Bioenergy From Cleared Forests A Climate Killer

And last fall, the National Acadamies – consisting of the National Academy of Sciences, National Academy of Engineering, Institute of Medicine, and National Research Council – reported that U.S. policy incentivizing biofuels production may be an ineffective in reducing global greenhouse gas emissions, and that it could have mixed economic and environmental effects. The environmental impacts of bio-based fuels are highly dependent on site-specific factors, such as the types of feedstocks and management practices for land and water use. While biofuels production has been shown to have both positive and negative effects on water quality, soil, and biodiversity; air-quality modeling suggests that the production and use of ethanol is likely to increase air pollutants such as particulate matter, ozone and sulfur oxides.

This new research could be yet another blow against against plant-based fuels, UC Davis suggests.

“The study’s findings have potential implications for biofuel incentives based on greenhouse gas emissions,” says the UC Davis statement. “For instance, if the United States decides to incentivize corn-based ethanol, less profitable crops, such as soybeans, may shift to other countries. And those countries might clear more forests to make way for the new crops. Where those countries are located and how the wood from those forests is used would affect how much carbon would be released into the atmosphere.”

    Q: Was climate change a catastrophic end for all
    or just an exciting research opportunity?

    A: It was a consultant’s wet dream of some worst
    case scenario research of the effects (almost never the causes), of an assumed
    to be real crisis and the crisis couldn’t be proven or disproved anyways.

    Q: How many climate change scientists does it
    take to change a light bulb?

    Q: None, but they do have full consensus that it
    WILL change.

    Q: How do we stop heating of the planet?

    A: Easy! We tax the air we breathe with taxes
    from bank funded and corporate run carbon trading stock markets ruled by politicians
    and we let Liberal Dems control the temperature of the planet and tame the wild
    weather.

    Q: What is that the world of science agrees on
    with climate change?

    A: They *agree the effects from Human CO2 on the
    climate will be negligible to unstoppable heating of the entire planet Earth.

    *They all agree AGW is real while very few call
    climate change a deadly crisis but lazy copy and paste news editors will print
    anything.
