Since part of the OP addresses scientific concensus and by implication peer review I would just like to comment specifically on that.
The peer review system has come up for heavy criticism in the past on other contentious issues. I find it odd that we have to rely on the words of a few reviewers on any topic covered by science.
The most important peer-review is post-publication.
In the past, information was much harder to get at and review, but now we have computers that can send information across the entire planet in the blink of an eye. Why not make all submissions to scientific journals be posted openly to the public?
Because they might be submitted to other scientific journals if one doesn't accept it for publication. That might not be because it's bad science but because there are limitations on space, or because it needs some more work. Scientists are often grateful for peer review because it prevents them from making mistakes, and improves their final product.
If worst comes to almost worst there's Energy and Enviroment if it has the right message, and at the really worst Anthony Watts will feature it. Again, assuming it has the right message. It won't carry the imprimatur of a respected journal with standards to maintain, but not everybody cares about that.
The technology is there. You can even use technology to "drown out the noise" by using various settings.
Peer-review serves the same purpose rather more intelligently.
From what I understand most scientists now do not read journals in physical form anymore anyways, and yet Universities and other major scientific players still pay incredible sums of money on journal subscriptions.
The sums are perfectly credible, despite postage, and what they get is a serious reduction in "noise". Also no paywalls on the internet for students and faculty.
As for concensus, that should never be a goal of science. At best, concensus should be something that happens organically over time.
Indeed. The goal of science is to get to the truth of the matter, and the consensus (when there is one) is where you start from in the morning. When the consensus proves to have gone up a blind alley that becomes clear and scientists back-track to where things aren't clearly wrong. Some will go even further, but seldom to absolute first-principles.
A good example of this can be found in the accelerating expansion of the Universe. The concensus was that it was decelerating due to gravity, and when results were published (after peer-review) suggesting otherwise considerable doubt was expressed by all concerned. When supporting evidence emerged from different lines of investigation the consenus was abandoned, in very short order. Now there's a consensus on accelerating expansion, but no concensus on what's causing it. Exciting stuff. Like string theory used to be
