Thread: Source of Global warming gas found!!

  1. #1
    German scientists have discovered a new source of methane, a greenhouse gas that is second only to carbon dioxide in its impact on climate change.
    The culprits are plants.
    They produce about 10 to 30 percent of the annual methane found in the atmosphere, according to researchers at the Max-Planck Institute for Nuclear Physics in Heidelberg, Germany.
    The scientists measured the amount of methane released by plants in controlled experiments. They found it increases with rising temperatures and exposure to sunlight.
    "Significant methane emissions from both intact plants and detached leaves were observed ... in the laboratory and in the field," Dr Frank Keppler and his team said in a report in the journal Nature.
    Methane, which is produced by city rubbish dumps, coal mining, flatulent animals, flatulent Hot boat Forum Members,rice cultivation and peat bogs, is one of the most potent greenhouse gases in terms of its ability to trap heat.
    Concentrations of the gas in the atmosphere have almost tripled in the last 150 years. About 600 million tonnes worldwide are produced annually.
    The scientists said their finding is important for understanding the link between global warming and a rise in greenhouse gases.
    It could also have implications for the Kyoto Protocol, which calls for developed countries to cut their emissions of greenhouse gases by 5.2 percent below 1990 levels by 2008-12.
    Keppler and his colleagues discovered that living plants emit 10 to 100 times more methane than dead plants.
    Scientists had previously thought that plants could only emit methane in the absence of oxygen.
    David Lowe, of the National Institute of Water and Atmospheric Research in New Zealand, said the findings are startling and controversial.
    "Keppler and colleagues' finding helps to account for observations from space of incredibly large plumes of methane above tropical forests," he said in a commentary on the research.
    But the study also poses questions, such as how such a potentially large source of methane could have been overlooked and how plants produced it.
    "There will be a lively scramble among researchers for the answers to these and other questions," Lowe added.

    Therefore all the treehuggin fuggers crying "save the rain forest" are the cause of global warming.

    I heard that the increased forestation caused it... It seems that the dark green color of the leaves capture more of the sun's heat and don't reflect it like the deserts do.... And the environuts are putting more solar panels in the desert, trapping even more heat, contributing further to global warming....
    We are doomed, DOOMED, DOOMED, I tell you!! :crossx:

    Seems like it would be old news that plants produced methane. About as pertinent to anything as the theory a couple years back that pig farms in the SE were major methane contributors to global warming.
    The media jumps on more junk science taken out of context is most likely scenario.
    I wonder what they'll say about the Alaska Volcano going off this week? Volcanic eruptions contribute more bad gases to the atmosphere than all manmade contributions combined, but these facts are always backpage news.
