• Climate change threatens Canada North's infrastructure

    Climate change is felt more acutely in the arctic, and a Canadian government’s report says that winter roads melting earlier in the spring could force communities to airlift supplies, while increased snowfall and changing ice conditions can add stress to buildings as well as energy and communications infrastructure

  • Climate change will lead to more wars and deaths in Africa

    Researchers predict that spikes in temperature will lead to a 54 percent rise in the incidence of civil conflict in Africa by 2030, resulting in an extra 393,000 combat deaths;

  • Dutch build sand dunes to fight rising seas

    More than eighteen million cubic meters of sand are dredged from the bottom of the ocean and brought back to land to form new dunes; the new dunes — each 30 to 60 meters wide, and rising up to 10 meters above sea level — are built along a 20-kilometer stretch of the shore

  • Los Alamos lab's toxic waste seeps toward New Mexico's water sources

    Radioactive debris has been found in canyons that drain into the Rio Grande, but officials at the Los Alamos National Laboratory say there is no health risk; to comply with New Mexico’s clean up orders, the lab has installed about 300 monitoring wells and gauges, contaminated soil is being removed from canyon bottoms, wetlands are being planted, and small dams built to arrest the flow of polluted storm water

  • U.S. Congress holds hearings on geoengineering

    Geoengineering — the effort to design systems which would change the world’s climate — was once a fringe phenomenon; it has been moving into the mainstream, though, as more and more scientists are growing increasingly concerned that, even if we commit to cutting emissions drastically, we have already waited too long, and that by the time we actually reduce emissions, enough greenhouse gases will have accumulated to cause serious climate disasters

  • Using technology to prepare vulnerable communities for earthquakes

    Satellite photographs and remotely measured surface heights from NASA will be used for assessing the vulnerability of natural slopes to earthquake-induced landslides; a team of U.K. scientists will also build up a database of slopes that failed in earthquakes; the information collected will include local geology, vegetation, slope angle, distance from the fault, and the amount of ground shaking

  • African desert rift confirmed as new ocean is forming

    Geologists show that seafloor dynamics are at work in splitting African continent; scientists from several countries have confirmed that the volcanic processes at work beneath the Ethiopian rift are nearly identical to those at the bottom of the world’s oceans, and the rift is indeed likely the beginning of a new sea

  • Nuclear energy central to climate debate

    There are 104 power reactors in 31 states, providing one-fifth of the U.S. electricity; they are also producing 70 percent of essentially carbon-free power and are devoid of greenhouse gas emissions; a study by the industry-supported Electric Power Research Institute says 45 new reactors are needed by 2030; the Energy Information Administration puts the number at 70; an analysis by the Environmental Protection Agency (EPA) assumes 180 new reactors by 2050 for an 80 percent decline in greenhouse gas emissions

  • Louisiana levee to use stabilizing fabric

    The 1,600-foot earthen levee, which runs south from the Old Estelle Pump Station, has failed twice, once in the early 1990s and again in 2007 when two sections totaling 600 feet long slumped badly; Army Corps of Engineers will use geotextile fabric to stabilize known trouble spots before raising the levee from 10 feet to 14.5 feet

  • Despite concerns, development still heads to the coast

    Many scientists predict that by 2100, sea levels would rise more than one meter; still, Florida has opened more vulnerable areas along the Atlantic coast to construction — and has done so more than any other state

  • Aussies worry about rising sea levels

    About 80 percent of Australians live in coastal areas, and a new parliamentary report recommends new laws banning further development in coastal regions

  • A new Amsterdam neighborhood floats on a lake

    The Dutch experiment with a new concept for addressing over-crowding, flooding, and rising sea-level problems: floating neighborhoods

  • Cosmic entropy could be 100 times greater than previously thought

    Entropy increases as the number of ways the system can be arranged microscopically without changing the external appearance increases; new study shows that cosmic entropy is a 100 times greater than earlier estimates; the entropy of the universe must be below the maximum theoretical value or life and other complex phenomena will cease to exist; as the entropy gradually increases it will eventually approach the theoretical maximum, a state many physicists have called the heat death of the universe; the new study thus shows that our universe is closer to its death than previously thought

  • Tornado threat increases as Gulf hurricanes get larger

    New study predicted exactly the number of hurricanes seen for Hurricane Ike: 33; tornadoes that occur from hurricanes moving inland from the Gulf Coast are increasing in frequency

  • Without water reform Asia will face food shortage by 2050

    There are three options for meeting the food needs of Asia’s population, which will expand by one-and-a-half billion people over the next forty years: The first is to import large quantities of cereals from other regions; the second to improve and expand rainfed agriculture; and the third to focus on irrigated farmlands
