Correlation (especially when the CO2 is lagging) is not causation.
And can you point to one peer-reviewed scientific paper that conclusively states that any global temperature is caused by man-made CO2? Just one paper, eh?
AGW is just an unproven theory. Every year more data comes out which disproves it.
Look! I'm agreeing with you!! This sudden rise in temps which is melting all the ice is just natural variation from cosmic rays or something and not from the 42% rise in the earth's most important greenhouse gas. Tyndall, back in 1860, was wrong about his lab measurements of greenhouse gasses and no-one has corrected him since.
