Published Study reveals urban trees suffer more from heat waves and drought than their rural counterparts
(via sciencedaily.com) Original source A recent study details how trees in New York City and Boston are more negatively impacted by heat waves and drought than trees of the same species in nearby rural forests. The finding highlights the challenges urban trees face in the context of climate change and underscores the importance of tailored urban forestry management as a tool for protecting tree species and reducing urban heat islands.
Published Protecting surf breaks mitigates climate change, helps coastal communities
(via sciencedaily.com) Original source Safeguarding places to hang ten and shoot the curl is an opportunity to simultaneously mitigate climate change, fuel tourism and help surrounding ecosystems, research has shown.
Published New study unveils 16,000 years of climate history in the tropical Andes
(via sciencedaily.com) Original source Researchers highlight the roles of carbon dioxide and ocean currents as key drivers of temperature fluctuations in the tropical Andes over a 16,000 year period.
Published Record-breaking recovery of rocks that originated in Earth's mantle could reveal secrets of planet's history
(via sciencedaily.com) Original source Scientists have recovered the first long section of rocks that originated in the Earth's mantle, the layer below the crust and the planet's largest component. The rocks will help unravel the mantle's role in the origins of life on Earth, the volcanic activity generated when it melts, and how it drives the global cycles of important elements such as carbon and hydrogen.
Published South Florida estuaries warming faster than Gulf of Mexico, global ocean, USF research shows
(via sciencedaily.com) Original source Estuaries in South Florida have experienced rapid warming over the past two decades, including a record-breaking marine heat wave in 2023, research shows. The findings paint a troubling picture for the marine life that calls Florida home. Possible causes include evaporation, water capacity and residence time (the amount of time water spends in an estuary). No single factor has been identified as dominant.
Published New report on Great Barrier Reef shows coral cover increases before onset of serious bleaching, cyclones
(via sciencedaily.com) Original source Coral cover has increased in all three regions on the Great Barrier Reef and is at regional highs in two of the three regions, according to a new report. But the results come with a note of caution.
Published The race to discover biodiversity: 11 new marine species and a new platform for rapid species description
(via sciencedaily.com) Original source A new paper describes a ground-breaking experiment that united 25 independent taxonomists from 10 countries. The initiative boasts the discovery of 11 new marine species from all over the globe, occurring at depths from 5.2 to 7081 meters. It also represents a significant step forward in accelerating the pace at which new marine species are described and published.
Published Greenland fossil discovery reveals increased risk of sea-level catastrophe
(via sciencedaily.com) Original source Seeds, twigs, and insect parts found under two miles of ice confirm Greenland's ice sheet melted in the recent past, the first direct evidence that the center -- not just the edges -- of the two-mile-deep ice melted away in the recent geological past. The new research indicates that the giant ice sheet is more fragile than scientists had realized until the last few years -- and reveals increased risk of sea-level catastrophe in a warmer future.
Published How the rising earth in Antarctica will impact future sea level rise
(via sciencedaily.com) Original source The rising earth beneath the Antarctic Ice Sheet will likely become a major factor in future sea level rise, a new study suggests.
Published Link between global warming and rising sea levels
(via sciencedaily.com) Original source A new study suggests that Earth's natural forces could substantially reduce Antarctica's impact on rising sea levels, but only if carbon emissions are swiftly reduced in the coming decades. By the same token, if emissions continue on the current trajectory, Antarctic ice loss could lead to more future sea level rise than previously thought.
Published Sea level changes shaped early life on Earth, fossil study reveals
(via sciencedaily.com) Original source Shifts in the Earth's continental plates that drove long-term changes in sea level set the stage for the evolution of the earliest animals on Earth, a study suggests.
Published Combined effects of plastic pollution and seawater flooding amplify threats to coastal plant species
(via sciencedaily.com) Original source A new study highlights how a combination of environmental stressors -- namely plastic pollution and seawater flooding -- can increase the threats faced by plants in some of the planet's critical ecosystems. It showed that both stressors had some effects on the species tested, but being exposed to both microplastics and flooding together -- a threat likely to increase as a result of climate change and plastic use -- had a more pronounced impact on their resource allocation.
Published Retreat of tropical glaciers foreshadows changing climate's effect on the global ice
(via sciencedaily.com) Original source As they are in many places around the globe, glaciers perched high in the Andes Mountains are shrinking. Now, researchers have uncovered evidence that the high-altitude tropical ice fields are likely smaller than they've been at any time since the last ice age ended 11,700 years ago.
Published Climate change may lead to shifts in vital Pacific Arctic fisheries
(via sciencedaily.com) Original source Commercially important marine fish and invertebrate species will likely shift northwards under a warmer climate, according to new research.
Published 3D models provide unprecedented look at corals' response to bleaching events
(via sciencedaily.com) Original source Marine biologists are providing a glimpse into coral 'bleaching' responses to stress, using imaging technology to pinpoint coral survival rates following multiple bleaching events off the island of Maui. Using a time series of coral reef 3D models from Maui, the researchers tracked the bleaching response of 1,832 coral colonies from 2014 to 2021. The seven-year data set provided detailed imagery of the reefs year-by-year, allowing the team to identify patterns of coral growth and survivorship through sequential bleaching events that occurred in 2015 and 2019.
Published Underwater mapping reveals new insights into melting of Antarctica's ice shelves
(via sciencedaily.com) Original source Clues to future sea level rise have been revealed by the first detailed maps of the underside of a floating ice shelf in Antarctica. An international research team deployed an unmanned submersible beneath the Dotson Ice Shelf in West Antarctica.
Published Barriers designed to prevent saltwater intrusion may worsen inland flooding
(via sciencedaily.com) Original source Building protection barriers without accounting for potential inland flooding risks from groundwater can eventually worsen the very issues they aim to solve.
Published Climate change means that tropical cyclones in Southeast Asia are developing faster, lasting longer
(via sciencedaily.com) Original source A study reveals that tropical cyclones in Southeast Asia are now forming closer to coastlines, intensifying more rapidly, and lingering longer over land.
Published What's the weather like in the deep sea?
(via sciencedaily.com) Original source A new study has revealed how even the deepest seafloors are affected by the daily back-and-forth of the tides, and the change of the seasons, and that currents at the bottom of the ocean are far more complicated than previously thought. These findings are helping us understand the deep-sea pathways of nutrients that support important deep-sea ecosystems, assess where microplastics and other pollutants accumulate in the ocean, and reconstruct past climate change.
Published Strong El Nino makes European winters easier to forecast
(via sciencedaily.com) Original source Forecasting European winter weather patterns months in advance is made simpler during years of strong El Ni o or La Ni a events in the tropical Pacific Ocean, a new study has found.
