New insight into the Great Dying

Thu, 06/11/2020 - 18:45
The collapse of terrestrial ecosystems during Earth's most deadly mass extinction event was directly responsible for disrupting ocean chemistry, according to new research.

Could we run out of sand? Scientists adjust how grains are measured

Thu, 06/11/2020 - 16:41
How we account for sand is important for understanding how reefs, atolls and coastal regions will cope with the effects of climate change. Scientists have discovered models for measuring sand were giving incorrect information and have developed more accurate engineering models.

Crop pathogens 'remarkably adaptable'

Thu, 06/11/2020 - 16:41
Pathogens that attack agricultural crops show remarkable adaptability to new climates and new plant hosts, new research shows.

How stimulus dollars are spent will affect emissions for decades

Wed, 06/10/2020 - 22:20
The COVID-19 pandemic and subsequent lockdowns have led to a record crash in emissions. But it will be emission levels during the recovery.

Island 'drowning' is not inevitable as sea levels rise

Wed, 06/10/2020 - 22:20
An international study suggests islands composed of gravel material can evolve in the face of overtopping waves, with sediment from the beach face being transferred to the island's surface.

Bedrock type under forests greatly affects tree growth, species, carbon storage

Wed, 06/10/2020 - 22:20
A forest's ability to store carbon depends significantly on the bedrock beneath, according to researchers who studied forest productivity, composition and associated physical characteristics of rocks in the Appalachian ridge and Valley Region of Pennsylvania.

Climate change: Warm springtime's unwelcome legacy

Wed, 06/10/2020 - 22:20
A new study shows that the severe impact of the summer drought that hit Europe in 2018 was partly due to the spring heatwave that preceded it, which triggered early and rapid plant growth, depleting soil moisture.

Proposed seismic surveys in Arctic Refuge likely to cause lasting damage

Wed, 06/10/2020 - 20:50
Winter vehicle travel can cause long-lasting damage to the tundra, according to a new article. Scars from seismic surveys for oil and gas exploration in the Arctic National Wildlife Refuge remained for decades, according to the study. The findings counter assertions made by the Bureau of Land Management in 2018 that seismic exploration causes no 'significant impacts' on the landscape.

Extinct camelids reveal insights about North America's ancient savannas

Wed, 06/10/2020 - 19:10
A new study looking at extinct camelids -- ancestors of today's camels and llamas -- tells the story of North America's ancient savannas and highlights how past climatic and environmental conditions influenced the composition of mammalian faunas.

Considering health when switching to cleaner electricity

Wed, 06/10/2020 - 19:09
Power plants that burn coal and other fossil fuels emit not only planet-warming carbon dioxide, but also pollutants linked to breathing problems and premature death. Policies proposed to mitigate climate change, however, often fail to fully account for the health benefit of switching to cleaner technologies. Researchers show that emphasizing health concerns in such policies can alter the optimal locations of these upgrades. 

Antarctic sea-ice models improve for the next IPCC report

Wed, 06/10/2020 - 17:27
All the new coupled climate models project that the area of sea ice around Antarctica will decline by 2100, but the amount of loss varies considerably between the emissions scenarios.

New explanation for neutrino anomalies in Antarctica

Wed, 06/10/2020 - 02:07
A new article provides a new explanation for two recent strange events that occurred in Antarctica -- high-energy neutrinos appearing to come up out of the Earth on their own accord and head skyward.

Ancient micrometeoroids carried specks of stardust, water to asteroid 4 Vesta

Tue, 06/09/2020 - 23:19
Researchers have studied presolar materials that landed on a planet-like body. Their findings may help solve the mystery: where did all the water on Earth come from?

Heat and humidity battle sunshine for influence over the spread of COVID-19, researchers find

Tue, 06/09/2020 - 19:29
Researchers have found that while higher heat and humidity can slow the spread of COVID-19, longer hours of sunlight are associated with a higher incidence of the disease, in a sign that sunny days can tempt more people out even if this means a higher risk of infection.

Study tracks decades of life cycle changes in nonwoody plants

Tue, 06/09/2020 - 19:29
For 25 years, Carol Augspurger visited a patch of ancient woods near Urbana, Illinois to look at the same 25 one-square-meter plots of earth she first demarcated for study in 1993. Her 600,000+ observations revealed that herbaceous plants are shifting their schedules in response to climate change, with distinct patterns for early- and late-spring-emerging plants.

Water vapor in the atmosphere may be prime renewable energy source

Tue, 06/09/2020 - 19:29
A new study finds that water vapor in the atmosphere may serve as a potential renewable energy source in the future.

Patterns in permafrost soils could help climate change models

Tue, 06/09/2020 - 16:51
A team of scientists spent the past four summers measuring permafrost soils across a 5,000 square-mile swath of Alaska's North Slope. While working to buildup a much-needed soil dataset, their measurements revealed an important pattern: The hydrologic properties of different permafrost soil types are very consistent, and can be predicted based on the surrounding landscape.

California's climate refugia: Mapping the stable places

Tue, 06/09/2020 - 16:51
Some landscapes can hold their own against climate change better than others. A new study maps these places, called 'climate refugia,' where existing vegetation is most likely to buffer the impacts of climate change through the end of the century.

Scientists lament 'Humpty Dumpty' effect on world's spectacular, rare wildlife

Tue, 06/09/2020 - 16:50
A new study reveals how runaway human population growth collapses the role of wildlife in the world's ecosystems.

Nature's 'slow lanes' offer hope for species feeling heat of climate change

Tue, 06/09/2020 - 16:50
Pockets of landscape less prone than adjacent areas to disturbances like fire and drought may hold the key for scientists, conservationists and land managers seeking to preserve vulnerable species in a changing climate.
