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 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 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 Switch to green wastewater infrastructure could reduce emissions and provide huge savings according to new research
(via sciencedaily.com) Original source Researchers have shown that a transition to green wastewater-treatment approaches in the U.S. that leverages the potential of carbon-financing could save a staggering $15.6 billion and just under 30 million tons of CO2-equivalent emissions over 40 years.
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 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 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.
Published Rock permeability, microquakes link may be a boon for geothermal energy
(via sciencedaily.com) Original source Using machine learning, researchers have tied low-magnitude microearthquakes to the permeability of subsurface rocks beneath the Earth, a discovery that could have implications for improving geothermal energy transfer.
Published Tropical coral-infecting parasites discovered in cold marine ecosystems
(via sciencedaily.com) Original source Parasites thought only to infect tropical coral reefs have been discovered in a large variety of creatures in cold marine ecosystems along the Northeast Pacific, according to new research.
Published Pacific cities much older than previously thought
(via sciencedaily.com) Original source New evidence of one of the first cities in the Pacific shows they were established much earlier than previously thought, according to new research. The study used aerial laser scanning to map archaeological sites on the island of Tongatapu in Tonga, showing Earth structures were being constructed in Tongatapu around AD 300.
Published Novel UV broadband spectrometer revolutionizes air pollutant analysis
(via sciencedaily.com) Original source A research team has developed a broadband UV dual-comb spectrometer with which air pollutants can be continually measured and their reaction with the environment can be observed in real time.
Published New approach needed to save Australia's non-perennial rivers
(via sciencedaily.com) Original source An extensive review of current research incorporating geomorphology, hydrology, biogeochemistry, ecology and Indigenous knowledges identifies prevailing factors that shape water and energy flows in Australia's non-perennial rivers -- but the review also points to research deficiencies that must be addressed if these river systems are to be preserved and protected.
Published Scientist helps link climate change to Madagascar's megadrought
(via sciencedaily.com) Original source A team reveals a clear link between human-driven climate change and the years-long drought currently gripping southern Madagascar.
Published Humans can increase biodiversity, archaeological study shows
(via sciencedaily.com) Original source Through the ages, the presence of humans has increased the heterogeneity and complexity of ecosystems and has often had a positive effect on their biodiversity.
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 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 Researchers envision sci-fi worlds involving changes to atmospheric water cycle
(via sciencedaily.com) Original source Human activity is changing the way water flows between the Earth and atmosphere in complex ways and with likely long-lasting consequences that are hard to picture. Researchers enlisted water scientists from around the globe to write story-based scenarios about the possible futures humanity is facing but perhaps can't quite comprehend yet. The results are part of a creative pathway to understand atmospheric water research with an eye towards the potential economic and policy issues that may be just beyond the horizon.
