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 Coral reef microbes point to new way to assess ecosystem health
(via sciencedaily.com) Original source A new study shows that ocean acidification is changing the mix of microbes in coral reef systems, which can be used to assess ecosystem health.
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 Researchers shine light on rapid changes in Arctic and boreal ecosystems
(via sciencedaily.com) Original source Arctic and boreal latitudes are warming faster than any other region on Earth.
Published Trash to treasure -- researchers turn metal waste into catalyst for hydrogen
(via sciencedaily.com) Original source Scientists have found a way to transform metal waste into a highly efficient catalyst to make hydrogen from water, a discovery that could make hydrogen production more sustainable.
Published CO2 worsens wildfires by helping plants grow
(via sciencedaily.com) Original source By fueling the growth of plants that become kindling, carbon dioxide is driving an increase in the severity and frequency of wildfires, according to a new study.
Published Study reveals how humanity could unite to address global challenges
(via sciencedaily.com) Original source New research has found that perceptions of globally shared life experiences and globally shared biology can strengthen psychological bonding with humanity at large, which can motivate prosocial action on a global scale and help to tackle global problems.
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 New tagging method provides bioadhesive interface for marine sensors on diverse, soft, and fragile species
(via sciencedaily.com) Original source Tagging marine animals with sensors to track their movements and ocean conditions can provide important environmental and behavioral information. Existing techniques to attach sensors currently largely rely on invasive physical anchors, suction cups, and rigid glues. While these techniques can be effective for tracking marine animals with hard exoskeletons and large animals such as sharks, individuals can incur physiological and metabolic stress during the tagging process, which can affect the quality of data collection. A newly developed soft hydrogel-based bioadhesive interface for marine sensors, referred to as BIMS, holds promise as an effective, rapid, robust, and non-invasive method to tag and track all sorts of marine species, including soft and fragile species. The BIMS tagging, which is also simple and versatile, can help researchers better understand animal behavior while also capturing oceanographic data critical for helping to better understand some impacts of climate change and for resource management.
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 Florida Wildlife Corridor eases worst impacts of climate change
(via sciencedaily.com) Original source Florida is projected to lose 3.5 million acres of land to development by 2070. A new study highlights how Florida can buffer itself against both climate change and population pressures by conserving the remaining 8 million acres of 'opportunity areas' within the Florida Wildlife Corridor (FLWC), the only designated statewide corridor in the U.S. Interactions between the FLWC and climate change had not been previously examined until now. Findings show substantial climate resilience benefits from the corridor, yielding a much higher return on investment than originally thought. About 90 percent of Floridians live within 20 miles of the corridor.
Published Seed ferns: Plants experimented with complex leaf vein networks 201 million years ago
(via sciencedaily.com) Original source According to a research team led by palaeontologists, the net-like leaf veining typical for today's flowering plants developed much earlier than previously thought, but died out again several times. Using new methods, the fossilized plant Furcula granulifer was identified as such an early forerunner. The leaves of this seed fern species already exhibited the net-like veining in the late Triassic (around 201 million years ago).
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 Researchers can help shipowners achieve ambitious climate targets
(via sciencedaily.com) Original source International shipping does not want to be a climate bad guy and is aiming to be emission-free by 2050. A new tool can help shipowners who are searching for green solutions.
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 Microplastics make their way from the gut to other organs
(via sciencedaily.com) Original source Researchers have found that microplastics -- are having a significant impact on our digestive pathways, making their way from the gut and into the tissues of the kidney, liver and brain.
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 Digging up new species of Australia and New Guinea's giant fossil kangaroos
(via sciencedaily.com) Original source Palaeontologists have described three unusual new species of giant fossil kangaroo from Australia and New Guinea, finding them more diverse in shape, range and hopping method than previously thought. The three new species are of the extinct genus Protemnodon, which lived from around 5 million to 40,000 years ago -- with one about double the size of the largest red kangaroo living today.
