Isn't it funny - ironic, really - that these "it's different than we thought!" only go one way?
Just to clarify, you're claiming that when scientists attempt to correct themselves based on observable evidence, that the observable evidence seems to always be above the predictions, implying that scientists chronically under-predict. Correct?
If they were chronically over-predicting, would you not be exclaiming: "Wow, these guys are always predicting the sky falling!?". Tell me I'm wrong here. I don't think I am.
So I'm guessing that no matter which way they end up predicting (under or over), you would have a problem with it. Am I right? Have a serious think about whether that exposes your bias or not.
And they assert it with such absolute certainty - no "yeah, this is a climate model, #405599 that we've run, and all of the previous ones were off the mark. But this one we got right."
Can you point out where the article expresses absolute certainty? Here's a small snippet from the article to help you: "It’s important to emphasise that both of these issues – [pollution cuts] and climate sensitivity – are areas of deep scientific uncertainty,” he said."
It would help your case if you learned to read before expressing an opinion. It might help avoid other people dismissing you as "full of shit". Not me, of course. I think you're completely onto something here...
