Thoughts from Zorita

Eduardo has quite a nice post at KZ. I say “quite nice” because it is definitely one for those deeply emeshed in the debate and familiar with it, yet not wanting to be part of the rancour.

Point 1 should be required reading for all the septic folk out there:

The main question here that any scientist would like to answer is what are the factors or combination of factors that have caused this warming. Note that even if temperatures had been much higher in , say 1800, even much higher than today -which I doubt – this question would remain. We see a change and we have to find an explanation for that change… By this I mean among other things that, for instance, ‘recovery from the Little ice ‘ is not a known physical process that is described by any known equation. Also, natural oscillations are not a known physical phenomenon per se. If there is a ‘natural oscillation’ there is something that oscillates and for some reason. What is that and what makes it (quasi) oscillate ? Neither is an answer of the type ‘it was warmer in the Medieval Warm period, so I dont care’ permissible. I think t we all should require physically consistent explanation from any theory of climate change, and not only from the anthropogenic greenhouse effect.

Quibbling, it would have been nice if he had added that AGW does provide an explanation, and nothing else (so far) does; but as I said, this is for those emeshed in the issue and that can be justified as implied background.

His point 2, though, isn’t so good. Its more of a speculative by-eye assessment of the graph and doesn’t help anything much. Point 3 is interesting speculation.
