    Exactly how much of the greenhouse gas carbon dioxide is siphoned from the atmosphere each year by various biological and geological processes? Unlike the value of Enron stock, this carbon does not vaporize. Instead, it sloshes around the planet in the so-called carbon cycle.

    Eventually, carbon is returned to the atmosphere, which contains roughly 750 gigatons (billion tons) of the stuff, in the form of carbon dioxide. But the delay time can be weeks (about as long as it took Enron to crash and burn) -- or millions of years.

    About 5 gigatons of carbon enters the atmosphere each year from burning fossil fuels, deforestation and other human causes. Some of that is incorporated into vegetation, dissolved in the ocean, or solidified into sedimentary rock. A key question is how long the carbon stays bound up before returning to the atmosphere.

    Budgetary imbalance
    In recent years, some scientists have argued that large amounts of carbon dioxide get trapped in vegetation, especially wood. They looked at forests -- both temperate and tropical -- as one of the biggest so-called "sinks."

    But the world is a big place, and there are plenty of questions about how much carbon should actually be listed on the account books of Earth's various habitats. To document the movement of carbon dioxide, Jeffrey Richey, a professor of oceanography at the University of Washington, and colleagues took 1,800 samples in the Central Amazon basin, a huge potential sink for atmospheric carbon.
