Its just that periods of cooling have also occurred with increasing c02 levels. Thats all. It doesn't always correlate.

True, CO2 levels and temperature don't always move in lockstep. Short-term cooling can happen due to natural variability like volcanic activity or ocean currents, even as CO2 rises. But over longer periods, the warming trend dominates. Look at the data: decades show the link, even with blips. Thoughts?
I think there are other explanations that might be overlooked. On the surface, the data looks biased toward a political agenda.
