Boreal forest and tundra regions worst hit over next 500 years of climate change, study shows      (via sciencedaily.com)     Original source 

Modelling climate change over a 500 year period shows that much of the boreal forest, the Earth's northernmost forests and most significant provider of carbon storage and clean water, could be seriously impacted, along with tundra regions, treeless shrublands north of the boreal forest that play a significant role in regulating the Earth's climate.

eDNA methods give a real-time look at coral reef health      (via sciencedaily.com)     Original source 

The study underscores the crucial role of microbes in maintaining coral reef health, akin to the human gut microbiome. Hurricanes and disease outbreaks affect coral reef water microbial communities, leading to changes that may support further reef decline. Microbial analysis enables prompt assessment of disturbances' impacts on coral reefs, facilitating timely interventions to support reef ecosystems. Environmental DNA (eDNA) analysis offers a noninvasive approach to study coral microbial communities and diagnose reef health.

Researchers envision sci-fi worlds involving changes to atmospheric water cycle      (via sciencedaily.com)     Original source 

Human activity is changing the way water flows between the Earth and atmosphere in complex ways and with likely long-lasting consequences that are hard to picture. Researchers enlisted water scientists from around the globe to write story-based scenarios about the possible futures humanity is facing but perhaps can't quite comprehend yet. The results are part of a creative pathway to understand atmospheric water research with an eye towards the potential economic and policy issues that may be just beyond the horizon.

Adult fish struggle to bounce back in marine protected areas      (via sciencedaily.com)     Original source 

Many marine protected areas are falling short of their most basic purpose: to rebuild struggling fish populations. In a new study, scientists looked at the age breakdown of reef fish in marine protected areas for the first time. They discovered in almost all of them, adult fish populations -- vital to spawning the next generation -- have either flatlined or declined.

'Tug of war' tactic enhances chemical separations for critical materials      (via sciencedaily.com)     Original source 

Lanthanide elements are important for clean energy and other applications. To use them, industry must separate mixed lanthanide sources into individual elements using costly, time-consuming, and waste-generating procedures. An efficient new method can be tailored to select specific lanthanides. The technique combines two substances that do not mix and that prefer different types of lanthanides. The process would allow for smaller equipment, less use of chemicals, and less waste production.

Experiencing extreme weather predicts support for policies to mitigate effects of climate change      (via sciencedaily.com)     Original source 

Most Americans report having personally experienced the effects of extreme weather, according to new survey data. An analysis finds that a reported exposure to extreme weather is associated with support for a half-dozen pro-environmental government policies that are intended to mitigate the effects of climate change and are contained in the Inflation Reduction Act of 2022.

California leads U.S. emissions of little-known greenhouse gas      (via sciencedaily.com)     Original source 

California, a state known for its aggressive greenhouse gas reduction policies, is ironically the nation's greatest emitter of one: sulfuryl fluoride. As much as 17% of global emissions of this gas, a common pesticide for treating termites and other wood-infesting insects, stem from the United States. The majority of those emissions trace back to just a few counties in California, finds a new study.

New step in tectonic squeeze that turns seafloor into mountains      (via sciencedaily.com)     Original source 

Researchers describe zircons from the Andes mountains of Patagonia. Although the zircons formed when tectonic plates were colliding, they have a chemical signature associated with when the plates were moving apart. The researchers think that the unexpected signature could be explained by the mechanics of underlying tectonic plates that hasn't yet been described in other models.
