New Billboard Clocks Carbon Emissions

First the debt clock, then that crazy time piece in union square, and now NYC is home to the carbon emissions clock.  Interesting idea, but i agree with the guy in the report that most people wont know what the hell it means.  money is easy to understand, lbs of carbon - not so much.  how much is too much? what are the lethal levels?  how much time do we have? a lot of questions to answer when someone is looking out the window of a speeding cab.
