Berkeley Lab News Center » IMPACTS: On the Threshold of Abrupt Climate Changes - 0 views

  •  
    Abrupt climate change is a potential menace that hasn't received much attention. That's about to change. Through its Climate Change Prediction Program, the U.S. Department of Energy's Office of Biological and Environmental Research (OBER) recently launched IMPACTS - Investigation of the Magnitudes and Probabilities of Abrupt Climate Transitions - a program led by William Collins of Berkeley Lab's Earth Sciences Division (ESD) that brings together six national laboratories to attack the problem of abrupt climate change, or ACC.

Key New Ingredient In Climate Model - Environment - an eLab Article at Scientist Live - 0 views

  •  
    For the first time, climate scientists from across the country have successfully incorporated the nitrogen cycle into global simulations for climate change, questioning previous assumptions regarding carbon feedback and potentially helping to refine model forecasts about global warming. The results of the experiment at the Department of Energy's Oak Ridge National Laboratory and at the National Center for Atmospheric Research are published in the current issue of Biogeosciences. They illustrate the complexity of climate modeling by demonstrating how natural processes still have a strong effect on the carbon cycle and climate simulations. In this case, scientists found that the rate of climate change over the next century could be higher than previously anticipated when the requirement of plant nutrients are included in the climate model. ORNL's Peter Thornton, lead author of the paper, describes the inclusion of these processes as a necessary step to improve the accuracy of climate change assessments.

CLIMATE CHANGE: 100-Percent Renewables Not a Pipe Dream - 0 views

  •  
    KINGSTON, Ontario, Jun 25 (IPS) - North America's abject failure to meet the challenge of climate change has been "un-American", environmentalist and scientist David Suzuki told delegates Tuesday at the World Wind Energy Conference, the first ever in the region. "We're facing an ecological crisis, a crisis far, far worse than Pearl Harbour," Suzuki said. Twenty years ago this week, one of the United States' leading scientists warned Congress of the imminent danger of climate change and said that waiting decades to take action was too risky. Now James E. Hansen of the National Aeronautics and Space Administration has published new research indicating that greenhouse gas concentrations have pushed the climate near a dangerous tipping point that will unleash far-reaching changes in the atmosphere and oceans that could take millennia to reverse.

Costs of climate change, state-by-state: Billions... ( Climate change will carry a pric... - 0 views

  •  
    Climate change will carry a price tag of billions of dollars for a number of U.S. states, says a new series of reports from the University of Maryland's Center for Integrative Environmental Research (CIER). The researchers conclude that the costs have already begun to accrue and are likely to endure. Combining existing data with new analysis, the eight studies project the long term economic impact of climate change on Colorado, Georgia, Kansas, Illinois, Michigan, Nevada, New Jersey and Ohio. Studies on additional states are in the works.

Peak Energy: Better Wind Turbines - 0 views

  •  
    Technology Review has an article on advances in wind turbine technology - Better Wind Turbines. ExRo Technologies, a startup based in Vancouver, BC, has developed a new kind of generator that's well suited to harvesting energy from wind. It could lower the cost of wind turbines while increasing their power output by 50 percent. The new generator runs efficiently over a wider range of conditions than conventional generators do. When the shaft running through an ordinary generator is turning at the optimal rate, more than 90 percent of its energy can be converted into electricity. But if it speeds up or slows down, the generator's efficiency drops dramatically. This isn't a problem in conventional power plants, where the turbines turn at a steady rate, fed by a constant supply of energy from coal or some other fuel. But wind speed can vary wildly. Turbine blades that change pitch to catch more or less wind can help, as can transmissions that mediate between the spinning blades and the generator shaft. But transmissions add both manufacturing and maintenance costs, and there's a limit to how much changing the blade angle can compensate for changing winds.

The Associated Press: Cheney reportedly wanted cuts in climate testimony - 0 views

  •  
    Vice President Dick Cheney's office pushed for major deletions in congressional testimony on the public health consequences of climate change, fearing the presentation by a leading health official might make it harder to avoid regulating greenhouse gases, a former EPA officials maintains. When six pages were cut from testimony on climate change and public health by the head of the Centers for Disease Control and Prevention last October, the White House insisted the changes were made because of reservations raised by White House advisers about the accuracy of the science.

Government Accountability Project: EPA Quietly Releases Climate Change Health Effects R... - 0 views

  •  
    Today, the Environmental Protection Agency (EPA) released a major study by the US Climate Change Science Program synthesizing current scientific knowledge of climate change-induced threats to human health. This information should be critical to the EPA's previous "endangerment finding" for carbon dioxide and other greenhouse gases. However, the EPA Office of Air and Radiation, the branch assigned rulemaking responsibility, evidently did not rely on and did not cite the CCSP report.

The Cost of Energy » Document alert: Global Wind Energy Outlook 2008 - 0 views

  •  
    New Study: 10 billion tonne saving in CO2 possible with wind energy by 2020: Wind power is key technology to prevent dangerous climate change. Wind power could produce 12% of the world's energy needs and save 10 billion tones of CO2 within 12 years, according to a new report published today. The 'Global Wind Energy Outlook 2008', published by the Global Wind Energy Council (GWEC) and Greenpeace International, looks at the global potential of wind power up to 2050 and found that it could play a key part in achieving a decline in emissions by 2020, which the IPCC indicates is necessary to avoid the worst consequences of climate change.7By 2020, wind power could save as much as 1.5 billion tonnes of CO2 every year, which would add up to over 10 billion tonnes in this timeframe. The report also explains how wind energy can provide up to 30% of the world's electricity by the middle of the century.

What's hot on energy policy's to-do list? - Frank N. Carlson - Medill News Service - Po... - 0 views

  •  
    What does "energy policy" mean to you? Does it conjure up questions of national security and terrorism? Or is it more about promoting cheap, renewable fuels? Maybe your take is about climate change and reducing greenhouse gases? Despite the various interpretations of the issue, or perhaps because of them, energy policy ranked high on the priority lists of voters of both parties on Nov. 4. Much of the interest can be attributed to the record run-up in oil and gasoline prices earlier in the year, which have since fallen off by about half, but increased awareness of climate change also played a big role.
