In that case if the ice cores vary so much it invalidates your statement:

"then they totally ignore the fact that the co2 increase came about as much as 150 years after the temperature increases they supposedly caused"

You can't have it both ways. How do you come by the statement, if not by the data from ice cores? And if they are as unreliable as you say then...


...we rely upon what we do know:

1. Greenhouse gases in the atmosphere trap longer-wavelength solar radiation from the sun, thereby raising the temperature.

2. We are putting more greenhouse gases into the atmosphere than would occur naturally.

Now join the dots.
