Global Warming is "irreversible"

A team of researchers, commissioned by the United States government has come to a conclusion that because of our society’s pollution within the past century, the effects of global warming will not go away for thousands of years!

Take a few minutes and read two separate stories from the BBC and Fox News. Just click on the links below.

    Ive always believed that global warming was mostly human-caused… but now that Fox News is reporting it I cant be too sure….

    I’m skeptical about whether computer models can accurately predict climate change over the course of centuries or millenia. Look at how much trouble we have with computer models that attempt to predict local weather more than 2-3 days off. This does not give me great confidence in the computer models that purport to tell us what global climate changes will occur 300 or 1000 years hence.

    That said… I am also a fairly conservative person when it comes to the environment. If we have to act without full knowledge, which would be the worse error: (1) Behaving as though global warming is not a problem and later finding out that it really is? Or (2) Behaving as though global warming is a problem and finding out later that it really isn’t?

    Personally, I vote for Door #2.

    I’d rather behave as though global warming really is something we need to get serious about preventing, and then at some future date find out (or have future generations find out) that our hearts were in the right place but our reduction of carbon emissions was really unnecessary.

    What is the other choice: Go on producing carbon emissions at the current (or increased) rates, and then later discover, “Uh Oh, Bad Call…” ?

    I’d ask this: if it turns out that we’re wrong in whatever we decide to do, which mistake would you rather have to live with?

    As I said, I think I’d prefer to wrangle the beastie behind door #2.

    I’ll have to dig up the info, but the computer models that determine climate changes (not only future climate change, but how it changed in the past) are inherently different from the ones that predict weather. I don’t recall exactly *how* off the top of my head, though.
