Published A new way of thinking about the economy could help protect the Amazon, and help its people thrive
(via sciencedaily.com) Original source To protect the Amazon and support the wellbeing of its people, its economy needs to shift from environmentally harmful production to a model built around the diversity of indigenous and rural communities, and standing forests.
Published Groundwater reserves in southwestern Europe more stable overall than previously thought
(via sciencedaily.com) Original source Groundwater is a vital resource, sustaining plants and ecosystems, ensuring agricultural production and serving as a core component of drinking water supplies. However, climate change and anthropogenic pressures can threaten groundwater availability, especially in southwestern Europe. This threat was evaluated by a research team using multidecadal data from more than 12,000 groundwater wells in Portugal, Spain, France, and Italy. The surprising finding: Groundwater levels are not declining everywhere as widely believed, but primarily in semi-arid regions with intensive agriculture and frequent droughts. Declines are also observed in temperate regions associated with large urban areas. The authors conclude that, with suitable management practices, groundwater can be utilized sustainably.
Published Antarctic-wide survey of plant life to aid conservation efforts
(via sciencedaily.com) Original source The first continent-wide mapping study of plant life across Antarctica reveals growth in previously uncharted areas and is set to inform conservation measures across the region. The satellite survey of mosses, lichens and algae across the continent will form a baseline for monitoring how Antarctica's vegetation responds to climate change.
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 Forecasting climate's impact on a debilitating disease
(via sciencedaily.com) Original source In Brazil, climate and other human-made environmental changes threaten decades-long efforts to fight schistosomiasis, a widespread and debilitating parasitic disease. Now, researchers have developed models that can predict how the disease risk will shift in response to environmental changes.
Published Seismic detectors measure soil moisture using traffic noise
(via sciencedaily.com) Original source Using state of the art techniques, researchers use vibrations from traffic to measure underground soil moisture.
Published New model refutes leading theory on how Earth's continents formed
(via sciencedaily.com) Original source Computational modeling shows that plate tectonics weren't necessary for early continents.
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 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 Research catalogs greenhouse gas emissions tied to energy use for interbasin water transfers
(via sciencedaily.com) Original source Much of the water in the West is transported across vast geographical areas by large infrastructure projects known as interbasin water transfers. Two of these projects in particular make up 85% of all energy-related greenhouse gas emissions associated with U.S. interbasin transfers -- one in Arizona and the other in California -- according to the new research.
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 Sustainable and reversible 3D printing method uses minimal ingredients and steps
(via sciencedaily.com) Original source A new 3D printing method developed by engineers is so simple that it uses a polymer ink and salt water solution to create solid structures. The work has the potential to make materials manufacturing more sustainable and environmentally friendly.
Published Multiple urinary metals play key role in cardiovascular disease and mortality, study finds
(via sciencedaily.com) Original source Higher levels of urinary metals such as cadmium, tungsten, uranium, cobalt, copper and zinc are linked to increased cardiovascular disease and mortality in a racially and ethnically diverse U.S. population, according to a new study.
Published Warming stops tiny organisms working together
(via sciencedaily.com) Original source Hotter conditions prevent two tiny organisms working together for mutual benefit, new research shows.
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.
