We all have seem how this "consensus" is being build. See above
I've noticed a jerry-built edifice dependent on sky-hooks constructed to house an incredible description of the scientific consensus. Many of us have seen how the scientific consensus has
really been created over the last couple of centuries.
The scientific basis of AGW are based in computer models with no predictive value, full of erroneous data and already invalidated (as Lockwood study says in essence). Also, see above.
The scientific foundations of AGW include thermodynamics, quantum physics, and fluid dynamics. That's the sort of theory that is built into physical models, such as the climate models that have performed so well. (Ice-dynamics models have far more to contend with, and have not preformed so well, but there's no shame in that.)
Politics and partisan groups have enormous sums of money dedicated to studies who can confirm AGW. What is interesting is that there are no similar amount of money dedicated to research of methods to control GW or find alternate sources of energy.........there are almost invisible. The majority of the money goes to studies who confirm AGW. This should trigger alert signs, because that's supposed to be proved.
Why hasn't Exxon funded research into AGW? The results could hardly be regarded as tainted since it would have to be rigourously transparent on the "only Nixon could go to China" principle. They're not short of a buck, after all, these "enormous sums of money" you mention are small change to them. (Ten billion operating profit last quarter. Tasty money by any standards, even in dollars.) They're socially concerned enough about truth in science to fund groups that purport to be about just that, so why not a few million for a modelling project? All code and data publicly available, all procedures transparent, a completely hands-off approach. It would put your mind at rest, wouldn't it?
So why not? The cynic in me says that Exxon knows perfectly well what the outcome would be, so instead they leave the science to others and snipe at it by proxy. My other side says ... actually, I don't have another side. It's cynic all the way down.
The sun is other credible candidate.
Directly observed by dedicated satellites for decades and didn't do it. Not credible, unless it has a double that was on the other side of town at the time.
Natural forces are other credible candidates.
No supernatural force would be a credible candidate. CO2 is a natural forcing, solar variation is a natural forcing (been there, watched that, nothing happened), orbital variation is a natural forcing, continental drift is a sloooooooooow natural forcing. "Natural forces" smells of the woo a bit.
Now take the massively dominat CO2 force and higlight the human produced CO2. That way you can have a clearer picture.
The burning of fossil fuel puts more CO2 out there anually than is accumulated in the atmosphere and oceans, so there's not much (if any) room for any other significant contribution.
And so is CO2, at least in recorded history.
What's going on now is not represented in recorded history. It's not represented in history at all, unless a technological civilisation such as ours sprange up way back, did what we've done, and vanished without leaving a trace. Which isn't credible. Even if they were a lot tidier than us they'd have mined out the easy-access minerals and fossil fuels that we found waiting for us.
