• Border security bill would harm U.S. National Parks: environmentalists

    A bill pending in the U.S. House of Representatives would suspend the enforcement of almost all the U.S. environmental laws on all lands under the jurisdiction of the Departments of the Interior and Agriculture within 100 miles of the northern border with Canada and the southern border with Mexico; the 100-mile zone includes fifteen National Parks which cover 21,657,399 acres, or nearly 25 percent of the overall footprint U.S. National Park System; supporters of the bill claim it would bolster border security, while environmentalists say it would gut a century’s worth of proven federal lands protection

  • Scientists: Deepwater Horizon exposed gaps in deepwater oil spill knowledge

    On the second anniversary of the Deepwater Horizon oil spill in the Gulf of Mexico, a national team of scientists warns that inadequate knowledge about the effects of deepwater oil well blowouts threatens scientists’ ability to help manage comparable future events

  • Solar storms and infrastructure vulnerabilities

    Space weather, and in particular coronal mass ejections, can cause huge disruption to many highly technological systems on Earth; experts say that vulnerable industries, such as power grids and airlines, should gather more information on space weather in order to make more informed decisions about how to deal with future solar storms

  • Himalayan glaciers decline less rapidly than previously feared

    Several hundreds of millions of people in Southeast Asia depend, to varying degrees, on the freshwater reservoirs of the Himalayan glaciers; it is thus important to detect the potential impact of climate changes on the Himalayan glaciers at an early stage; together with international researchers, glaciologists from the University of Zurich now show that the glaciers in the Himalayas are declining less rapidly than was previously thought; the scientists, however, see major hazard potential from outbursts of glacial lakes

  • Autonomous, self-replicating robots for finding extraterrestrials

    Autonomous, self-replicating robots — exobots — are the way to explore the universe, find and identify extraterrestrial life, and perhaps clean up space debris in the process; scientists note that if aliens are out there, they have the same problems we do: they need to conserve resources, are limited by the laws of physics, and they may not even be eager to meet us

  • Water vulnerability in U.S. border region

    The Arizona-Sonora region has been called the front line of ongoing climate change, with global climate models projecting severe precipitation decreases and temperature increases coupled with vulnerability from urbanization, industrialization and agricultural intensification

  • Robust nanosponges soak up oil again and again

    Researchers show that nanotube blocks hold promise for environmental cleanup following oil spills or other disasters; the robust sponge can be used repeatedly and stands up to abuse; a sample nanosponge remained elastic after about 10,000 compressions in the lab; the sponge can also store the oil for later retrieval

  • Ion stream to clean up Earth orbit, deflect asteroids

    One of the legacies of the space age is an ever-more-crowded near-Earth orbit, where all manner of long-abandoned human-made objects loiter, posing danger to newer space platforms; scientists want to develop a magnetized-beam plasma propulsion device which would be deployed in Earth orbit and which would  use a focused ion stream to push dead satellites and other debris toward Earth’s atmosphere, where they would mostly burn up on re-entry; the device could also be used to deflect menacing Earth-bound asteroids hurtling toward Earth

  • Diet change required to curb most potent greenhouse gas

    N2O is the third highest contributor to climate change behind carbon dioxide (CO2) and methane (CH4), but it poses a greater challenge to mitigate as nitrogen is an essential element for food production; it is also the most potent of these three greenhouse gases as it is a much better absorber of infrared radiation

  • In environmental disasters, families experience conflict, denial, silence

    Environmental disasters affect individuals and communities; they also affect how family members communicate with each other, sometimes in surprising ways; the researchers say that the findings were, in some ways, counterintuitive

  • Southern sea levels rise dramatically

    Sea levels have risen about twenty centimeters in the South West Pacific since the late nineteenth century, a new scientific study shows

  • Most states in U.S. unprepared for growing water threats to economy, health

    Only nine states in the United States have taken comprehensive steps to address their vulnerabilities to the water-related consequences of changes in climate — rainfall events which increase flooding risks to property and health change, and drought conditions which threaten supply for municipalities, agriculture, and industries — while twenty-nine states are unprepared for growing water threats to their economies and public health

  • Miniature sensors to advance climate studies, battlefield detection

    Self-sealing valves are not only better for collecting reliable climate information – they also increase data reliability for airborne industrial and battlefield gas detection and point-of-contact medicine

  • Stormy weather in Europe's future

    Europeis likely to be hit by more violent winter storms in the future; a new study into the effects of climate change has found out why

  • U.S. Navy experience shows climate alterations

    The U.S. Navy reports that because of its worldwide presence, it sees the effects of climate change directly; and expert tells a scientific audience at Sandia Lab that disparities in current climate science projections “mean that the Navy should plan for a range of contingencies, given our limited ability to predict abrupt change or tipping points for potentially irreversible change”
