Therefore, to argue that "most scientists agree" in context of "this matters for science" is anti-scientific. You can argue that most studies etc support this conclusion
You might have a point if there was a disagreement between "most scientists" and "most studies", but there isn't.
Nobody claims that science should follow consensus, or even that consensus is important for science. Consensus is only relevant when you want to take a body of scientific knowledge and turn it into something that laypeople can use it to inform themselves and make policy decisions.
Yes, people get it wrong all the time, but we still have to make decisions every day, and consensus is the best tool we have. Scientists with a different viewpoint are welcome to continue their research and try to convince everybody else.
If the models are improved, that does not "move the goalposts" in any way. Why should anyone want to run a less accurate model if they have access to a better one ?
If your argument is that the models have been manipulated to fit the narrative, then you need to present the evidence for that.
You can look this up yourself. It is in every version of the UN Climate report ever published.
The UN climate report represents the consensus view of climate scientists. It sounds like you're just complaining about popular press/politicians not being entirely accurate in representing it in the media.
So... how does that compare to our (newly reentered) Paris Climate Agreement goals? We done or just 40% there?
Since most of this is from COVID-19, we should wait and see what happens after the epidemic is gone. Most likely CO2 emissions will bounce back up, but we don't know to what degree. It is possible that we'll keep working from home more than before, for instance.
as if the truth is decided by popular vote or consensus instead of evidence...
The problem with that view is that you need an expert to understand the evidence. Somebody may collect some piece of evidence, for example about the Arctic & Antarctic ice, and then come up with a hypothesis to explain the observations in a scientific paper. But you can't expect laymen (including politicians) to go read that paper, and all other papers, and form a good opinion.
So the obvious solution is that the politician asks a team of scientists to read the paper and translate it into something they can understand. If the scientists don't all agree, then you have to form some kind of consensus view with the most likely explanation.
Even if life is forming easily, intelligent life capable of making technology is another matter.
It took only a few hundred million years to form life on Earth, but it took another 4 billion before that life had invented a radio.
If it had taken another billion more, the Sun would already be killing it.
As long as we're going to reinvent the wheel again, we might as well try making it round this time. - Mike Dennison
