The western United States relies on mountain snow for its water supply. Water stored as snow in the mountains during winter replenishes groundwater and drives river runoff in spring, filling reservoirs for use later in summer. But how could a warming globe and a changing climate interrupt this process?
A research team confirms that 97 percent of climate scientists agree that climate change is caused by humans. The group includes Sarah Green, a chemistry professor at Michigan Technological University, and is led by John Cook from the University of Queensland.
Must greater prosperity necessarily lead to a greater carbon footprint and increased greenhouse gas emissions? "In theory, no, but in practice this seems to be the case", says researcher Max Koch from Lund University in Sweden. His study of 138 countries is the first ever to take a global approach to the connections between growth, prosperity and ecological sustainability. The study was recently published in the journal article Global Environmental Change.
A University of Wyoming researcher contributed to a paper that has apparently solved an age-old riddle of how constituent continents were arranged in two Precambrian supercontinents -- then known as Nuna-Columbia and Rodinia. It's a finding that may have future economic implications for mining companies.
Dramatic improvements in air quality in U.S. cities since the 1990s may not be enough to ensure normal lung function in children, according to new research published in the April 15 American Journal of Respiratory and Critical Care, a journal of the American Thoracic Society.
Researchers at the University of Georgia’s Savannah River Ecology Laboratory warn that the extinction to two amphibian species—the southern toad and the southern leopard frog—may be hastened by the combined effects of climate change and copper-contaminated wetlands.
The massive icefield that feeds Alaska’s Mendenhall Glacier may be gone by 2200 if warming trend predictions hold true, according to University of Alaska Fairbanks researchers.
Research finds massive phosphorus buildup.
Tulane University has expanded its Nitrogen Reduction Challenge to allow more entrepreneurs, researchers and inventors the chance to win $1 million.
Just like humans, when plants are cut they clot at the site of the wound. Just how they do it is has been a botanical mystery until now. Two University of Delaware researchers have uncovered the enzymes that produce this response. The findings will be published on Monday in Nature Plants.
Research shows extraordinary commitment to science and soil physics and support of soil physicists
New simulations by researchers at the University of Warwick and UCL’s Institute of Archaeology of plant evolution over the last 3000 years have revealed an unexpected limit to how far useful crops can be pushed to adapt before they suffer population collapse. The result has significant implications for how growers, breeders and scientists help agriculture and horticulture respond to quickening climate change.
While Florida and Alaska are on the opposite ends of the spectrum, they share mutual concerns of the imminent challenges presented by environmental changes. The rapid melting of the Arctic ice is threatening coastal locations globally, and impacts include increased flooding from sea-level rise in Florida to infrastructure instability from permafrost melting in Alaska.
In a joint North European and North American study led by Umeå researcher Christer Nilsson, a warning is issued of underdocumented results of ecological restorations. The researchers show that continuous and systematic evaluations of cost-efficiency, planning, implementations and effects are necessary in order to make use of experiences in future projects. The results have been published in the journal Ecology and Society.
Longer monsoon seasons with increased daily rainfall, aspects of climate change, are contributing to reduced tea yield in regions of China, with implications for crop management and harvesting strategies, according to findings by a global interdisciplinary team led by Tufts University researchers and published online today in Climate.
Plants share their carbohydrates with arbuscular mycorrhizal fungi that colonize their roots and, in exchange, these fungi provide their hosts with nitrogen and phosphorous. By exploiting this relationship, scientists may be able to increase the biomass production of bioenergy crops and the yield of food crops and to reduce the required fertilizer inputs. This could improve the environmental sustainability of agricultural production systems according to professor Heike Bücking of South Dakota State University.
While farm soil grows the world’s food and fiber, scientists are examining ways to use it to sequester carbon and mitigate greenhouse gas emissions.
The world has more carbon dioxide than it needs, and a team of Brown University chemists has come up with a potential way to put some of it to good use.
A multi-university collaboration has issued a report on steps to reduce harmful algal blooms in Lake Erie
