Boise State graduate students Gabriel Trisca, computer science, and Mark Robertson, geophysics, leave Friday to spend a full month at Summit Camp at Greenland’s highest point, where they will help test the capabilities of a unique NASA robot and gather radar data to help scientists better understand the extent of summer 2012’s unusual ice melt.
IISD analysis -- Regulating Carbon Emissions in Canada-- Oil and Gas Greenhouse Gas Regulations: The implications of alternative proposals.
Two researchers affiliated with the Virginia Tech College of Engineering have published a paper which reports that hot water recirculating systems touted as “green,” actually use both more energy and water than their standard counterparts. The research found that the “so-called green” hot water recirculation systems used more net water than the conventional systems after accounting for water needed to produce the extra energy.
In the spring following a forest fire, trees that survived the blaze explode in new growth and plants sprout in abundance from the scorched earth. For centuries, it was a mystery how seeds, some long dormant in the soil, knew to push through the ashes to regenerate the burned forest.
University of Washington engineers have found that using a grocery delivery service can cut carbon dioxide emissions by at least half when compared with individual household trips to the store.
Researchers at Florida State University have developed a new metric to measure seasonal Atlantic tropical cyclone activity that focuses on the size of storms in addition to the duration and intensity, a measure that may prove important when considering a hurricane’s potential for death and destruction. Just ask the survivors of Hurricane Sandy.
Virginia Tech researchers working in Botswana discovered that humans are passing antibiotic resistance to wildlife, especially in protected areas where numbers of humans are limited.
Potential for method to be used within a network of wetland monitoring programmes in Southeast Asia and globally for assessing shoreline security and stability.
Wood-burning cookstoves, used by millions of people worldwide, cause air pollution, disease and death. A team of university students studied the problem and came up with a simple, low-cost solution: better ventilation
It’s well known that wildfires can leave surface soil burned and barren. But a new team's fiery test found that the hotter the fire — and the denser the vegetation feeding the flames — the less the underlying soil heated up, an inverse effect which runs contrary to previous studies and conventional wisdom.
Since 1997, a shrubby perennial found only in East Texas has been on a waiting list to be officially declared by the U.S. Fish and Wildlife Service as threatened. A ruling on the fate of the Neches River rose-mallow is expected by 2016, but the future of the white-petaled, ruby-throated hibiscus may hinge on its past: The jury is still out on whether the showy plant is actually its very own species. Researchers will present their most recent findings on the matter on Tuesday, April 23, at the Experimental Biology 2013 conference in Boston.
For much of Asia, the pace of life is tuned to rhythms of monsoons. The summer rainy season is especially important for securing the water and food supplies for more than a billion people. Its variations can mean the difference between drought and flood. Now a Scripps Institution of Oceanography, UC San Diego-led study reports on a crucial connection that could drastically improve the ability of forecasters to reliably predict the monsoon a few months in advance.
In celebration of Earth Day, the Institute of Food Technologists (IFT) today released several resources that highlight the contributions of food science to a sustainable earth.
Researchers found pronounced regional differences in past temperature changes while assembling the most comprehensive study to date of temperature change of Earth's continents over the past 1,000 to 2,000 years.
A professor at the SUNY College of Environmental Science and Forestry has put aside nearly a century and a half of conventional wisdom with the rediscovery of a species of giant Amazonian fish.
Using a new laboratory technique to analyze fossil snail shells, scientists have gained insights into an abrupt climate shift that transformed the planet nearly 34 million years ago.
Scientists have identified subtle increases in the levels of industrial and domestic pollutants across the Central Appalachians, according to Steve Stephenson in his new book.

The area of the contiguous United States in moderate drought or worse fell below 50 percent for the first time since last June, according to the latest edition of the U.S. Drought Monitor.
In low doses, hydrogen sulfide, a substance implicated in several mass extinctions, could greatly enhance plant growth, leading to a sharp increase in global food supplies and plentiful stock for biofuel production, new University of Washington research shows.
Researchers illustrate how changes to farming could dramatically increase future costs of conservation.
