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.
Published 'Carbon vault' peat suffers greatly from drought
(via sciencedaily.com) Original source Peatlands are affected more by drought than expected. This is concerning, as these ecosystems are an important ally in the fight against climate change. Following long periods of drought, peat is able to absorb little to no extra carbon (CO2). Increasing biodiversity also does little to make peat more drought-resilient.
Published Global study of extreme drought impacts on grasslands and shrublands
(via sciencedaily.com) Original source A global study shows that the effects of extreme drought -- which is expected to increase in frequency with climate change -- has been greatly underestimated for grasslands and shrublands. The findings quantify the impact of extreme short-term drought on grassland and shrubland ecosystems across six continents with a level of detail that was not previously possible. It is the first time an experiment this extensive has been undertaken to generate a baseline understanding of the potential losses of plant productivity in these vital ecosystems.
Published Path-following performance of autonomous ships
(via sciencedaily.com) Original source With recent requirements for reducing greenhouse gas emissions of autonomous ships, an emerging body of research is focused on assessing the path-following performance of maritime autonomous surface ships (MASS) at low speeds under adverse weather conditions. To combat the poor accuracy of traditional methods, in a new study, researchers investigated the path-following performance of MASS using a free-running computational fluid dynamics model. Their findings can help ensure safer autonomous navigation with reduced propulsion power.
Published Targeted household cleaning can reduce toxic chemicals post-wildfire
(via sciencedaily.com) Original source Wildfires create compounds called polycyclic aromatic hydrocarbons (PAHs), which are formed in the combustion process at high temperatures. These compounds are highly toxic. New research examined how long harmful chemicals found in wildfire smoke can persist and the most effective ways to remove them with everyday household cleaners.
Published Unraveling the mysteries of fog in complex terrain
(via sciencedaily.com) Original source While fog presents a major hazard to transportation safety, meteorologists have yet to figure out how to forecast it with the precision they have achieved for precipitation, wind and other stormy events. This is because the physical processes resulting in fog formation are extremely complex, Now researchers report their findings from an intensive study centered on a northern Utah basin and conceived to investigate the life cycle of cold fog in mountain valleys.
Published Western Cascades landscapes in Oregon historically burned more often than previously thought
(via sciencedaily.com) Original source Forests on the west slope of Oregon's Cascade Range experienced fire much more often between 1500 and 1895 than had been previously thought.
Published Finding new ways to adapt to a growing weather threat
(via sciencedaily.com) Original source Research reveals a steady increase in the number of people at risk from tropical cyclones and the number of days per year these potentially catastrophic storms threaten health and livelihoods. The findings could help relief agencies, development banks, and other organizations plan more effective strategies for mitigating extreme weather impacts.
Published Scientists uncover link between the ocean's weather and global climate
(via sciencedaily.com) Original source Scientists outline the first direct evidence linking seemingly random weather systems in the ocean with climate on a global scale. The team's work creates a promising framework for better understanding the climate system.
Published Genetic sequencing uncovers unexpected source of pathogens in floodwaters
(via sciencedaily.com) Original source Researchers report that local rivers and streams were the source of the Salmonella enterica contamination along coastal North Carolina after Hurricane Florence in 2018 -- not the previously suspected high number of pig farms in the region.
Published Snowflakes swirling in turbulent air as they fall through a laser light sheet
(via sciencedaily.com) Original source A winter wonderland calls to mind piles of fluffy, glistening snow. But to reach the ground, snowflakes are swept into the turbulent atmosphere, swirling through the air instead of plummeting directly to the ground. Researchers found that regardless of turbulence or snowflake type, acceleration follows a universal statistical pattern that can be described as an exponential distribution.
Published Spike in dermatology visits for skin problems seen during summer of wildfires
(via sciencedaily.com) Original source New research suggests that air pollution may contribute to the development or worsening of skin conditions. The work points to the need to improve air quality to lower the burden of skin disease, especially for vulnerable communities.
Published Wildfires increasing across Eastern U.S.
(via sciencedaily.com) Original source Researchers examined 36 years of wildfire data in the eastern United States, focusing on fires that burned large areas. The overall trend for the region showed an increase in fire size, frequency, and shifts in seasonality and highlights a need for proactive management and individual preparedness for those living in this populous part of the country.
Published Understanding atmospheric flash droughts in the Caribbean
(via sciencedaily.com) Original source The word 'drought' typically conjures images of parched soil, dust-swept prairies, depleted reservoirs, and dry creek beds, all the result of weeks or seasons of persistently dry atmospheric conditions. In the sun-soaked islands in the Caribbean, however, drought conditions can occur much more rapidly, with warning signs appearing too late for mediation strategies to limit agriculture losses or prevent stresses on infrastructure systems that provide clean water to communities.
Published Positive tipping points must be triggered to solve climate crisis
(via sciencedaily.com) Original source Positive tipping points must be triggered if we are to avoid the severe consequences of damaging Earth system tipping points, researchers say.
