Published Researchers find oldest undisputed evidence of Earth's magnetic field
(via sciencedaily.com) Original source A new study has recovered a 3.7-billion-year-old record of Earth's magnetic field, and found that it appears remarkably similar to the field surrounding Earth today.
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 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 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.
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 Marine plankton behavior could predict future marine extinctions
(via sciencedaily.com) Original source Marine communities migrated to Antarctica during the Earth's warmest period in 66 million years long before a mass-extinction event.
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.
Published Yellowstone Lake ice cover unchanged despite warming climate
(via sciencedaily.com) Original source While most lakes around the world are experiencing shorter durations of ice cover, the length of time that Yellowstone Lake is covered by ice each year has not changed in the past century, possibly due to increased snowfall.
Published Food security in developed countries shows resilience to climate change
(via sciencedaily.com) Original source A study has found that market forces have provided good food price stability over the past half century, despite extreme weather conditions.
Published Scientist helps link climate change to Madagascar's megadrought
(via sciencedaily.com) Original source A team reveals a clear link between human-driven climate change and the years-long drought currently gripping southern Madagascar.
Published Research examines tweets during Hurricane María to analyze social media use during disasters
(via sciencedaily.com) Original source Understanding how social media is used during a disaster can help with disaster preparedness and recovery for future events.
Published How climate change will impact food production and financial institutions
(via sciencedaily.com) Original source Researchers have developed a new method to predict the financial impacts climate change will have on agriculture, which can help support food security and financial stability for countries increasingly prone to climate catastrophes.
Published Climate change threatens Antarctic meteorites
(via sciencedaily.com) Original source Antarctica harbors a large concentration of meteorites imbuing the icy continent with an unparalleled wealth of information on our solar system. However, these precious meteorites are rapidly disappearing from the ice sheet surface due to global warming, according to a new study.
