No, the evidence for the anthropogenic nature of climate change does not come from climate models about temperature increase. It comes from the empirical evidence we have for current warming, an understanding of physics and looking at observed temperature. The models are used for an estimation of climate change, but we have the evidence of the anthropogenic nature without them and no other explanation can match.
I don’t care about credentials, I care about the argument. The fact is Christy is outnumbered by so many climate scientists, so if climate scientists is of any importance, these others would matter more. Oh, right, everyone who disagrees has to be a shill for a supercomputer. Yawn.
Anyone familiar with Christy knows his arguments are bunkum. Another typical ‘sceptic’ who uses misleading graphs to cherry pick data which agrees with him. For example, he commonly uses inappropriately small baselines for satellite data and measurements of atmospheric temperatures. Other climatologists have argued how this skews the output. This is why, I suspect, Christy shows inappropriate baselines. The model errors are much larger, so it suits his narrative. Look at more appropriate baselines than 20-30 years in the atmosphere and the errors decline, and the evidence shows that the errors decrease. Going beyond that, there are complaints about inconsistent smoothing of data, which sets alarm bells of manipulation to suit his own interpretation and he doesn’t publish uncertainties in his data. He is guilty of the very thing you accuse others of. He is free to spout what he wants, but it’s important to acknowledge the very real questions in what he is saying. That’s all I will say, as I am not getting sucked into this. It’s been done to death and previous arguments have failed to convince me.
Of course, none of this can be in good faith, because anyone who dares to disagree with the ‘sceptics’ have to be in on some conspiracy for a supercomputer (I wish I’d get more money, if so), and it cannot be there are flaws in their work. That’s too much for their ego.
