Published A century of reforestation helped keep the eastern US cool
(via sciencedaily.com) Original source Widespread 20th-century reforestation in the eastern United States helped counter rising temperatures due to climate change, according to new research. The authors highlight the potential of forests as regional climate adaptation tools, which are needed along with a decrease in carbon emissions.
Published New study points to more climate extremes
(via sciencedaily.com) Original source A new study has found similarities between long-term climatic changes in South Australia and temperate agricultural areas in Argentina -- highlighting similarities across these Southern Hemisphere countries. As temperature records tumble, and the threat of bushfires and dry conditions looms large, researchers renew the urgency of calls to make more concerted efforts to prepare for climate extremes in South Australia.
Published In a warming world, climate scientists consider category 6 hurricanes
(via sciencedaily.com) Original source For more than 50 years, the National Hurricane Center has used the Saffir-Simpson Windscale to communicate the risk of property damage; it labels a hurricane on a scale from Category 1 (wind speeds between 74 -- 95 mph) to Category 5 (wind speeds of 158 mph or greater). But as increasing ocean temperatures contribute to ever more intense and destructive hurricanes, climate scientists wondered whether the open-ended Category 5 is sufficient to communicate the risk of hurricane damage in a warming climate.
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 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 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 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 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.
Published Thermal vision shows endangered numbats feel the heat of warming climate
(via sciencedaily.com) Original source Research using thermal imaging of numbats in Western Australia has found that during hot weather the endangered animals are limited to as little as ten minutes of activity in the sun before they overheat to a body temperature of greater than 40 C.
Published Record heat in 2023 worsened global droughts, floods and wildfires
(via sciencedaily.com) Original source Record heat across the world profoundly impacted the global water cycle in 2023, contributing to severe storms, floods, megadroughts and bushfires, new research shows.
