    Somebody told me, that drilled ice cores show that the concentration of CO2 in the atmosphere around the beginning of the industrial revolution was 280ppm. Today, what with increased consumption of fossil fuels, the number is 400ppm.
    I've also been told, that a number above 600ppm CO2 in a work place without proper ventilation will start to give you coordination and concentration issues.
    And I've also been told, that if we continue to consume fossil fuels as we have so far, also now that China and India wants to join the consumer party, we'd reach a number of 900ppm CO2.

    So my question is... Are we gonna be a planet of zombies when we reach the year 2100?
