle pollution
(via sciencedaily.com) Original source New research has shown that the presence of wetlands and retention ponds alongside major highways led to an average reduction of almost 75% in the mass of tire wear particles being discharged to aquatic waters. The researchers say that while the number of retention ponds and wetlands in the UK is quite small, the study has international significance as to the most effective ways to mitigate against the potential impacts of tire pollution on a global scale.
Published Oceanographers uncover the vital role of mixing down of oxygen in sustaining deep sea health
(via sciencedaily.com) Original source Oceanographers have shown for the first time the important role of the 'mixing down' of oxygen in maintaining healthy conditions in the deep waters.
Published Africa's iconic flamingos threatened by rising lake levels
(via sciencedaily.com) Original source It is one of the world's most spectacular sights -- huge flocks or 'flamboyances' of flamingos around East Africa's lakes -- as seen in the film Out of Africa or David Attenborough's A Perfect Planet. But new research has revealed how the lesser flamingo is at danger of being flushed out of its historic feeding grounds, with serious consequences for the future of the species.
