  1. Concerning the CO2 graphic labeled “Past 500,000 Years”:

    The time span in the insert is essentially a vertical line in the scale of the main graph and appears to begin near the top of the latest natural warming cycle. The result is a CO2 level that now exceeds the historic high point by an amount that is approximately equal to the entire CO2 deviations noted in the past 400,000 years.

    A couple of questions come to mind:
    Since the temperature hasn’t risen nearly as dramatically as the CO2 rise, does that not give credence to the concept the CO2 warming effect has approached saturation with diminishing temperature sensitivity to additional CO2?

    The high level of CO2 is going to stick around for a while. If the human race immediately died out, would that significantly change the temperature trend that has already been attributed to the current CO2 level?

  2. The increase in co2 over the last 100 years is only 1/100 to 2/100 of a percent. Really not enough mass to create a greenhouse effect. Methane is even much lower. Also, there are 36 volcanos erupting currently. The average for the previous century was only 36 per year. Sulfate aerosols cool the earth. Shown by previous VEI 6 eruptions. Plants and some animals thrive on co2. Plankton blooms will increase as the sink rate of co2 increases in the oceans. Trees and especially pine trees are great absorbers of co2. There have been increases in reforestation in some areas despite the ongoing deforestation. People need to understand how Gaia works to keep the planet optimal for life to thrive.
    There is also a noticed increase in solar energy output. And the albedo of the earth has also changed.

    1. Over the last hundred years atmospheric CO2 has risen from approx 295ppm to 407 ppm…almost a 39% increase. How did you arrive at .01% ??
