Temperature Change and Carbon Dioxide Change
One of the most remarkable aspects of the paleoclimate record is the strong correspondence between temperature and the concentration of carbon dioxide in the atmosphere observed during the glacial cycles of the past several hundred thousand years.
That chart's a few years old. In the meantime, CO2 is over 400 ppm. If the relationship had held as the warmenists predicted, then it would be about 10C warmer than it is, which it clearly isn't.
Their 'climate models' need a few more tweaks to explain that one away, don't they?
