• California coastal infrastructure at risk from rising sea levels

    An exhaustive study by the National research Council finds projects that the sea level off most of California is likely to rise about one meter over the next century, an amount slightly higher than projected for global sea levels; this will place much of the state coastal infrastructure at risk, because significant development along the coast — such as airports, naval air stations, freeways, sports stadiums, and housing developments — has been built only a few feet above the highest tides; for example, the San Francisco International Airport could flood with as little as 40 centimeters of sea-level rise

  • Seeping Arctic methane to pose serious problems for Florida coastline

    Large quantities of methane gas are buried under the Arctic permafrost; the melting of ice caps in the Arctic causes this gas to escape into the atmosphere through vents; until recently, cryosphere (frozen soil and ice) has served to plug or block these vents, but thawing conditions have allowed the conduits to open, and deep geologic methane now escapes; methane is a very strong greenhouse gas, and its presence in the atmosphere has grown three times faster than carbon dioxide since the industrial era

  • Larger role for renewable energy in U.S. future than previously thought

    Renewable electricity generation from technologies that are commercially available today, in combination with a more flexible electric system, is more than adequate to supply 80 percent of total U.S. electricity generation in 2050 while meeting electricity demand on an hourly basis in every region of the country; new study finds that renewable generation could play a more significant role in the U.S. electricity system than previously thought

  • Water for central Everglades essential for reversing ecosystem's decline

    Twelve years into a $13.5billion state and federal effort to save the Florida Everglades, little progress has been made in restoring the core of the ecosystem, says a new congressionally mandated report from the National Research Council; expedited restoration projects that improve the quality and amount of water in this area are necessary to reverse ongoing declines

  • House bill allows Border Patrol to ignore environmental, safety protections along borders

    The House of Representatives passed a sweeping bill which would allow the Border Patrol to ignore dozens of environmental protection laws — among them the Wilderness Act and Endangered Species Act — on all federally managed land within 100 miles of the Mexico and Canada borders; supporters argue that the measure is necessary to give the border patrol more freedom to chase illegal immigrants and drug smugglers; critics charge that the measure has little, if anything, to do with border security, and more to do with opening federally managed land to exploitation by private businesses, or pandering to local political constituencies

  • Carbon capture and storage likely to cause earthquakes

    Carbon capture and storage, or CCS, is a major component of the world’s greenhouse gas reduction strategy; to make a significant contribution to emission reduction, however, CCS would need to operate on a massive scale, potentially sequestering upward of 3.5 billion metric tons of CO2 each year; researchers say that the injection of massive quantities of CO2 would be likely to induce small temblors which would break the reservoirs’ seals and release the stored CO2 into the atmosphere

  • Exploring the Bermuda Triangle's swirling vortices

    Researchers, funded by the Office of Naval Research, deployed twenty-one underwater probes to study vortices at the Bermuda Triangle; a vortex is a swirl of water that can be created in several ways, including water being pushed between land masses and then released into the open ocean; the oceanographers did well to lose only one of the underwater probes, considering they were studying the notorious Triangle

  • For safer offshore drilling, government should modify monitoring practices

    Since the April 2010 Deepwater Horizon blowout and explosion, the federal government as well as the offshore oil and gas industry have been undergoing major changes, including the issuance of regulations requiring operators of offshore facilities to adopt and implement comprehensive Safety and Environmental Management System (SEMS) programs by 15 November 2011

  • Nuclear waste repositories in suburbia?

    Finding sites for nuclear waste storage is a growing problem, with decision makers running into the “not in my back yard” problem; the demise of Nevada’s Yucca Mountain project is but the latest example; researchers find that acceptance of sites for spent nuclear fuel repository may well depend on gender and economic background: in Finland, at least, affluent men more often are more receptive to the idea of locating such facilities near their neighborhoods than women or disadvantaged people

  • Explaining extreme months

    Two months in Midwest history — March 2012 and December 1889 — stand out as the warmest winter months in more than a century of weather records; scientists investigated why these months, separated by 123 years, were so exceptional

  • Laser beams shine light on nature’s extreme events

    “Extreme” events in nature, such as hurricanes, tsunamis and bushfires, may be more commonplace and predictable than you might think; researchers are using lasers to study how frequently extreme events happen, and their work highlights that in nature, “extreme” does not have to mean “rare”

  • Fire risks to increase in some regions of the world

    Climate change is expected to disrupt future fire patterns around the world, with some regions, such as the western United States, seeing more frequent fires within the next thirty years; at the same time, fire activity could actually decrease around equatorial regions, particularly among the tropical rainforests, because of increased rainfall

  • Downstream consequences of depleting groundwater

    Many jurisdictions across the united States manage and regulate surface water and groundwater without any recognition of the connections between the two; for instance, California has no legal framework for comprehensively managing the impacts of groundwater pumping; across most of California, well owners can pump as much as they like with little accountability for the impacts on rivers, other water users and ecosystems

  • Floating dock from Japan carries potential invasive species

    When debris from the 2011 earthquake and tsunami in Japan began making its way toward the West Coast of the United States, there were fears of possible radiation and chemical contamination as well as costly cleanup; a floating dock that unexpectedly washed ashore in Newport, Oregon, earlier this month, and which has been traced back to the Japanese disaster, has brought with it a completely different threat — invasive species

  • Nuclear, coal-fired electrical plants vulnerable to climate change

    Thermoelectric plants, which use nuclear or fossil fuels to heat water into steam that turns a turbine, supply more than 90 percent of U.S. electricity and account for 40 percent of the U.S. freshwater usage; in Europe, these plants supply three-quarters of the electricity and account for about half of the freshwater use; warmer water and reduced river flows in the United States and Europe in recent years have led to reduced production, or temporary shutdown, of several thermoelectric power plants; a new study says this problem will only grow
