  • Climate Ecosystems Reference Ocean current Atmospheric circulation Gulf Stream Mid-ocean ridge In a paper in the June 18 issue of Science, a Duke University oceanographer reviews the growing body of evidence that suggests it's time to rethink the conveyor belt model.

    "The old model is no longer valid for the ocean's overturning, not because it's a gross simplification, but because it ignores crucial elements such as eddies and the wind field. The concept of a conveyor belt for the overturning was developed decades ago, before oceanographers had measured the eddy field of the ocean and before they understood how energy from the wind impacts the overturning,"

    "climate policy-makers need to pay much more attention to restricting short-lived pollutants, such as methane, carbon monoxide, volatile organic compounds (VOCs) and aerosols. This could create significant changes in the local and global climate quite quickly, whereas the effects of efforts to reduce emissions of long-lived carbon dioxide will not be seen for many years."

    These conclusions come too late to have a real impact on decisions that will be taken in Copenhagen, I assume. But I think it is a hot topic as climate change 'solutions' that work QUICKLY are more and more needed!!

    "But researchers say what's good for ozone is bad for climate change. In the atmosphere, these replacement chemicals [replacements for CFCs] act like "super" greenhouse gases, with a heat-trapping power that can be 4,470 times that of carbon dioxide." Havent't heard of this before...

  • Therefore, the American Meteorological Society recommends:
  • Enhanced research on the scientific and technological potential for geoengineering
  • the climate system, including research on intended and unintended environmental responses.
  • ...2 more annotations...
  • Coordinated study of historical, ethical, legal, and social implications of geoengineering
  • that integrates international, interdisciplinary, and intergenerational issues and perspectives and includes lessons from past efforts to modify weather and climate. Development and analysis of policy options to promote transparency and international cooperation in exploring geoengineering options along with restrictions on reckless efforts to manipulate the climate system.
