Look at the DATA on the next chart! This CO2 data was sent to me in December of 2009 by:
Thomas C. Peterson, Ph.D.
Chief Scientist
NOAA's National Climatic Data Center
NOAA stands for the National Oceanic and
Atmospheric Administration.
NOAA scientists study the skies and the oceans. (their words)
CO2 did follow temperature when it could. About Seven Thousand Years Ago it stopped following Temperature and it has been rising with no connection to Temperature. Temperature does not care what CO2 does. The Thermostat of Earth, Polar Sea Ice and Water, does not care how much heat CO2 can trap, the thermostat turns cooling on that can handle all of it easily. When the Polar Sea Ice Thaws, it snows as much as necessary to stop the warming and start the cooling and continues until the oceans are cool enough to allow the Polar Oceans to freeze again.
If you include modern recorded temperature and modern recorded CO2, you will get even more disconnect between Temperature and CO2 than is shown on this chart. Recent CO2 Parts per Million did reach 400, well above the scale on this chart.
Temperature is well bounded and not following CO2.
CO2 has gone up more than one hundred parts per Million since this data was published and temperature has stayed in the same, stable, well bounded cycle that it has been in for ten thousand years.
