if the emails that were leaked were fabrications, then one might reasonably conclude that climate-change skeptics (no doubt funded by exxon-mobil etc) were engaged in a smear campaign. but since no one appears to be asserting that the emails aren't authentic, i'd say y'all smeared yourselves.
i don't doubt that the climate-emergency lobby is sincere. it's interesting how one discredits oneself in one's urgency; i think as disturbing as anything in the emails are the indications of active suppression of results in tension with the declaration of impending apocalypse, the assertion of control over peer-reviewed journals, etc. then of course the fact that there's no criticism in the journals is used to show that there is a consensus. the whole idea is to discredit your opponents,thus helping to save the world, but the effect is to discredit yourself. it might appear obvious that if you have the truth, you should impose it by totalitarian means: you have to enforce the truth, amply justified because it is the truth. what you create is a situation in which you are impossible to believe, even if you are in fact right.
john dewey and karl popper, among many others, connect science to democracy and freedom: only an hypothesis that is completely open to criticism can be taken as having been rationally supported. here we see one aspect of this: when you learn that disagreements were suppressed, you realize that you have no reason to suppose that the claims are true. in manufacturing unanimity to mobilize us into action, they leave behind anything that had anything to do actually with establishing the truth of their claims: they exempt them from testing of the sort that would show them to be plausible. and they undermine their credibility entirely: show themselves to be people for whom finding and saying the truth are not the primary motivations.
that doesn't show that what they're saying is false; it shows that they are false. and it certainly undermines the claim that what they are saying is supported by the evidence. we don't know whether it is, and essentially they no longer care whether it is, even as they chant it continually like a mantra. that's why al gore and tom friedman aren't scientists and that's why the scientists whose results they deploy are not scientists either.
