Cheers, yes had noticed vapour looked remarkably similar to temp.
Data format , many yrs experience modelling, dif field though, but know enough such that wouldn't be surprised if any one of a number assumptions/approximations when adjusted could swing the outcome of their models to a completely different direction.
Can't quite recollect what sort of magnitude the AGW'rs were looking for with OLR change over this century, is it something like 1 W/m^2? Been many months away from this field.
