• The good news: Tests confirm oil is light grade

    Preliminary tests on the oil spilled in the Gulf show that the material is typical Louisiana sweet crude, a light oil that can be either burned or readily dispersed; scientists were alarmed Friday when one of the samples showed a higher-than-expected concentration of asphalt and other nonvolatile components; such materials are extremely resistant to degradation, and they also are resistant to burning and extremely difficult to clean up once they reach the shore; scientists now believe the Friday samples were contaminated

  • Gulf oil spill exposes industry's lack of readiness, preparation

    The oil spill in the Gulf will inevitably become the worst spill in U.S. history — if it is not the worst already; BP has begun a three-month project to drill a relief well in 5,000ft of water to intercept and isolate the existing well at around 13,000ft below the seabed; one expert says: “At 1,500m the head is as easy to get to as if it were on the moon”

  • Texas A&M scientist tracks origins of bootleg honey from China

    The United States has imposed a 500 percent tariff on honey from China two years ago because the Chinese government is subsidizing Chinese honey makers so they can drive U.S. producers out of the market; the practice has almost ruined the market for domestic U.S. honey; China is trying to get around the anti-dumping measure by putting labels such as “Product of Thailand” or “Product of Indonesia” on Chinese honey; a Texas A&M honey specialist stands in their way by doing melissopalynology — the study of pollen in honey

  • Gulf of Mexico oil reaches coast; White House calls spill event of "national significance"

    Gulf oil spill reaches Louisiana shore; cost of clean up is estimated at $8 billion; DHS secretary Napolitano declares the spill an event of “national significance,” opening the door for increased federal involvement; Louisiana declares state of emergency

  • A first: Engineers build giant dome to contain Golf oil spill

    Engineers have began to construct a giant dome over a large oil spill in the Gulf of Mexico; the dome would capture or gather the oil and allow it to be pumped out of that dome structure; the dome would be similar to welded steel containment structures called cofferdams used in oil rig construction, but it would be an original design never fabricated or tested before

  • Coast guard my use controlled burn for Gulf oil spill

    A large oil spill from a rig in the Gulf of Mexico is threatening vital ecological areas along the Louisiana shore; DHS and the Coast Guard are considering a controlled burn of the menacing oil spill; controlled burns have been done and tested before

  • Indonesia to tap volcano power

    Indonesia is a country of 17,000 islands; the archipelago contains 265 volcanoes, estimated to hold around 40 percent of the world’s geothermal energy potential; investors, the World Bank, and the Indonesian government embark on an ambitious plan to add 4,000 megawatts of geothermal capacity — up from the existing 1,189 megawatts — by 2014, and 9,500 megawatts by 2025, by tapping the volcanoes

  • Federal loans notwithstanding, Georgia nuclear power plant faces hurdles

    The Obama administration has signaled its interest in expanding the U.S. domestic nuclear power industry by giving $8.3 billion in loan guarantees for a Georgia nuclear power plant expansion; critics say that the American tax-payer is at risk; that the original nuclear reactor design has been rejected by the NRC, and that there is no solution for the nuclear waste problem

  • Cold war offered odd benefit: it limited species invasions

    During the cold war, when an Iron Curtain divided the European continent, there were few introduced bird species in Western Europe; following the collapse of the Soviet Union and the removal of the Iron Curtain, trade and the movement of people between east and west increased – and with it the introduction of non-native bird species; these non-native species do not have natural enemies in the local habitat, so they do damage to agriculture and domestic birds, and carry disease

  • Climate change experts argue for international geoengineering effort

    Solar-radiation management (SRM) would involve releasing megatons of light-scattering aerosol particles in the upper atmosphere to reduce Earth’s absorption of solar energy, thereby cooling the planet; another technique would be to release particles of sea salt to make low-altitude clouds reflect more solar energy back into space; long-established estimates show that SRM could offset this century’s predicted global average temperature rise more than 100 times more cheaply than achieving the same cooling by cutting emissions

  • Experts: U.K. must act now to prepare for rising sea level

    A joint study by the leading U.K. civil engineering and architectural associations says that steps must be taken now to protect coastal towns from rising sea levels; the reports says policy makes should consider three options for tackling rising sea level: “retreat” — moving critical infrastructure and housing to safer ground; “defend” — building town or city-wide sea defenses; and “attack” — extending the existing coastline and building out on to the water

  • Maximum height of extreme waves up dramatically in Pacific Northwest

    A new assessment concludes that the highest waves in a “100-year event” along the Pacific Northwest’s coast may be as much as 46 feet, up from estimates of only 33 feet that were made as recently as 1996, and a 40 percent increase; the new findings raise special concerns for flooding, coastal erosion, and structural damage; “The Pacific Northwest has one of the strongest wave climates in the world, and the data clearly show that it’s getting even bigger,” says one of scientists involved

  • Large dams linked to more extreme weather patterns

    A new study looked at the magnitude of the biggest storms near 633 of the world’s largest dams before and after construction; they found that in many places the level of precipitation in the most extreme rainfall events grew by an average of 4 percent per year after a dam was built, with the relationship especially strong in semi-arid regions

  • Scientists seek homes in the Seattle area in which to install quake monitors

    Scientists want to install seismic monitors in homes in the Seattle area to measure ground-shaking; with detailed information on the way the ground shakes in a particular spot, it may be possible to design buildings tailored to their exact locations; the instruments also will help construct “shake-maps” to pinpoint areas of heaviest damage after major earthquakes

  • Rise in sea levels forces drastic changes on Florida

    If sea levels rise by only two feet, Florida stands to lose almost 10 percent of its land area and the homes of 1.5 million people; the zone which is vulnerable to 27-inch rise in sea level includes residential real estate worth $130 billion, half of Florida’s beaches, two nuclear reactors, three prisons, 37 nursing homes, and much more; the Florida government is considering changes to building codes and other precautionary measures.
