Iron From Antarctic Rocks Fuels Algae Growth

MTorrice writes "The Southern Ocean around Antarctica is a significant carbon dioxide sink. Phytoplankton in the ocean pull down a large amount of carbon dioxide from the atmosphere. Oceanographers have wondered where these photosynthetic microbes get enough iron to fuel this process. A new study (abstract) suggests that iron leached into the sea from rock weathering and bacterial activity on Antarctica may be part of the answer. Climate change could actually accelerate this iron release, leading to larger blooms of phytoplankton and more carbon dioxide uptake by the ocean, the researchers say."

    That has to be bullshit because we know climate change is real and man made. The planet is doomed unless everyone rides their bike to work and eats rice cakes.

    I'm sure it will please you to know that your straw man has helped to sequester just a bit of carbon that would otherwise have remained in the atmosphere!

    Does this mean I should cancel my Prius order and go for an Escalade instead?

      Do not worry, fuel prices and energy costs will continue to inflate faster then inflation of fiat currency =) And celebrity boobs.

      You made a good choice!

    But if you burn that straw man, you'll release it back again!

    I saw them a couple of years ago at Ozzfest. They're basically an Iron Maiden / Iced Earth copycat, with the pretentiousness of an 80's hair band but even less talent.
