    janti, you say
    "... in the early 1800s - as you say, two hundred years ago. The only problem with the AGW crowd's hypothesis is that CO2 levels then were in the 420 - 480 range; above what they are now..."

    do you have a reference for that?

    everything i've seen has shown co2 levels below 300ppm at that time.
