Published Researchers advance detection of gravitational waves to study collisions of neutron stars and black holes
(via sciencedaily.com)
Original source 
Researchers co-led a study that will improve the detection of gravitational waves--ripples in space and time.
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 Eruption of mega-magnetic star lights up nearby galaxy
(via sciencedaily.com)
Original source 
While ESA's satellite INTEGRAL was observing the sky, it spotted a burst of gamma-rays -- high-energy photons -- coming from the nearby galaxy M82. Only a few hours later, ESA's XMM-Newton X-ray space telescope searched for an afterglow from the explosion but found none. An international team realized that the burst must have been an extra-galactic flare from a magnetar, a young neutron star with an exceptionally strong magnetic field.
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 AI and physics combine to reveal the 3D structure of a flare erupting around a black hole
(via sciencedaily.com)
Original source 
Based on radio telescope data and models of black hole physics, a team has used neural networks to reconstruct a 3D image that shows how explosive flare-ups in the disk of gas around our supermassive black hole might look.
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.
Published Climate change will increase value of residential rooftop solar panels across US, study shows
(via sciencedaily.com)
Original source 
Climate change will increase the future value of residential rooftop solar panels across the United States by up to 19% by the end of the century, according to a new study.
Published Ice age climate analysis reduces worst-case warming expected from rising CO2
(via sciencedaily.com)
Original source 
A detailed reconstruction of climate during the most recent ice age, when a large swath of North America was covered in ice, provides information on the relationship between CO2 and global temperature. Results show that while most future warming estimates remain unchanged, the absolute worst-case scenario is unlikely.
Published East coast mussel shells are becoming more porous in warming waters
(via sciencedaily.com)
Original source 
Researchers have found that over the last 120 years, the porosity -- or small-scale holes -- in mussel shells along the East Coast of the United States has increased, potentially due to warming waters. The study analyzed modern mussel shells in comparison to specimens in the Museum's historic collection.
Published 38 trillion dollars in damages each year: World economy already committed to income reduction of 19 % due to climate change
(via sciencedaily.com)
Original source 
Even if CO2 emissions were to be drastically cut down starting today, the world economy is already committed to an income reduction of 19% until 2050 due to climate change, a new study finds. These damages are six times larger than the mitigation costs needed to limit global warming to two degrees. Based on empirical data from more than 1,600 regions worldwide over the past 40 years, scientists assessed future impacts of changing climatic conditions on economic growth and their persistence.
Published Paradox of extreme cold events in a warming world
(via sciencedaily.com)
Original source 
The Warm Arctic-Cold Continent (WACC) phenomenon is the puzzling combination of Arctic warming and extreme coldness in specific mid-latitude regions. However, the progression of WACC events remains unclear amidst global warming. Scientists have now predicted a sharp decline in the WACC phenomenon post-2030s, affecting extreme weather events. These findings offer critical insights for communities, scientists, and policymakers to refine climate models and strategies and battle climate change.
Published CO2 worsens wildfires by helping plants grow
(via sciencedaily.com)
Original source 
By fueling the growth of plants that become kindling, carbon dioxide is driving an increase in the severity and frequency of wildfires, according to a new study.
