    Post New Study - Global Warming

    Study says global warming to blame for huge wildfires
    idevb1jm
    COEUR D'ALENE, Idaho (AP) - A study carried out in a central
    Idaho pine forest suggests global warming - not overly thick
    forests - is the leading cause of huge wildfires that have been
    burning in the West every season for nearly 20 years.
    The findings are published in the latest issue of the journal
    Nature.
    The study analyzed 8,000 years of sediment accumulated in the
    valley of the South Fork Payette River near Lowman, where records
    of massive, prehistoric wildfires are buried in the sediment.
    After the fires, rain and snowmelt flowed over a floor sealed by
    the heat and ash, creating a cement-like slurry of charcoal,
    boulders and bits of trees. The most severe fires caused the
    thickest bands of sediment.
    Most fire history is based on studying tree rings and typically
    extends back no further than 500 years, the age of the oldest
    ponderosa pines, said Grant A. Meyer, co-author of the study and
    associate professor of earth and planetary sciences at the
    University of New Mexico.
    The period from about 1350 to the beginning of the 20th century
    was known as the Little Ice Age. Rocky Mountain glaciers grew
    larger during this period. And the wet, cool conditions allowed
    grasses to flourish on forest floors, which provided tinder for
    frequent but cool ground fires.
    Foresters see this time as a period when cool fires and old
    trees seemed to be in harmony, Meyer said. However, the time before
    the Little Ice Age probably provides a more accurate glimpse of the
    interplay between forests and fire.
    Before the Little Ice Age was a 400-year period of hot, dry
    weather with multiple, decades-long droughts, Meyer said. Several
    massive wildfires burned the forest to the ground above the Payette
    River.
    "The fires must have been quite severe," Meyer said.
    It appears that temperatures today are even higher than they
    were during the medieval period, the scientists wrote.
    Most scientists believe the current warming trend is the result
    of a buildup of greenhouse gases, such as carbon dioxide, caused by
    the burning of coal, oil and other fossil fuels.
    Fire had always been allowed to rid the forest floor of excess
    fuel, yet this did not protect the forest from large-scale
    destruction by fire during the warming trends, said Jennifer
    Pierce, a University of New Mexico graduate student and lead author
    of the study.
    This may mean that forests cannot be protected by thinning
    projects, because historical evidence shows that fires will only be
    hotter and larger on a planet that continues to heat up, Pierce
    said.
    "Management policy needs to incorporate climate change, instead
    of trying to get back to these Little Ice Age conditions where
    fires were small," Pierce said. "That's just not realistic.
    Maintenance of those conditions will be difficult in the face of
    global warming."
    Retired U.S. Forest Service fire ecologist Stephen Arno said
    climate should not be ignored, but forest thinning remains the best
    defense against catastrophic wildfire.
    Recent years have provided "innumerable examples" where
    thinned forests have slowed the rapid spread of forest crown fires,
    said Arno, author of the 1999 book "Flames in Our Forest."
    "Fuels management can work to mitigate the severity of fires.
    Even with climate change, you're still going to need to control
    fuel buildup," he said.

    So scientific examination of soil samples SUGGEST that local or global heating/cooling cycles have been a regular occurance - a theory. Reason for change, if it actually has occured was for some unknown reason. Interject theory on why such cycles have occured. Interesting science. Might well be correct as a locical case that things change over time. Can theorize for years if correct and WHY might have occured.

    Now shift gears to political agenda and determine that the current, THEORETICAL, cooling cycle, for the 1st time, in history is caused by the actions of man. HUHHHH?
