Fred Moolten: MattStat – the net imbalance over the past decade might have been zero or close to it – that was one of my points about short term data.
I hope, though, you’re not suggesting that the rising CO2 over the past century didn’t contribute to the net positive imbalance during that time. That would put you in the SkyDragon category.
If the net imbalance over the last 10 years was 0, the decade with the highest atmospheric concentration of CO2 in centuries, then it is indeed possible that the net imbalance is unrelated to CO2. And if net imbalance was unrelated to the maximum concentration of CO2 over a decade, then it might have been unrelated to lower concentrations of CO2 over a century.
The problem with the Skydragons is that they tried a proof that CO2 change was necessarily unrelated to heat flux change. My claim is that extant knowledge, data and reliable applied math (what some call [pure] physics), is unsufficient to establish a reliable claim one way or the other.
