Global warming doubles risk of extreme La Niña event, research shows

The risk of extreme La Niña events in the Pacific Ocean could double due to global warming, new research has shown.

Study shows Brazil's Soy Moratorium still needed to preserve Amazon

Soybeans grow near a forested area in the Brazilian state of Mato Grosso. Under the Soy Moratorium, major trading companies do not purchase soybeans produced in the Brazilian Amazon on recently deforested areas.Today, fewer chicken nuggets can trace their roots to cleared Amazon rain forest.

Two lakes beneath the ice in Greenland, gone within weeks

In April 2014, researchers flew over a site in southwest Greenland to find that a sub-glacial lake had drained away. This photo shows the crater left behind, as well as a deep crack in the ice.Researchers who are building the highest-resolution map of the Greenland Ice Sheet to date have made a surprising discovery: two lakes of meltwater that pooled beneath the ice and rapidly...

Vegetation can help prevent soil erosion due to wind

Dust from soil erosion due to wind can affect human health, traffic, and, on a larger scale, climate. Investigators compared different models that quantify how the wind energy spreads over...

Warming climate likely will change the composition of northern forests, U of M study shows

The University of Minnesota's B4WarmEd project used heat lamps and warming coils to simulate climate change in plots 10 feet in diameter.Visitors to northern forests in coming decades probably will see a very different set of trees as the climate warms, a new University of Minnesota study shows.

Study: Melting glaciers have big carbon impact

Scientists have done field work in Tibet and Alaska, among other places as part of this study.As Earth warms and glaciers all over the world begin to melt, researchers and public policy experts have focused largely on how all of that extra water will contribute to...

Yellowstone's thermal springs -- their colors unveiled

This is a photograph of Morning Glory Pool from Aug. 23, 2012.Researchers at Montana State University and Brandenburg University of Applied Sciences in Germany have created a simple mathematical model based on optical measurements that explains the stunning colors of Yellowstone...

How will climate change transform agriculture?

Climate change impacts will require major but very uncertain transformations of global agriculture systems by mid-century, according to new research from the International Institute for Applied Systems Analysis.

Report: Clearing rainforests distorts wind and water, packs climate wallop beyond carbon

A new study released today presents powerful evidence that clearing trees not only spews carbon into the atmosphere, but also triggers major shifts in rainfall and increased temperatures worldwide that...

Colorado River Delta greener after engineered pulse of water

Water being released from Morelos Dam in the first environmental release of water to the Colorado River Delta. The Minute 319 pulse flow of water started March 23, 2014 and ended May 18, 2014.The engineered spring flood that brought water to previously dry reaches of the lower Colorado River and its delta resulted in greener vegetation, the germination of new vegetation along the...

Australia's coastal observation network may aid in understanding of extreme ocean events

A network of nine reference sites off the Australian coast is providing the latest physical, chemical, and biological information to help scientists better understand Australia's coastal seas, according to a...

Climate models disagree on why temperature 'wiggles' occur

A new Duke University-led study finds that most climate models likely underestimate the degree of decade-to-decade variability occurring in mean surface temperatures as Earth's atmosphere warms. The models also provide inconsistent explanations of why this variability occurs...

Small drop in sea level had big impact on southern Great Barrier Reef

University of Sydney researchers have analysed samples from One Tree Reef in the southern Great Barrier Reef and discovered a dramatic slow down following a small fall in sea level.The idea that coral reefs have formed over millennia in a continuous process has been challenged by a study of the southern Great Barrier Reef. The research, led by the...

Researchers introduce macrosystems approach to study stream ecology

Walter Dodds, Kansas State University distinguished professor of biology, is leading a research team in creating the Stream Biome Gradient Concept, which is a way to compare streams in different climates and different continents.Kansas State University scientists and collaborators have developed a new method for studying a variety of streams -- including tropical, prairie or forested streams -- across continents.

ORNL model explores location of future US population growth

This 3-D visualization represents projected changes in US population between 2010 and 2050 as predicted by a new Oak Ridge National Laboratory model. Areas seen in red indicate higher levels of population growth, whereas the vertical spikes signify population growth with new land development.Researchers at the Department of Energy's Oak Ridge National Laboratory have developed a population distribution model that provides unprecedented county-level predictions of where people will live in the U.S. in...

Geophysicists find the crusty culprits behind sudden tectonic plate movements

Yale-led research may have solved one of the biggest mysteries in geology -- namely, why do tectonic plates beneath the Earth's surface, which normally shift over the course of tens...

Nearly half the systems crucial to stability of planet compromised

Almost half of the processes that are crucial to maintaining the stability of the planet have become dangerously compromised by human activity. That is the view of an international team...

Birds sensed severe storms and fled before tornado outbreak

This golden-winged warbler spends the breeding season in the Cumberland Mountains of Tennessee.Golden-winged warblers apparently knew in advance that a storm that would spawn 84 confirmed tornadoes and kill at least 35 people last spring was coming, according to a report in...

Pilot plant for the removal of extreme gas charges from deep waters installed

This is the pit Lake Guadiana in the former mining area Herrerias in Andalusia, Spain.Being part of the mining area Herrerias in Andalusia, deep waters of Pit Lake Guadiana show extremely high concentration of dissolved carbon dioxide (CO2). In the case of a spontaneous...

Improving forecasts for rain-on-snow flooding

Many of the worst West Coast winter floods pack a double punch. Heavy rains and melting snow wash down the mountains together to breach riverbanks, wash out roads and flood...

Policy action urgently needed to protect Hawaii's dolphins

The best way to protect wild spinner dolphins in Hawaii while also maintaining the local tourism industry that depends on them is through a combination of federal regulations and community-based...

Ancient, hydrogen-rich waters discovered deep underground at locations around the world

Energy-rich waters discharge kilometers below the surface in a South African mine.A team of scientists, led by the University of Toronto's Barbara Sherwood Lollar, has mapped the location of hydrogen-rich waters found trapped kilometres beneath Earth's surface in rock fractures in...
