Published A fifth higher: Tropical cyclones substantially raise the Social Cost of Carbon
(via sciencedaily.com) Original source Extreme events like tropical cyclones have immediate impacts, but also long-term implications for societies. A new study now finds: Accounting for the long-term impacts of these storms raises the global Social Cost of Carbon by more than 20 percent, compared to the estimates currently used for policy evaluations. This increase is mainly driven by the projected rise of tropical-cyclone damages to the major economies of India, USA, China, Taiwan, and Japan under global warming.
Published AI finds formula on how to predict monster waves
(via sciencedaily.com) Original source Using 700 years' worth of wave data from more than a billion waves, scientists have used artificial intelligence to find a formula for how to predict the occurrence of these maritime monsters. Long considered myth, freakishly large rogue waves are very real and can split apart ships and even damage oil rigs.
Published Deep dive on sea level rise: New modelling gives better predictions on Antarctic ice sheet melt
(via sciencedaily.com) Original source Using historical records from around Australia, an international team of researchers have put forward the most accurate prediction to date of past Antarctic ice sheet melt, providing a more realistic forecast of future sea level rise. The Antarctic ice sheet is the largest block of ice on earth, containing over 30 million cubic kilometers of water. Hence, its melting could have a devasting impact on future sea levels. To find out just how big that impact might be, the research team turned to the past.
Published Idai vs. Impalas: New study shows in real-time what helps mammals survive a natural disaster
(via sciencedaily.com) Original source After a massive cyclone transformed the ecosystem of Gorongosa National Park, researchers studied the immediate and knock-on impacts to garner lessons for wildlife managers around the world.
Published Temperature variability reduces nesting success
(via sciencedaily.com) Original source Many songbirds are nesting earlier in spring because of warmer temperatures brought about by climate change. But the shift brings another danger that is especially deadly for nestlings: greater exposure to temperature variability in the form of cold snaps and heat waves.
Published Not so silver lining: Microplastics found in clouds could affect the weather
(via sciencedaily.com) Original source From the depths of the seas to snow on mountains and even the air above cities, microplastics are turning up increasingly often. Now, researchers have analyzed microplastics in clouds above mountains. They suggest that these tiny particles could play a role in cloud formation and, in turn, affect weather.
Published New study reveals surprising insights into feeding habits of carnivorous dinosaurs in North America
(via sciencedaily.com) Original source New research sheds light on the dining habits of ancient carnivorous dinosaurs from Jurassic rocks of the USA. A recent study explores the bite marks left on the ancient bones of the giant long-necked sauropod dinosaurs like Diplodocus and Brontosaurus by carnivorous theropod dinosaurs.
Published How climate change could be affecting your brain
(via sciencedaily.com) Original source A new element of the catastrophic impacts of climate change is emerging -- how global warming is impacting the human brain.
Published Wildfire, drought cause $11.2 billion in damage to private timberland in three Pacific states, study finds
(via sciencedaily.com) Original source Wildfires and drought have led to $11.2 billion in damages to privately held timberland in California, Oregon and Washington over the past two decades, a new Oregon State University study found.
Published Designing cities for 21st-century weather
(via sciencedaily.com) Original source Researchers have investigated how changes in urban land and population will affect future populations' exposures to weather extremes under climate conditions at the end of the 21st century. They used a data-driven model to predict how urban areas across the country will grow by 2100, and found that how a city is laid out or organized spatially has the potential to reduce population exposures to future weather extremes.
Published New cooling ceramic can enhance energy efficiency for the construction sector and help combat global warming
(via sciencedaily.com) Original source Researchers have made a significant breakthrough in developing a passive radiative cooling (PRC) material. The material, known as cooling ceramic, has achieved high-performance optical properties for energy-free and refrigerant-free cooling generation. Its cost-effectiveness, durability and versatility make it highly suitable for commercialization in numerous applications, particularly in building construction.
Published Lightning identified as the leading cause of wildfires in boreal forests, threatening carbon storage
(via sciencedaily.com) Original source Most wildfires in boreal forests, such as those in Canada, are caused by lightning strikes, according to a study aimed at attributing fire ignition sources globally.
Published Crust-forming algae are displacing corals in tropical waters worldwide
(via sciencedaily.com) Original source Over the past few decades, algae have been slowly edging corals out of their native reefs across the globe by blocking sunlight, wearing the corals down physically, and producing harmful chemicals. But in recent years, a new type of algal threat has surfaced in tropical regions like the Caribbean -- one that spreads quickly and forms a crust on top of coral and sponges, suffocating the organisms underneath and preventing them from regrowing. Marine biologists report that peyssonnelioid alga crusts, or PACs, are expanding quickly across reefs worldwide, killing off corals and transforming entire ecosystems.
Published The kids aren't alright: Saplings reveal how changing climate may undermine forests
(via sciencedaily.com) Original source Researchers studied how young trees respond to a hotter, drier climate. Their findings can help shape forest management policy and our understanding of how landscapes will change.
Published Damaging thunderstorm winds increasing in central U.S.
(via sciencedaily.com) Original source Destructive winds that flow out of thunderstorms in the central United States are becoming far more widespread with warming temperatures, according to new research. A new study shows that the central U.S. experienced a fivefold increase in the geographic area affected by damaging thunderstorm straight line winds in the past 40 years.
Published Giant dinosaur carcasses might have been important food sources for Jurassic predators
(via sciencedaily.com) Original source Carnivorous dinosaurs might have evolved to take advantage of giant carcasses, according to a new study.
Published Ocean warming is accelerating, and hotspots reveal which areas are absorbing the most heat
(via sciencedaily.com) Original source A new study reveals increasing warming rates in the world's oceans in recent decades and the locations with the greatest heat uptake.
Published The importance of the Earth's atmosphere in creating the large storms that affect satellite communications
(via sciencedaily.com) Original source Large geomagnetic storms disrupt radio signals and GPS. Now, researchers have identified the previous underestimated role of the ionosphere, a region of Earth's upper atmosphere that contains a high concentration of ions and free electrons, in determining how such storms develop. Understanding the interactions that cause large geomagnetic storms is important because they can disrupt radio signals and GPS. Their findings may help predict storms with the greatest potential consequences.
Published Scientists find two ways that hurricanes rapidly intensify
(via sciencedaily.com) Original source Scientists at NCAR have identified two entirely different modes of hurricane rapid intensification. The findings may lead to better understanding and prediction of these dangerous events.
Published Rider on the storm: Shearwater seabird catches an 11 hour ride over 1,000 miles in a typhoon
(via sciencedaily.com) Original source New research suggests that increasingly severe weather driven by climate change may push oceangoing seabirds to their limits.
