Published Source rocks of the first real continents
(via sciencedaily.com) Original source Geoscientists have uncovered a missing link in the enigmatic story of how the continents developed- - a revised origin story that doesn't require the start of plate tectonics or any external factor to explain their formation. Instead, the findings rely solely on internal geological forces that occurred within oceanic plateaus that formed during the first few hundred million years of Earth's history.
Published Death toll shows extreme air pollution events a growing urban threat
(via sciencedaily.com) Original source New research has estimated that 1454 avoidable deaths (one person every five days) occurred in Australian capital cities in the past 20 years because of fine particle air pollution from extreme events such as bushfires and dust storms, wood-heater smoke or industrial accidents.
Published Unprecedented ocean heating shows risks of a world 3°C warmer
(via sciencedaily.com) Original source New research examines the causes of the record-breaking ocean temperatures witnessed in 2023.
Published Fungal-rich soil may improve green roofs
(via sciencedaily.com) Original source Green roofs have become increasingly popular thanks to their benefits related to climate adaptation, mitigation, and urban biodiversity management. But, in the U.S., green roofs are typically planted with non-native plants in sterile soils, and their effectiveness declines over time. A new study finds that managing green roof soil microbes boosts healthy urban soil development, which is a methodology that could be applied to support climate resilience in cities.
Published Compounding risks of atmospheric river storms
(via sciencedaily.com) Original source When storms hit back-to-back, the flooding -- and economic damages -- are even worse than expected.
Published Unexpected biodiversity on the ocean floor
(via sciencedaily.com) Original source Hydrothermal vents and manganese nodule fields in the deep oceans contain more biodiversity than expected.
Published Diverse forests are best at standing up to storms
(via sciencedaily.com) Original source European forests with a greater diversity of tree species are more resilient to storms, according to new research.
Published Self-powered movable seawall for tsunami protection and emergency power generation
(via sciencedaily.com) Original source A movable seawall system, capable of generating sufficient electricity to raise gates and protect ports against tsunamis, has been proposed by researchers. The system has been found feasible in areas prone to Nankai Trough earthquake tsunamis. Additionally, it can generate surplus energy to supply emergency power to ports during power outages that commonly occur in natural disasters. This innovative system integrates disaster prevention with the use of renewable energy.
Published Global warming has a bigger effect on compact, fast-moving typhoons
(via sciencedaily.com) Original source A group has found that larger, slow-moving typhoons are more likely to be resilient to the effects of global warming. However, more compact, fast-moving storms are more likely to be sensitive. These findings suggest an improved method for projecting the strength of typhoons under global warming conditions.
Published Paper provides a clearer picture of severe hydro hazards
(via sciencedaily.com) Original source A new study now provides a global examination of drought-pluvial volatility -- or the tendency to shift from one weather extreme to another.
Published New tool predicts flood risk from hurricanes in a warming climate
(via sciencedaily.com) Original source A new method predicts how much flooding a coastal community is likely to experience as hurricanes evolve due to climate change. Using New York as a test case, the model predicts Hurricane Sandy-level flooding will occur roughly every 30 years by 2099.
Published Records of cometary dust hitting the asteroid Ryugu
(via sciencedaily.com) Original source The Hayabusa2 mission that collected samples from the asteroid Ryugu has provided a treasure trove of insights into our solar system. After analyzing samples further, a team of researchers have unearthed evidence that cometary organic matter was transported from space to the near-Earth region.
Published Links discovered between weather patterns and power outages could help UK protect itself from disruptive weather
(via sciencedaily.com) Original source The behavior of specific weather patterns and their impact on power faults could be used to develop a weather pattern - conditioned fault forecasting system for power system operators.
Published Planetary Commons: Fostering global cooperation to safeguard critical Earth system functions
(via sciencedaily.com) Original source Tipping elements of the Earth system should be considered global commons, researchers argue. Global commons cannot -- as they currently do -- only include the parts of the planet outside of national borders, like the high seas or Antarctica. They must also include all the environmental systems that regulate the functioning and state of the planet, namely all systems on Earth we all depend on, irrespective on where in the world we live. This calls for a new level of transnational cooperation, leading experts in legal, social and Earth system sciences say. To limit risks for human societies and secure critical Earth system functions they propose a new framework of planetary commons to guide governance of the planet.
Published Wobbling particles in the sky
(via sciencedaily.com) Original source Tiny particles such as ice crystals or ash particles tend to oscillate as they settle through the atmosphere. In their experiments, the scientists were able to track non-spherical particles of size smaller than 1 millimeter with unprecedented accuracy. Their observations gave rise to a model which can help to refine prediction on air pollutants or weather forecasts.
Published Climate change linked to spread of diarrheal illness
(via sciencedaily.com) Original source Temperature, day length and humidity have been found to be linked to the increased spread of a diarrheal illness a new study reveals. The findings could help predict further outbreaks of the illness, potentially leading to better preparedness within health services.
Published Butterflies could lose spots as climate warms
(via sciencedaily.com) Original source Female meadow brown butterflies have fewer spots if they develop in warmer weather -- so climate change could make them less spotty, new research shows.
Published Key factors in human-made earthquakes
(via sciencedaily.com) Original source Researchers report that the roughness of pre-existing faults and associated stress heterogeneity in geological reservoirs play a key role for causing human-made earthquakes, so-called runaway events. The study combines novel fluid injection experiments under acoustic monitoring performed in GFZ's geomechanical laboratory with numerical modelling results.
Published Climate change isn't producing expected increase in atmospheric moisture over dry regions
(via sciencedaily.com) Original source The warming climate has not lead to an expected increase in atmospheric moisture over arid and semi-arid regions of the world. The finding, which has surprised scientists, indicates that some regions may be even more vulnerable to future wildfires and extreme heat than projected.
Published Pain-based weather forecasts could influence actions
(via sciencedaily.com) Original source For individuals who experience chronic pain, weather can be a significant factor in their day-to-day plans. In a recent study, about 70 percent of respondents said they would alter their behavior based on weather-based pain forecasts.
