Aerosol pollution, greenhouse gases must be reduced simultaneously to keep forest fires in check      (via sciencedaily.com)     Original source 

If we want cleaner air, fewer forest fires, and less severe climate change, a new study shows we must reduce aerosol pollution and greenhouse gases like carbon dioxide at the same time.

Some species may tolerate climate change better than expected      (via sciencedaily.com)     Original source 

A new model reassesses the proportion of terrestrial and marine species threatened with extinction by climate change. While the forecasts of traditional models estimate that the diversity of terrestrial species in tropical areas could decrease by 54% between now and 2041-2060, this model is more moderate, predicting a decrease of 39%. Nevertheless, this proportion remains alarming and confirms the importance of taking urgent measures to mitigate climate change and its impact on biodiversity.

The secret sex life of coral revealed      (via sciencedaily.com)     Original source 

Corals play an essential role in ocean ecosystems, and like many organisms, they are under threat from climate change and other human activities. To better protect coral, it's first necessary to understand them, in particular their reproductive life cycle, which only happens once a year. For the first time, researchers have produced a model for coral spawning, based on various environmental factors. They achieved this by tapping an often overlooked source of aquatic knowledge, an aquarium.

Improved refrigeration could save nearly half of the 1.3 billion tons of food wasted each year globally      (via sciencedaily.com)     Original source 

A new study concludes that nearly half of the food waste, about 620 million metric tons, could be eliminated by fully refrigerated food supply chains worldwide. At the same time, fully refrigerated supply chains, or 'cold chains,' could cut food waste-related emissions of climate-warming greenhouse gases by 41% globally, according to a new study.

Prenatal exposure to air pollution associated with increased mental health risks      (via sciencedaily.com)     Original source 

A baby's exposure to air pollution while in the womb is associated with the development of certain mental health problems once the infant reaches adolescence, new research has found. The study examined the long-term mental health impact of early-life exposure to air and noise pollution.

Understanding the mechanisms for local amplification of 2024 tsunamis in Iida Bay      (via sciencedaily.com)     Original source 

Researchers uncover the unique mechanisms that resulted in severe tsunamis in Iida Bay caused by the 2024 Noto Peninsula Earthquake. The recent tsunamis in Iida Bay were locally amplified due to various factors, including ocean floor topology, the shape of the coastline, the location of coastal facilities, and seismic mechanisms associated with earthquakes, report scientists.

Study suggests 'biodegradable' teabags don't readily deteriorate in the environment and can adversely affect terrestrial species      (via sciencedaily.com)     Original source 

New research looked at commonly available teabags made using three different compositions of polylactic acid (PLA), which is derived from sources such as corn starch or sugar cane. The teabags were buried in soil for seven months, and a range of techniques were then used to assess whether -- and to what extent -- they had deteriorated. The results showed that teabags made solely from PLA remained completely intact. However, the two types of teabags made from a combination of cellulose and PLA broke down into smaller pieces, losing between 60% and 80% of their overall mass and with the PLA component remaining.

New research shows soil microorganisms could produce additional greenhouse gas emissions from thawing permafrost      (via sciencedaily.com)     Original source 

As the planet has warmed, scientists have long been concerned about the potential for harmful greenhouse gasses to seep out of thawing Arctic permafrost. Recent estimates suggest that by 2100 the amount of carbon dioxide and methane released from these perpetually frozen lands could be on par with emissions from large industrial countries. However, new research led by a team of microbiome scientists suggests those estimates might be too low.
