Published Understanding climate warming impacts on carbon release from the tundra



The warming climate shifts the dynamics of tundra environments and makes them release trapped carbon, according to a new study published in Nature. These changes could transform tundras from carbon sinks into a carbon source, exacerbating the effects of climate change.
Published Substantial global cost of climate inaction



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 Exposure to air pollution during the first two years of life is associated with worse attention capacity in children



A growing body of research shows that exposure to air pollution, especially during pregnancy and childhood, may have a negative impact on brain development. Now a study has found that exposure to nitrogen dioxide (NO2) during the first two years of life is associated with poorer attention capacity in children aged 4 to 8, especially in boys. NO2 is a pollutant that comes mainly from traffic emissions.
Published How soil microbes survive in harsh desert environments



Prolonged droughts followed by sudden bursts of rainfall -- how do desert soil bacteria manage to survive such harsh conditions? This long-debated question has now been answered by microbiologists. The study reveals that desert soil bacteria are highly adapted to survive the rapid environmental changes experienced with each rainfall event.
Published Unique field study shows how climate change affects fire-impacted forests



During the unusually dry year of 2018, Sweden was hit by numerous forest fires. A research team has investigated how climate change affects recently burnt boreal forests and their ability to absorb carbon dioxide.
Published Paradox of extreme cold events in a warming world



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



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



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



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



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



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



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



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



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



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



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



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 Most countries struggle to meet climate pledges from 2009



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



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



Manufacturing nations in the Global North are stockpiling energy and emission problems by outsourcing energy-intensive industrial processes to countries in the Global South.