A new study of climate change and wine grapes published this month in Proceedings of the National Academy of Sciences paints a dire picture for wine grapes and wildlife. Two Cornell University experts urge lovers of both not to panic. With some thoughtful adaptation, there’s still a plenty of room and resources for everyone.
Opportunities for social interaction--which are important for individual, economic and social well-being--are hampered in decentralized cities, even more than by fragmented urban layouts and long commute times, say researchers at the University of Utah.
With coastal areas bracing for rising sea levels, new research indicates that cutting emissions of certain pollutants can greatly slow down sea level rise. Reductions in the four pollutants that cycle comparatively quickly through the atmosphere could forestall the rate of sea level rise by roughly 25 to 50 percent.
In recent decades, glacier thinning at the edge of Antarctica has accelerated and added to sea level rise. New research led by the University of Washington indicates that the dramatic changes cannot be confidently attributed to human-caused global warming.
Researchers at Columbia Engineering and Boston University have developed the first method to map evaporation globally using weather stations, which will help scientists evaluate water resource management, assess recent trends of evaporation throughout the globe, and validate surface hydrologic models in various conditions.
Researchers at Sandia National Laboratories’ Combustion Research Facility, the University of Manchester, Bristol University, University of Southampton and Hong Kong Polytechnic have successfully measured reaction rates of a second Criegee intermediate, CH3CHOO, and proven that the reactivity of the atmospheric chemical depends strongly on which way the molecule is twisted. A paper describing the research findings titled “Direct Measurements of Conformer-Dependent Reactivity of the Criegee Intermediate CH3CHOO” is featured in the April 12 edition of Science magazine.
A new report on hydraulic fracturing (fracking) in California warns of possible water contamination and seismic activity near drilling sites, unless the oil-extraction method is tightly regulated.
With ocean life facing unprecedented threat from climate change, overfishing, pollution, invasive species and habitat destruction, a University of Florida researcher is helping coordinate national efforts to monitor marine biodiversity.
The certification of seafood as “sustainable” by the nonprofit Marine Stewardship Council is too lenient and discretionary, a study by a consortium of researchers has found.
University of Utah researchers developed a high-speed camera system that spent the past two winters photographing snowflakes in 3-D as they fell – and they don’t look much like those perfect-but-rare snowflakes often seen in photos.
A century from now researchers will gather data from a forest in Maryland to see how, during the previous 100 years, varying levels of species diversity affected its development and how the forest reacted to climate change. The information researchers garner could be critical for conservation, and they will have Smithsonian scientists who planted the entire forest back in 2013 to thank.
Researchers at The Ohio State University report a set of ice cores from Quelccaya Ice Cap in Peru which can serve as a "Rosetta Stone" for studying other ice cores from around the world.
If the sheet of ice covering Greenland were to melt in its entirety tomorrow, global sea levels would rise by 24 feet. Three million cubic kilometers of ice won’t wash into the ocean overnight, but researchers have been tracking increasing melt rates since at least 1979. Last summer, however, the melt was so large that similar events show up in ice core records only once every 150 years or so over the last four millennia.
Award-winning McGill researcher to share environmental insights through video series.
A new report from the Wildlife Conservation Society (WCS) looked at the vulnerability of 54 breeding bird species to climate change impacts occurring by the year 2050 in Arctic Alaska. The assessment found that two species, the gyrfalcon and common eider are likely to be “highly” vulnerable, while seven other species would be “moderately” vulnerable to anticipated impacts. Five species are likely to increase in number and benefit from a warming climate.
UAH climate dataset offers new products. Global climate trend since Nov. 16, 1978: +0.14 C per decade.
The largest harmful algae bloom in Lake Erie's recorded history was likely caused by the confluence of changing farming practices and weather conditions that are expected to become more common in the future due to climate change.
Surface appearances can be so misleading: In most forests, the amount of carbon held in soils is substantially greater than the amount contained in the trees themselves.
Researchers in Boston University’s Department of Earth and Environment recently looked into whether the effects of climate change can be found in the winning times of Boston Marathon runners.
