Published AI approach to drought zoning (via sciencedaily.com) Original source
A recent study shows that climate change may cause many areas in Canada to experience significant droughts by the end of the century. In response, the researchers have introduced an advanced AI-based method to map drought-prone regions.
Published Sharing risk to avoid power outages in an era of extreme weather (via sciencedaily.com) Original source
Heat waves, droughts, and fires place growing stress on the West's electric grid. New research suggests that more integrated management of electricity resources across the region could significantly reduce the risk of power outages and accelerate the transition to clean energy.
Published Renewable energy policies provide benefits across state lines (via sciencedaily.com) Original source
New research suggests U.S. states with clean energy policies provide benefits to their neighbors, including states without their own renewable energy policies.
Published Environmental laws failing to slow deforestation (via sciencedaily.com) Original source
Australia's environmental laws are failing to stop high rates of tree clearing to make way for agriculture, development and mining.
Published Incorporating humidity improves estimations of climate impacts on health (via sciencedaily.com) Original source
Governments, medical institutions and other bodies require accurate models on health-related matters in order to better organize their activities. Climate change has measurable impacts on society, including on human mortality. However, current models to assess the health impacts of climate change do not account for every environmental parameter, especially humidity, which could influence heat stress perceived by the human body, leaving room for improvement. Researchers have now incorporated humidity data from hundreds of cities into so-called heat stress indicators (HSIs) and assessed their performances in predicting heat-related deaths.
Published Demand for low-quality credits undermines the voluntary carbon market, study finds (via sciencedaily.com) Original source
Researchers have shown that the 20 companies retiring the most offsets from the voluntary carbon market -- or VCM -- over the past four years have largely relied on low-quality, low-cost credits. These include major oil companies, airlines and aircraft makers, automotive manufacturers, logistics operators, and others.
Published Action plan to help patients with lung disease cope with wildfire smoke (via sciencedaily.com) Original source
A multidisciplinary team has developed an action plan to help patients with respiratory diseases mitigate the consequences of poor air quality from wildfires.
Published Researchers develop index to quantify circular bioeconomy (via sciencedaily.com) Original source
As the world faces the challenges of mitigating climate change and providing resources for a growing population, there is increasing focus on developing circular economies for sustainable production. But to evaluate strategies and impacts, it is necessary to have reliable metrics. Researchers have now developed a Circularity Index that provides a comprehensive method to quantify circularity in bioeconomic systems. In a new paper, they outline the method and apply it to two case studies -- a corn/soybean farming operation and the entire U.S. food and agriculture system.
Published Forest loss intensifies climate change by increasing temperatures and cloud level, which leads to decrease of water (via sciencedaily.com) Original source
Researchers report that deforestation during the last two decades induced a higher warming and cloud level rise than that caused by climate change, which threatens biodiversity and water supply in African montane forests.
Published Urban street networks, building density shape severity of floods (via sciencedaily.com) Original source
The design of streets and layout of buildings have an impact on a city's resilience in the face of increasingly severe floods brought on by climate change. Researchers look at buildings and other urban structures as physicists consider elements in complex material systems. With this insight, the researchers have developed a new approach to urban flood modelling and found their results helpful in analyzing city-to-city variations in flood risk globally.
Published Preservation of organic carbon in the ocean floor (via sciencedaily.com) Original source
The preservation of organic carbon in marine sediments has long been a key question remaining unclear in understanding the long-term carbon cycling on Earth. Recently, scientists have gained new insights into the dynamic cycling of iron-bound organic carbon in subseafloor sediments.
Published New twist on synthesis technique promises sustainable manufacturing (via sciencedaily.com) Original source
Researchers developed a new method known as flash-within-flash Joule heating (FWF) that could transform the synthesis of high-quality solid-state materials, offering a cleaner, faster and more sustainable manufacturing process.
Published Nitrogen interventions as a key to better health and robust ecosystems (via sciencedaily.com) Original source
An international research team combined multidisciplinary methods to evaluate how nitrogen interventions could improve air quality and reduce nitrogen deposition. Their study found that interventions, such as improving fuel combustion conditions, increasing agricultural nitrogen use efficiency, and reducing food loss and waste, could significantly lower premature deaths attributed to air pollution, crop losses, and ecosystems risks.
Published Scottish and Irish rocks confirmed as rare record of 'snowball Earth' (via sciencedaily.com) Original source
The study found that the Port Askaig Formation, composed of layers of rock up to 1.1 km thick, was likely laid down between 662 to 720 million years ago during the Sturtian glaciation -- the first of two global freezes thought to have triggered the development of complex, multicellular life.
Published Exploring options for the sustainable management of phosphorus (via sciencedaily.com) Original source
A new study assessed the feasibility of recovering phosphorus from municipal wastewater as an alternative sustainable source of this non-renewable mineral.
Published Researchers discover smarter way to recycle polyurethane (via sciencedaily.com) Original source
Researchers have found a better method to recycle polyurethane foam from items like mattresses: They are not only able to break down PUR and separate the two main components -- they can do it in one go. This is great news for the budding industry that aims to chemically recover the original components of the material -- making their products cheaper and better.
Published Why isn't Colorado's snowpack ending up in the Colorado River? New research suggests the problem might be the lack of spring rainfall (via sciencedaily.com) Original source
The Colorado River and its tributaries provide water for hydropower, irrigation and drinking water in seven U.S. states and Mexico. But since 2000, water managers have struggled to predict how much water will come from the snowpack. The problem lies with the lack of rainfall in the spring, according to new research.
Published New research shows unprecedented atmospheric changes during May's geomagnetic superstorm (via sciencedaily.com) Original source
On May 11, a gorgeous aurora surprised stargazers across the southern United States. That same weekend, a tractor guided by GPS missed its mark. What do the visibility of the northern lights have in common with compromised farming equipment in the Midwest? A uniquely powerful geomagnetic storm, according to new research.
Published U.S. capable of achieving seafood independence (via sciencedaily.com) Original source
If the U.S. became seafood independent, or meet its entire seafood needs through its own production, it could offer opportunities for improving dietary outcomes as well as individual and national food security, particularly against disruptions in global supply chains. Through analyzing 50 years of regional and national consumption and production data, from 1970-2021, researchers found that the U.S. could achieve seafood independence, although 'achieving greater seafood independence would require shifts in consumer behavior, investments in infrastructure and continual adaptation in the face of climate change.'
Published As human activities expand in Antarctica, scientists identify crucial conservation sites (via sciencedaily.com) Original source
Establishing Key Biodiversity Areas in the Southern Ocean will be vital for safeguarding the ecosystem from the impact of human activities, researchers say.
