    Seth says, “Mann’s hockey-stick result (a sharp increase in global temperature to unprecedented levels during the 20th century)”

    That’s strange. I always thought the hockey stick was a plot of historic CO2 levels. All this fuss has been about a predictive temperature plot?

    Yep. Mann’s hockey stick plots time on the x-axis and temperature on the y-axis.

    1,000 years on the x-axis and +/- 0.5degC on the y-axis. That’s not a hockey stick, it’s a candle with a bent wick.
