Published Sister cities can help communities better navigate the climate crisis
(via sciencedaily.com) Original source Anthropologists suggest in a new study that establishing networks of 'sister cities' dedicated to addressing the impact of natural disasters can mitigate the devastation wrought by climate change.
Published Climate change amplifies severity of combined wind-rain extremes over the UK and Ireland
(via sciencedaily.com) Original source Climate change will cause an increase in extreme winter storms combining strong winds and heavy rainfall over the UK and Ireland, new research has shown.
Published Wildfires in wet African forests have doubled in recent decades
(via sciencedaily.com) Original source Climate change and human activities like deforestation are causing more fires in central and west Africa's wet, tropical forests, according to the first-ever comprehensive survey there. The fires have long been overlooked.
Published A 'cosmic glitch' in gravity
(via sciencedaily.com) Original source Researchers have discovered a potential 'cosmic glitch' in the universe's gravity, explaining its strange behavior on a cosmic scale.
Published Webb captures top of iconic horsehead nebula in unprecedented detail
(via sciencedaily.com) Original source NASA's James Webb Space Telescope has captured the sharpest infrared images to date of a zoomed-in portion of one of the most distinctive objects in our skies, the Horsehead Nebula. These observations show the top of the 'horse's mane' or edge of this iconic nebula in a whole new light, capturing the region's complexity with unprecedented spatial resolution.
Published Astronomers' simulations support dark matter theory
(via sciencedaily.com) Original source Computer simulations by astronomers support the idea that dark matter -- matter that no one has yet directly detected but which many physicists think must be there to explain several aspects of the observable universe -- exists, according to the researchers.
Published Gemini south reveals origin of unexpected differences in giant binary stars
(via sciencedaily.com) Original source Astronomers have confirmed that differences in binary stars' composition can originate from chemical variations in the cloud of stellar material from which they formed. The results help explain why stars born from the same molecular cloud can possess different chemical composition and host different planetary systems, as well as pose challenges to current stellar and planet formation models.
Published Details of hurricane Ian's aftermath captured with new remote sensing method
(via sciencedaily.com) Original source Using aerial imagery data and LiDAR, a study remotely identified the hardest-hit areas of Southwest Florida's Estero Island in the aftermath of Hurricane Ian. Researchers estimated the extent of structural damage and compared pre- and post-storm beach structural changes. They identified 2,427 structures that were impacted. The value of the heavily damaged structures was estimated at more than $200 million. The study has applied an advanced multi-faceted approach that links damage assessment to post-storm change in the structure of barrier islands.
Published Scientists capture X-rays from upward positive lightning
(via sciencedaily.com) Original source Researchers have for the first time recorded X-rays being produced at the beginning of upward positive lightning flashes; an observation that gives important insight into the origins of this rare -- and particularly dangerous -- form of lightning.
Published New offshore wind turbines can take away energy from existing ones
(via sciencedaily.com) Original source Interactions between wind turbines could reduce power output by 30% in proposed offshore wind farm areas along the East Coast, new research has found. In all, the farms could still meet 60% of the electricity demand of New England.
Published Warming Arctic reduces dust levels in parts of the planet
(via sciencedaily.com) Original source Dust can have a huge impact on local air quality, food security, energy supply and public health. Previous studies have found that dust levels are decreasing across India, particularly northern India, the Persian Gulf Coast and much of the Middle East, but the reason has remained unclear. Researchers found that the decrease in dust can be attributed to the Arctic warming much faster than the rest of the planet, a phenomenon known as Arctic amplification. This process destabilizes the jet stream and changes storm tracks and wind patterns over the major sources of dust in West and South Asia.
Published Hurricanes jeopardize carbon-storing New England forests
(via sciencedaily.com) Original source Many American companies are relying on carbon offsets to reduce their carbon footprint, especially those who have pledged to achieve 'net-zero emissions.' Sequestering carbon in forests is an example of a nature-based solution that is being used to address climate change, but a new study suggests that hurricanes could pose a risk. The results show that a single hurricane may wipe out 5% to 10% of total above-ground forest carbon, through tree damage, in New England.
Published Shoreline model predicts long-term future of storm protection and sea-level rise
(via sciencedaily.com) Original source Researchers have created a coastal evolution model to analyze how coastal management activities on barrier islands, meant to adapt to sea-level rise, can disrupt natural processes that are keeping the barrier islands above water. Replenishing beaches and clearing over-washed roads may not be the best long term strategy.
Published Marginalized communities developed 'disaster subculture' when living through extreme climate events
(via sciencedaily.com) Original source An assistant professor conducted a study in which he lived among one of the poorest, most marginalized communities in Seoul, South Korea. In the ethnographic study, he asked residents how they dealt with extreme heat. He found they tended to accept the conditions, stating there was not much that could be done. That shows people accepted extreme climate events, despite evidence showing this should not be normal, which bodes the argument social work as a field has much to do to help address climate emergencies.
Published 'Sunny day flooding' increases fecal contamination of coastal waters
(via sciencedaily.com) Original source A new study finds that 'sunny day flooding,' which occurs during high tides, increases the levels of fecal bacteria in coastal waters. While the elevated bacteria levels in the coastal waters tend to dissipate quickly, the findings suggest policymakers and public health officials should be aware of potential risks associated with tidal flooding.
Published Toward unification of turbulence framework -- weak-to-strong transition discovered in turbulence
(via sciencedaily.com) Original source Astrophysicists have made a significant step toward solving the last puzzle in magnetohydrodynamic turbulence theory by observing the weak to strong transition in the space plasma turbulence surrounding Earth with newly developed multi-spacecraft analysis methods.
Published Everest mountaineer's letters digitized
(via sciencedaily.com) Original source Letters written by the famous mountaineer George Mallory have been made available to a global audience for the first time, in the centenary year of his fatal attempt to scale Everest.
Published Giant galactic explosion exposes galaxy pollution in action
(via sciencedaily.com) Original source Astronomers have produced the first high-resolution map of a massive explosion in a nearby galaxy, providing important clues on how the space between galaxies is polluted with chemical elements.
Published AI weather forecasts captured Ciaran's destructive path
(via sciencedaily.com) Original source The study highlights the rapid progress and transformative potential of AI in weather prediction.
Published Weather prediction models can also forecast satellite displacements
(via sciencedaily.com) Original source Researchers have found that modern weather models can accurately predict the energy that Earth emits and reflects into space, which directly affects the movements of low Earth-orbiting (LEO) satellites. By leveraging these models, the researchers gained insights into how LEO satellites respond to weather events below, such as tropical cyclones with tall and reflective clouds.
