Tea Party Republicans are distrustful of scientists as a source of information on environmental issues, and public radio listeners are more likely to trust scientists, new survey research from the Carsey Institute has found. The research found almost two-thirds of NH residents trust scientists.
Many have assumed that warmer winters as a result of climate change would increase the growth of trees and shrubs because the growing season would be longer. But shrubs achieve less yearly growth when cold winter temperatures are interrupted by temperatures warm enough to trigger growth.
The University of Wisconsin-Madison, home of pioneering ecologists who studied lakes, forests, wetlands and prairies, is playing a key role in the next wave of ecological research: large teams of scientists confronting the dilemma of a changing climate on a shrinking planet.
Scientists delivered a mostly negative forecast for how climate change will affect Ohioans during the next year or so, and well beyond. But Ohio may fare better than its neighbors in one respect: its farmers will likely suffer less than those in the rest of the Corn Belt.
Two major droughts within a five-year period have done significant damage to the Amazon forest in Brazil, but analyzing how the forest has responded may help researchers predict the long-term impact of global warming, according to research scientist Izaya Numata of the Geographic Information Science Center of Excellence at South Dakota State University.
A three-stone fire is the traditional way of heating food and water, but it also poses risks and other problems. Users can be burned or scalded. Smoke can’t be controlled. The fires are inefficient and waste a lot of fuel. A Clarkson University researcher explains why this matters now.
Environmental advocates push for regulation. Industry responds with caution, concerned about associated costs, while the public chooses sides. But research by Clarkson University Associate Professor of Economics Martin Heintzelman promises to diffuse some of that tension.
An Arizona State University research team found that releasing excess heat from air conditioners running during the night resulted in higher outside temperatures, worsening the urban heat island effect and increasing cooling demands.
As the shale gas boom continues, the atmosphere receives more methane, adding to Earth’s greenhouse gas problem. Robert Howarth, greenhouse gas expert and ecology and environmental biology professor, fears that we may not be many years away from an environmental tipping point – and disaster.
The latitude at which tropical cyclones reach their greatest intensity is gradually shifting from the tropics toward the poles at rates of about 33 to 39 miles per decade, according to a study published today (May 14, 2014) in the journal Nature.
GAINESVILLE, Fla. --- A 5-million-year-old saber-toothed cat, the world’s oldest grape and a bizarre hermit crab were among more than 100 new species discovered by University of Florida scientists last year.
A new study from the University of Iowa reports Iowa's air quality falls within government guidelines for cleanliness, based on data gathered at five locations statewide. The study analyzed air quality and pollution sources in the state and is the first to compare air quality in urban versus rural areas. Results appear in the journal Environmental Science: Processes and Impacts.
Scientists re-examined 100 world-wide monitoring studies and were surprised to discover that, over decades, the number of species in many places has not changed much—or has increased. But the researchers did discover that almost 80% of the communities showed changes in species composition. This shows that a rapid global turnover of species is happening, resulting in novel biological communities. The scientists conclude that biodiversity change may be as large a concern as biodiversity loss.
There's an established, accepted and effective system for sustainable management of northern hardwood forests. The only thing is, although they give lip service, almost no one is using it.
Bags meet requirements of disintegrating to particles less than 2 millimeters in size in 180 days. Since the bags are made of all-natural components, they can be composted just like any other plant-based material.
Since the rise in the use of hydraulic fracturing of shale to produce natural gas and oil, many have debated the merits and detractions of the practice. Members of the Society of Toxicology (SOT) outline how toxicological sciences can be used to determine what risks may or may not be associated with fracking.
Visitors to the country’s National Parks may be seeking tranquil communion with nature, but what they sometimes encounter is the noise of airplanes and helicopter tours. In a study to be presented at the 167th meeting of the ASA, researchers with the U.S. Department of Transportation report on recent results of a joint FAA and National Park Service study to assess potential effects of such flights on the experience of park visitors.
Kansas Forest Service fire training specialist explains why fires are more difficult and costly to extinguish.
Due to climate change, "impacts in the Southwest will especially be felt in terms of water scarcity and more days of extreme heat," says Nancy Grimm, ASU life sciences professor and author of two chapters in the new National Climate Assessment report.

Although torrential rainfall has inundated the Southeast region this spring, there is something you can do in your own backyard to help prevent damage from flooding and runoff. Plant a rain garden.
New assessment of national, regional impacts shows challenges ahead for the U.S.
Jerry M. Melillo, Distinguished Scientist at the Ecosystems Center of the Marine Biological Laboratory (MBL) will join John Holdren, Assistant to the U.S. President for Science and Technology, and other administration officials, to release the Third National Climate Assessment at the White House today, Tuesday, May 6.
A new, absorbable material from Empa wood research could be of assistance in future oil spill accidents: a chemically modified nanocellulose sponge. The light material absorbs the oil spill, remains floating on the surface and can then be recovered. The absorbent can be produced in an environmentally-friendly manner from recycled paper, wood or agricultural by-products.
Ozone pollution across the continental United States will become far more difficult to keep in check as temperatures rise, according to new research led by NCAR. The detailed study shows that Americans face the risk of a 70 percent increase in unhealthy summertime ozone levels by 2050.
New research by a team of Florida State University scientists shows the first detailed look at global land surface warming trends over the last 100 years, illustrating precisely when and where different areas of the world started to warm up or cool down.
Inbreeding is killing off the wolves of Isle Royale National Park, and as a result, the moose are proliferating, threatening the vegetation on the remote Lake Superior island.
Due to increased interest in drilling for hydrocarbons in the Arctic and the associated environmental concerns, Woods Hole Oceanographic Institution researchers are working to evaluate whether broadband active acoustic techniques can be used to remotely detect oil spills under sea ice.
1) Reducing soot. 2) Hydropower. 3) Understanding driver behavior. 4) A performance record in high-temperature superconducting wires.
More than a mile beneath the ocean’s surface, as dark clouds of mineral-rich water billow from seafloor hot springs called hydrothermal vents, unseen armies of viruses and bacteria wage war.
Amphibians in the West's high-mountain areas find themselves caught between climate-induced habitat loss and predation from introduced fish. A novel combination of tools could help weigh where amphibians are in the most need of help.
The Wildlife Conservation Society’s 96 Elephants campaign is urging the popular PBS program “Antiques Roadshow” to stop its on-air appraisals of ivory.
It’s broadly understood that the world’s oceans play a crucial role in the global-scale cycling and exchange of carbon between Earth’s ecosystems and atmosphere. Now scientists at Scripps Institution of Oceanography at UC San Diego have taken a leap forward in understanding the microscopic underpinnings of these processes.
Scientists are beginning to talk about re-engineering crop plants so that, like legumes, they will have on-site nitrogen-fixing systems, either in root nodules or in the plant cells themselves. The structure of a protein called NolR that acts as a master off-switch for the nodulation process, published in the April 29 issue of PNAS, brings them one step closer to this goal.
Populations of large wildlife are declining around the world, while zoonotic diseases (those transmitted from animals to humans) are on the rise. A team of Smithsonian scientists and colleagues have discovered a possible link between the two. They found that in East Africa, the loss of large wildlife directly correlated with a significant increase in rodents, which often carry disease-causing bacteria dangerous to humans.
On Earth Day—Tuesday, April 22—the Stony Brook campus community, and the global twitter-verse came together – virtually and in person – with Stony Brook University’s three Indianapolis Prize finalists: Russell A.
