Mature forests vital in frontline fight against climate change      (via sciencedaily.com)     Original source 

Mature forests have a key role to play in the fight against climate change -- extracting carbon dioxide (CO2) from the atmosphere and locking it into new wood.

Just say 'climate change' -- not 'climate emergency'      (via sciencedaily.com)     Original source 

The familiar terms 'climate change' and 'global warming' are more likely to resonate with people than other commonly used phrases.

Millions of years for plants to recover from global warming      (via sciencedaily.com)     Original source 

Catastrophic volcanic eruptions that warmed the planet millions of years ago shed new light on how plants evolve and regulate climate. Researchers reveal the long-term effects of disturbed natural ecosystems on climate in geological history and its implications for today.

Researchers find unexpectedly large methane source in overlooked landscape      (via sciencedaily.com)     Original source 

Researchers reported that upland landscapes were releasing some of the highest methane emissions yet documented among northern terrestrial ecosystems. The research was sparked when a potent greenhouse gas began ballooning under lawns in Fairbanks.

Researchers make breakthrough in understanding species abundance      (via sciencedaily.com)     Original source 

The key finding was that temperature and genome size, not body size, had the greatest influence on the maximum population growth rate of the diatoms. Yet body size still mattered in colder latitudes, conserving Bermann's Rule.

Record-breaking recovery of rocks that originated in Earth's mantle could reveal secrets of planet's history      (via sciencedaily.com)     Original source 

Scientists have recovered the first long section of rocks that originated in the Earth's mantle, the layer below the crust and the planet's largest component. The rocks will help unravel the mantle's role in the origins of life on Earth, the volcanic activity generated when it melts, and how it drives the global cycles of important elements such as carbon and hydrogen.

Detecting climate change using aerosols      (via sciencedaily.com)     Original source 

Researchers analyzed long-term aerosol satellite observation big data focusing on the Pacific Ocean downwind of China. Using a newly developed metric that considered aerosols as tracers, they detected altered atmospheric transport patterns associated with climate change. They observed that the distance of transboundary air pollution moving east from China had shortened. Thus, long-term satellite-based Earth observations are crucial for early climate change detection and accurate evaluation of this trend.

Sichuan Province earthquake offers lessons for landslide prediction from GNSS observations      (via sciencedaily.com)     Original source 

Using data collected from a 2022 magnitude 6.8 earthquake in Luding County in China's Sichuan Province, researchers tested whether Global Navigation Satellite System (GNSS) observations could be used for rapid prediction of earthquake-triggered landslides.

Forever chemical pollution can now be tracked      (via sciencedaily.com)     Original source 

Researchers developed a way to fingerprint organofluorine compounds -- sometimes called 'forever chemicals' --which could help authorities trace them to their source when they end up in aquifers, waterways or soil.

Monitoring of nature reserves via social media and deep learning      (via sciencedaily.com)     Original source 

Researchers have created a deep learning method to analyze social media images taken within protected green spaces to gain insights on human activity distribution as a way to monitor the ecological impacts of these activities.

Water delivered to the mantle by aluminum enriched hydrated slabs?      (via sciencedaily.com)     Original source 

Researchers found a notable effect of aluminum on the sound velocities of superhydrous phase B, a dense hydrous magnesium silicate and potential host of water in the deep Earth. Their results suggest that aluminous phase B could explain seismic velocity anomalies in the Earth's mantle transition region and uppermost lower mantle.

Plants offer fruit to insects to disperse dust-like seeds      (via sciencedaily.com)     Original source 

Fruit exist to invite animals to disperse the swallowed seeds. A research team found that plants targeting insects rather than birds or mammals for this service are more common than previously thought. These plants produce dust-like seeds and fruit suitable for the minute, ground-dwelling animals.

Elephants on the move: Mapping connections across African landscapes      (via sciencedaily.com)     Original source 

Elephant conservation is a major priority in southern Africa, but habitat loss and urbanization mean the far-ranging pachyderms are increasingly restricted to protected areas like game reserves. The risk? Contained populations could become genetically isolated over time, making elephants more vulnerable to disease and environmental change.
