even if an experiment was devised with enough precision and accuracy to produce some portion of the 1-1.2C warming per doubling of CO2, would that be a 'victory' for the skeptics or the warmers?
the skeptical position is not that there is no change from increased CO2, only that the exaggerated claims of 2-6C warming this century are ridiculously improbable. this millenium has crushed all of the warmers wild predictions.
it is time to go back to the drawing board and redesign models with more realistic assumptions rather than continue to hope and pray that some gigantic resurgence of warming will reverse the fortunes of the doomsayers.
IMO, both win. We get our evidence we've been arguing for and the warmers get satisfaction they were right if the results back their claim.
However, since none have been provided, I can only conclude the tests performed did not back the claims in those labatory set ups. I personally believe there is no evidence to support the claim.
