Humpbacks are among animals who manufacture and wield tools      (via sciencedaily.com)     Original source 

Researchers suggest a new designation of the humpback whales they study: tool wielders. Researchers have known that humpback whales create "bubble-nets" to hunt, but they have learned that the animals don't just create the bubble-nets; they manipulate this unique tool in a variety of ways to maximize their food intake in Alaskan feeding grounds.

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.

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.

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.

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.

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.

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.

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.

It's a rave: Underground acoustics amplify soil health      (via sciencedaily.com)     Original source 

Barely audible to human ears, healthy soils produce a cacophony of sounds in many forms -- a bit like an underground rave concert of bubble pops and clicks. Special recordings made by ecologists show this chaotic mixture of soundscapes can be a measure of the diversity of tiny living animals in the soil, which create sounds as they move and interact with their environment.
