The hypothesis that the Earth was completely covered in ice 635 million years ago has received a serious blow.
The scope and intensity of mercury pollution in the Great Lakes region is much greater than previously reported, but additional mercury controls should bring needed improvement.
Trends include a 170-percent increase in toxicity listings since 2006.
As the leaves change and temps drop, the crisp autumn air brings a whole new load of waste possibilities with the new season. As opposed to the scorching summer months coupled with UV rays that dry lawns and surge kilowatts of electricity through homes for cooling, fall brings gutter clutter and leaf waste – not to mention high kilowatt usage in parts of the world prone to freezing temps.
Researchers at the University of Montreal have developed a computer program that enables regulators to evaluate the ecological and economic tradeoffs between marine mammal conservation, whale watching and marine transportation activities in the Saint Lawrence Estuary.
Sanborn Regional School District in Kingston, N.H., has signed the world's first power purchase agreement for ultra-efficient solar hot air, which will reduce heating bills.
Drivers can now continue to keep the air-conditioning system on during the hot sunny days even when they stop the vehicle and switch off the engine. In collaboration with Green Power Industrial Ltd, Hong Kong Polytechnic University's (PolyU) Department of Electrical Engineering has developed an innovative air-conditioning system for vehicles that can turn scorching summer heat into cool air without a single drop of gasoline.
Many people in Bangladesh and other parts of Asia have been poisoned by drinking groundwater laced with arsenic—not introduced by humans, but leached naturally from sediments, and now being tapped by shallow drinking wells. In recent years, to avoid the problem, deeper wells have been sunk 500 feet or more to purer waters—but fears have remained that when deep water is pumped out, contaminated water might filter down to replace it.
Scientists have demonstrated a clear link between the 11-year sun cycle and winter weather over the northern hemisphere for the first time.
Manoa have projected an increased frequency of heavy rainfall events but a decrease in rainfall intensity during the next 30 years (2011-2040) for the southern shoreline of Oahu, according to a recent study published in the Journal of Geophysical Research.
This move will speed the creation of thousands of construction and operations jobs while transforming the nation’s electric system into a modern, 21st century grid that is safer and more secure, and gives consumers more energy choices.
A Californian-based study has looked in detail at air quality and the impact of traffic-related air pollution on premature birth.
Drinking water taken from a deep aquifer protected by a semi-permeable layer of rock should be protected from many contaminants, including viruses. But viruses have been discovered in many deep Madison, Wis., water wells.
Combining recently launched green technology for navigating the oceans with the need to address gaps in critical earthquake information across the globe, scientists from Scripps Institution of Oceanography at UC San Diego have been granted $1.02 million from the National Science Foundation to develop a cutting-edge deep-ocean seismic system.
In the waters along Florida’s east and west coasts, Florida State University (FSU) marine biologists are collecting new data on the once severely overfished Atlantic goliath grouper, a native species that is making a comeback in the southeastern United States after a 21-year moratorium on its capture while remaining critically endangered everywhere else in the world.
Sperm whales are classified as “endangered” under the Endangered Species Act and are listed on Appendix I of the Convention on International Trade in Endangered Species of Wild Fauna and Flora.
The Earth currently has more than 400 so-called "dead zones"--huge expanses of deep ocean that, because of human activities, become too oxygen-starved during the summer to support most life.
An Illinois research team has succeeded in overcoming one major obstacle to a promising technology that simultaneously reduces atmospheric carbon dioxide and produces fuel.
A new research program funded by the National Institutes of Health will explore the role that a changing climate has on human health.
The geologic forces that shape the Earth's surface do their work in the lithosphere, often out of sight and far below the surface. Researchers have now measured the lithosphere’s thickness in southern California. It varies widely, from less than 25 miles to nearly 60 miles.
