oliver, i'm not sure what you "don't get about the whole last thread". the discussion seemed pretty straightforward, whichever point of view you're coming from. i did ask for the specific reference on cooling from your published papers. you've pointed me at your entire publication list--quite lengthy. would you mind just sending a pdf of the specific paper?
i'm quite surprised at the < 1% number above. is this what has been simulated in your model results? so you're saying that the natural rate of productivity in the southern ocean can only be increased by < 1% without disastrous consequences? one would assume that is less than the likely margin of error in the model itself, no? what happened during the last glacial/interglacial? would the effect have been the same? what should victor be looking for during the lohafex experiment this february to corroborate this prediction? SST? d On Dec 16, 8:34 pm, Oliver Wingenter <[email protected]> wrote: > Dear Dan, > > I don't get the whole last thread.
