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.

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.

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.

Scientists uncover hidden forces causing continents to rise      (via sciencedaily.com)     Original source 

Scientists have answered one of the most puzzling questions in plate tectonics: how and why 'stable' parts of continents gradually rise to form some of the planet's greatest topographic features.

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.

The race to discover biodiversity: 11 new marine species and a new platform for rapid species description      (via sciencedaily.com)     Original source 

A new paper describes a ground-breaking experiment that united 25 independent taxonomists from 10 countries. The initiative boasts the discovery of 11 new marine species from all over the globe, occurring at depths from 5.2 to 7081 meters. It also represents a significant step forward in accelerating the pace at which new marine species are described and published.

A new way of thinking about the economy could help protect the Amazon, and help its people thrive      (via sciencedaily.com)     Original source 

To protect the Amazon and support the wellbeing of its people, its economy needs to shift from environmentally harmful production to a model built around the diversity of indigenous and rural communities, and standing forests.

Greenland fossil discovery reveals increased risk of sea-level catastrophe      (via sciencedaily.com)     Original source 

Seeds, twigs, and insect parts found under two miles of ice confirm Greenland's ice sheet melted in the recent past, the first direct evidence that the center -- not just the edges -- of the two-mile-deep ice melted away in the recent geological past. The new research indicates that the giant ice sheet is more fragile than scientists had realized until the last few years -- and reveals increased risk of sea-level catastrophe in a warmer future.

Link between global warming and rising sea levels      (via sciencedaily.com)     Original source 

A new study suggests that Earth's natural forces could substantially reduce Antarctica's impact on rising sea levels, but only if carbon emissions are swiftly reduced in the coming decades. By the same token, if emissions continue on the current trajectory, Antarctic ice loss could lead to more future sea level rise than previously thought.

Sea level changes shaped early life on Earth, fossil study reveals      (via sciencedaily.com)     Original source 

Shifts in the Earth's continental plates that drove long-term changes in sea level set the stage for the evolution of the earliest animals on Earth, a study suggests.

Recent volcanic 'fires' in Iceland triggered by storage and melting in crust      (via sciencedaily.com)     Original source 

Scientists have detected geochemical signatures of magma pooling and melting beneath the subsurface during the 'Fagradalsfjall Fires', that began on Iceland's Reykjanes peninsula in 2021. Samples show that the start of the eruption began with massive pooling of magma, contrasting initial hypothesis for magma ascent straight from the mantle.

North Sea oil and gas extraction spikes pollution by 10,000 percent, study finds      (via sciencedaily.com)     Original source 

North Sea oil and gas extraction can cause pollution to spike by more than 10,000 percent within half a kilometer around off-shore sites, a study has found. The research has uncovered the true impact on Britain's seabed life -- with the number of species plummeting nearly 30 percent near platforms.
