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 Scientists pin down the origins of the moon's tenuous atmosphere
(via sciencedaily.com) Original source Scientists say they have identified the main process that formed the moon's atmosphere and continues to sustain it today. The team reports that the lunar atmosphere is primarily a product of 'impact vaporization.'
Published Born to modulate: Researchers reveal origins of climate-controlling particles
(via sciencedaily.com) Original source Aerosol particles imbue climate models with uncertainty. New work reveals where in the world and under what conditions new particles are born.
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 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 Key to rapid planet formation
(via sciencedaily.com) Original source Researchers have developed a new model to explain the formation of giant planets such as Jupiter, which furnishes deeper insights into the processes of planet formation and could expand our understanding of planetary systems.
Published Tipping risks from overshooting 1.5 °C can be minimized if warming is swiftly reversed
(via sciencedaily.com) Original source Current climate policies imply a high risk for tipping of critical Earth system elements, even if temperatures return to below 1.5 C of global warming after a period of overshoot. A new study indicates that this risk can be minimized if the warming is swiftly reversed. That is why reducing emissions in the current decade is crucial for the stability of the Earth systems functions, researchers write. They analyzed the tipping risks for four interconnected core climate tipping elements: the Greenland Ice Sheet, the West Antarctic Ice Sheet, the Atlantic Meridional Overturning Circulation (AMOC), and the Amazon Rainforest.
Published Towards smart cities: Predicting soil liquefaction risk using artificial intelligence
(via sciencedaily.com) Original source Soil liquefaction that results in infrastructure damage has long been a point of contention for urban planners and engineers. Accurately predicting the soil liquefaction risk of a region could help overcome this challenge. Accordingly, researchers applied artificial intelligence to generate soil liquefaction risk maps, superseding already published risk maps.
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 Scientists devise method to secure Earth's biodiversity on the moon
(via sciencedaily.com) Original source New research led proposes a plan to safeguard Earth's imperiled biodiversity by cryogenically preserving biological material on the moon. The moon's permanently shadowed craters are cold enough for cryogenic preservation without the need for electricity or liquid nitrogen.
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 Monarch butterflies need help, and a little bit of milkweed goes a long way
(via sciencedaily.com) Original source Researchers and community scientists monitored urban milkweed plants for butterfly eggs to learn what makes these city gardens more hospitable to monarchs. They found that even tiny city gardens attracted monarchs and became a home to caterpillars.
Published The rotation of a nearby star stuns astronomers
(via sciencedaily.com) Original source Astronomers have found that the rotational profile of a nearby star, V889 Herculis, differs considerably from that of the Sun. The observation provides insights into the fundamental stellar astrophysics and helps us understand the activity of the Sun, its spot structures and eruptions.
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.
Published North Sea oil and gas extraction spikes pollution by 10,000 percent, study finds
(via sciencedaily.com) Original source North Sea oil and gas extraction can cause pollution to spike by more than 10,000 percent within half a kilometer around off-shore sites, a study has found. The research has uncovered the true impact on Britain's seabed life -- with the number of species plummeting nearly 30 percent near platforms.
Published The corona is weirdly hot: Parker Solar Probe rules out one explanation
(via sciencedaily.com) Original source By diving into the sun's corona, NASA's Parker Solar Probe has ruled out S-shaped bends in the sun's magnetic field as a cause of the corona's searing temperatures.
Published NASA data shows July 22, 2024 was Earth's hottest day on record
(via sciencedaily.com) Original source July 22, 2024, was the hottest day on record, according to a NASA analysis of global daily temperature data. July 21 and 23 of this year also exceeded the previous daily record, set in July 2023. These record-breaking temperatures are part of a long-term warming trend driven by human activities, primarily the emission of greenhouse gases.
Published Countries need to co-operate on migration as climate crisis worsens
(via sciencedaily.com) Original source Humanity must rethink migration as the climate crisis drives rapid global changes, researchers say.
