Published Nature-based solutions to disaster risk from climate change are cost effective
(via sciencedaily.com) Original source A new global assessment of scientific literature finds that nature-based solutions (NbS) are an economically effective method to mitigate risks from a range of disasters -- from floods and hurricanes to heatwaves and landslides -- which are only expected to intensify as Earth continues to warm.
Published Scientists use machine learning to predict diversity of tree species in forests
(via sciencedaily.com) Original source Researchers used machine learning to generate highly detailed maps of over 100 million individual trees from 24 sites across the U.S. These maps provide information about individual tree species and conditions, which can greatly aid conservation efforts and other ecological projects.
Published Microplastic pollution increases sea foam height and stability
(via sciencedaily.com) Original source Researchers examine the specific impacts of microplastics on the geophysics of sea foam formation in the critical zone where water meets air in the top layer of the ocean. They devised two simulations for their work -- a column filled with sea water injected with air and a laboratory-scale breaking wave channel to test the impacts of wave height on sea foam in the surface microlayer -- and tested their effects on sea foam formation, stability, and duration.
Published Weather experts discover new effect of storm -- in a teacup
(via sciencedaily.com) Original source A new study reveals that Storm Ciaran cut an invisible path of mayhem across southern Britain last autumn, destroying any possibility that 20 million people could have a proper cup of tea at breakfast. The storm's record-breaking low pressure meant the boiling point of water was below the crucial 100 degrees Celsius required for a decent cuppa.
Published Scientists discover missing piece in climate models
(via sciencedaily.com) Original source As the planet continues to warm due to human-driven climate change, accurate computer climate models will be key in helping illuminate exactly how the climate will continue to be altered in the years ahead.
Published Loss of oxygen in lakes and oceans a major threat to ecosystems, society, and planet
(via sciencedaily.com) Original source Oxygen is a fundamental requirement of life, and the loss of oxygen in water, referred to as aquatic deoxygenation, is a threat to life at all levels. In fact, researchers describe how ongoing deoxygenation presents a major threat to the stability of the planet as a whole.
Published 2023 Rolling Hills Estates landslide likely began the winter before
(via sciencedaily.com) Original source Landslides triggered by intense rainfall can sometimes be predicted along with incoming storms, but dry-season landslides often take people by surprise. The July 2023 Rolling Hills Estates landslide that destroyed 12 homes seemed to come out of nowhere, but new research shows it began as early as December 2022. Researchers are developing a database that will enable scientists to plug in new data to monitor potential landslides in real time and possibly predict them.
Published Scientists call for 'major initiative' to study whether geoengineering should be used on glaciers
(via sciencedaily.com) Original source Scientists have released a landmark report on glacial geoengineering -- an emerging field studying whether technology could halt the melting of glaciers and ice sheets as climate change progresses.
Published Researchers explore the role of children in community participatory planning process
(via sciencedaily.com) Original source Child-friendly cities prioritize safe environments, healthcare, education, green spaces, and children's participation in decision-making processes. However, children are consulted only for ideas and often excluded from public spaces. A study tackled pedestrian safety around school zones using child-inclusive participatory planning. Their approach included field work, community mapping, and collaborative solution development. Children effectively identified safety risks, shaping a robust safety plan with potential to significantly enhance community safety.
Published New study provides enhanced understanding of tropical atmospheric waves
(via sciencedaily.com) Original source Findings has critical implications for predicting extreme weather events such as hurricanes and heavy rainfall.
Published Planted mangroves' ability to store carbon
(via sciencedaily.com) Original source Ecologists have published new findings on how planted mangroves can store up to 70% of carbon stock to that found in intact stands after only 20 years.
Published The Gulf Stream is wind-powered and could weaken from climate change
(via sciencedaily.com) Original source New evidence of changes to the Gulf Stream during the last ice age could indicate additional sensitivity to future climatic changes, finds a new study.
Published Global database reveals large gaps in our knowledge of four-footed animals
(via sciencedaily.com) Original source Researchers developed TetrapodTraits -- a global database of animals with four feet -- which can now be applied for better ecology, evolution and conservation research.
Published First local extinction in the US due to sea level rise, study suggests
(via sciencedaily.com) Original source The United States has lost its only stand of the massive Key Largo tree cactus in what researchers believe is the first local extinction of a species caused by sea level rise in the country.
Published Groundbreaking study reveals oceanic seabirds chase tropical cyclones
(via sciencedaily.com) Original source A new study reveals that the rare Desertas Petrels (Pterodroma deserta), a wide-ranging seabird in the North Atlantic, exhibit unique foraging behaviors during hurricane season. Contrary to other pelagic seabirds, these petrels do not avoid intense tropical cyclones but instead exploit the dynamic conditions for their benefit, providing new insights into the impact of cyclones on open ocean marine life.
Published Engine wear risk as planes swallow more dust waiting to land
(via sciencedaily.com) Original source Planes flying into one of the world's busiest airports are ingesting around 10kg of dust per 1,000 flights.
Published Weaker ocean circulation could enhance carbon dioxide buildup in the atmosphere, study finds
(via sciencedaily.com) Original source Scientists may have to rethink the relationship between the ocean's circulation and its long-term capacity to store carbon, new research suggests. As the ocean gets weaker, it could release more carbon from the deep ocean into the atmosphere -- rather than less, as some have predicted.
Published Exploring the radiative effects of precipitation on Arctic amplification and energy budget
(via sciencedaily.com) Original source While, in theory, precipitation impacts the Earth's radiation budget, the radiative effects of precipitation (REP) are poorly understood and excluded from most climate models. Hence, a new study examined the role of REP in the global and regional energy budgets and hydrological cycles, finding that REP significantly contributes to temperature and precipitation variations at different geographical scales, especially in the Arctic warming. This highlights the relevance of including REP in climate modeling for improved accuracy.
Published The dawn of the Antarctic ice sheets
(via sciencedaily.com) Original source In recent years global warming has left its mark on the Antarctic ice sheets. The 'eternal' ice in Antarctica is melting faster than previously assumed, particularly in West Antarctica more than East Antarctica. The root for this could lie in its formation, as an international research team has now discovered: sediment samples from drill cores combined with complex climate and ice-sheet modelling show that permanent glaciation of Antarctica began around 34 million years ago -- but did not encompass the entire continent as previously assumed, but rather was confined to the eastern region of the continent (East Antarctica).
Published How dust pollution from shrinking Great Salt Lake affects communities disproportionately
(via sciencedaily.com) Original source Exposure to wind-blown dust from exposed playa of the Utah lake is worse in Hispanic neighborhoods, according to new research. Findings suggest restoring the lake could ease social inequities associated with air pollution.
