People that argue consensus are missing that the bandwagon fallacy or appeal to authority fallacy are not persuasive to the rational/informed. Consensus/popularity is politics. Science IS skepticism. If they have no pedigree, accomplishments or evidence, then they're just cherry picking their data (another logical fallacy).

Here's studies or groups that oppose claims of AGW, or admit that there's been extremist claims:
- PetitionProject: 31,487 American Scientists (9,029 Ph.D's), signed up as skeptics
- A hit list of the enemies of the Church of Climatology is being tracked to pressure Scientists from exposing the truth. That's not Science, that's politics of hate and intolerance. 
- NASA has some leaders that promote Climate Change Hype for government money... but their Scientists usually disagree with their management. 
The left is a crusader for free speech. Wait, you understand that man-made global warming is an exaggerated crisis? Burn the witch! The Obama Administration and many state's Attorney's General banded together to bring lawsuits against corporations who disagreed with the mythical climate consensus, and was threatening to do the same to individuals. Multiple others on the left were floating trial balloons on laws to oppress or persecute Climate Skeptics. While far left tech places (Facebook, Google, Wikipedia) were falsely de-ranking or shadow banning climate skeptics stories, no matter how accurate.
If you think you know more than these folks, or they're all sell-outs to the oil companies, I want your evidence. That's incredibly bold and ignorant statement, that nobody on the other side is informed or has integrity -- those kind of assumptions scream ignorant fanaticism. So when someone claims the skeptics are all malinformed or lack professional integrity, they need to be challenged to make society a better place.
