Re: "this comparatively reassuring picture"

"We base our computer models on what we think is representative, then derive conclusions from those models without double-checking the source data."

That's unlike any computer modelling i've heard of, or implemented. Can you explain why you think this is true, or is it just a feeling of yours ?

"Let's keep on measuring, evaluating and improving our understanding, hmm ? It's the only way to learn, and zealots be damned."

That's a very good idea - it's called science.
