• The Western hemisphere’s largest seawater desalination plant to be built in California

    The San Diego County Water Authority announced plans to build the Western hemisphere’s largest seawater desalination plant; the plant will produce fifty million gallons of fresh water per day, enough to supply about 7 percent of the San Diego region in 2020

  • New study tracks long-term sea-level rise

    Greenhouse gas emissions up to now have triggered an irreversible warming of the Earth which will cause sea-levels to rise for thousands of years to come, new research has shown; mankind has already committed itself to a sea-level rise of 1.1 meters by the year 3000 as a result of greenhouse gas emissions up to now; this irreversible damage could be worse, depending on the route we take to mitigating emissions

  • Explosives dumped into Gulf of Mexico pose big problems

    Millions of pounds of unexploded bombs and other military ordnance that were dumped decades ago in the Gulf of Mexico, as well as off the coasts of both the Atlantic and Pacific oceans, could now pose serious threats to shipping lanes and the 4,000 oil and gas rigs in the Gulf, warns two oceanographers

  • Helping improve microbes’ ability to remediate toxic metal contamination

    Naturally occurring bacteria in the Gulf of Mexico did a great job helping to clean up 2010’s huge Deepwater Horizon oil spill, but bacteria can do even heavier lifting; routinely used to help clean up toxic metals at contaminated sites, bacteria and other soil microbes are fed to boost their ability to turn soluble metals into solids that will not leech into streams or aquifers

  • More ways to combat water shortages

    Water is the one element that every breathing, living organism on Earth needs, and unlike oil, there are no viable alternatives; in many undeveloped countries, water is becoming scarce. Concerns are growing about the availability of water in developed countries as well

  • Chile relies on new technologies to cope with frequent earthquakes

    Citizens of Chile are used to the ground shaking beneath their feet; in the past two years alone Chile has experienced more than forty earthquakes with magnitudes of six or higher; with so many earthquakes and the potential of thousands dying yearly, Chilean authorities are using new methods to protect their citizens from death and buildings from damage

  • Hurricane Irene polluted Catskills watershed

    The water quality of lakes and coastal systems will be altered if  hurricanes intensify in a warming world, according to a Yale study; researchers found that last summer during Hurricane Irene — the worst storm in the New York area in 200 years — record amounts of dissolved organic matter darkened Catskill waters and affected the Ashokan Reservoir that supplies New York City with drinking water

  • Large 11 April 2012 earthquake triggered temblors worldwide for a week

    This year’s largest earthquake, a magnitude 8.6 temblor on 11 April centered in the East Indian Ocean off Sumatra, did little damage, but it triggered quakes around the world for at least a week; the findings are a warning to those living in seismically active regions worldwide that the risk from a large earthquake could persist — even on the opposite side of the globe — for more than a few hours

  • Debate over causes of levee failure during Katrina intensifies

    A court case in which residents of two sections of New Orleans are suing a construction group has put millions of dollars at stake; residents of the Lower 9th Ward and St. Bernard Parish residents claim that Washington Group International (WGI), an Amy Corps of Engineers contractor, removed several buildings and pilings from land along the Industrial Canal as part of a construction plan to expand the canal’s shipping lock, then failed adequately to plug the holes left behind; the holes allowed rainwater from Hurricane Katrina to seep underneath the 14-foot wall, essentially lifting the wall and allowing the areas to be flooded

  • Keystone XL pipeline: reliability of remote oil-spill sensors questioned

    The oil industry plans to build thousands of miles of pipelines in the next five years, making leak detection a growing issue; many of the new pipelines will cross aquifers and rivers which are used for drinking water and irrigation; the Keystone XL pipeline has already experienced its share of controversies, and now there is a debate over the quality and reliability of the pipeline’s sensor system for remote detection of oil spills

  • Desalination losing ground as a solution to California’s chronic water shortage

    According to the July 2011 census, more than thirty-seven million people live in California, increasing the pressure on the state’s water sources; desalinating sea water as a solution to the scarcity of fresh water is not a new technology — it has been around for more than four decades — but it has more recently been considered as a way to address California’s chronic, and growing, water shortage; a closer examination of the technology and its cost has cooled the initial enthusiasm for it

  • Harvesting fuel for the fleet from seawater

    Refueling U.S. Navy vessels, at sea and underway, is a costly endeavor in terms of logistics, time, fiscal constraints, and threats to national security and sailors at sea; in Fiscal Year 2011, the U.S. Navy Military Sea Lift Command, the primary supplier of fuel and oil to the U.S. Navy fleet, delivered nearly 600 million gallons of fuel to Navy vessels underway, operating fifteen fleet replenishment oilers around the globe; the Naval Research Laboratory believes there is a better way: extracting carbon dioxide (CO2) and producing hydrogen gas (H2) from seawater and then catalytically converting the CO2 and H2 into jet fuel

  • Exploring solutions to growing water shortages

    Most Americans do not pay much attention to how much water they use when they take a shower or when they water the grass, but Michael Sullivan, a global executive at IBM thinks this will change; “Water is a finite resource,” Sullivan told a panel in a conference on water policy; “What we’re dealing with is that there’s a finite supply, and as the population grows and industry grows, we’re stressing that finite supply”

  • New York unprepared for flooding, sea level rise

    New York City may be a fast paced city of bright lights, sleek attitudes, fashion trends, and some of the best sports teams in the country, but underneath the glitz and glamour is a city which is not prepared for an act of God and which is being threatened by rising sea levels and severe storm flooding; “It’s a million small changes that need to happen,” one expert says

  • Limiting world trade unlikely to reduce CO2 emissions

    The United States emits less CO2 in the production of its exports than is contained in its imports, simply because it imports more than it exports; only about 20 percent of CO2 transfers from China into the United States can be traced back to the fact that China is in effect relatively more specialized in the production of dirty goods; interventions in world trade, like CO2 tariffs, would probably have only a small impact on global emissions
