So you think the scientists who form your 'scientific consensus' have a thorough understanding of how Terra's climate operates and are all qualified planetologists.
Being that planetology is a field in astronomy, I think that very few climate scientists will be qualified planetologists.
Now, I do see that the methods of climate scientists are sound, and that they display honesty and integrity. And that unlike the deniers, they have no political axe to grind. And that they're taking a pay cut by not shilling for deniers. Follow the money. It's flowing _away_ from the reputable scientists, which gives them more credibility.
I can also see that the whole planet shares that judgement. Being that I'm not insanely narcissistic, I don't think I'm a special snowflake who is more brilliant than the rest of the planet. If the whole world agrees on something, it's probably for a good reason. If I was going to declare the whole world to be wrong, I'd make sure I had rock solid evidence first. I certainly wouldn't just say "The world has to be wrong, because my fringe political cult believes it.", as deniers do.
While other scientists who've reviewed the data and disagree are to be discounted because they aren't working in the AGW field...
They're discounted because their methods are bad. Most of them don't actually do any science, and instead just shake their tiny fists at the sky. The ones who try science make obvious basic errors, or they fudge things. Hence, they have little credibility.
Isn't it funny how the only scientists polled for your 'scientific consensus' work in the field of AGW I'm sure there's no bias there.
Bias towards the truth, yes. Why would you poll people with no knowledge in the field?
