Your examples are too broad and/or poorly defined. An appeal to authority fallacy has to be without reason backing up the appeal other than the fact that they are an authority. You can suggest that a source of information might be unreliable because of a poor track record in the the domain, or a conflict of interest - that's not ad hominem. One can speak against the direction of a policy without committing a slippery slope fallacy by not making unsubstantiated claims about what will happen. If you can cite examples of similar policies that have led to effect Y happening with rational explanations for the causes along the way, then that would avoid the fallacy.

Well, for example if somebody asked me the circumference of the earth and I replied with "40,075 km" how do I actually know that? I certainly have never measured it, so all I can do is cite sources of information which are assumed to be authorities. I can be relatively confident in my reply by citing multiple sources of information but I'm still ultimately relying on something I can't realistically provide other evidence for. According to wikipedia the second could possibly fall under "Circumstantial Ad hominem" in that suggesting a source has bias does not necessarily make them incorrect. Though this depends on the nature of the argument. I think the third is more tricky to pin down because it is going to depend again on the nature of the argument. You may suggest concern about some policy without a concrete example of X leading to Y because it may not have happened before. But again this depends on the nature of the argument. I think my problem is more with the way in which logical fallacies are abused in internet arguments rather than the fallacies themselves. For example somebody saying "You are wrong to be concerned about policy X because slippery slope fallacy".

  1. Yeah, this will probably be an accepted fallacy for day to day usage. You could quote leading geologists/physicists and the implication is that they have a vested interest in being correct. But the reasoning there isn't just "Because they're experts, so trust them!", it's "They purport to have measured it and I trust that they did so accurately because of their position as leaders of their field and their desire to remain as such.". Still technically might be a fallacy, but I would accept it in the case of a casual conversation about the Earth's circumference. 2. Agreed that it's contextual. I merely wanted to point out that not all discrediting is ad hominem as you seemed to imply. 3. Also agreed that it's highly dependent on context. Again, just pointing out that one can speak out about policy direction without committing a fallacy. And yes, I dislike that as well!

  Simple way to verify rough correctness of 24k mile circumference of earth: Most people know ca is ~3000 miles from ny. Most also know that the time difference is 3 hours. So 1 time zone is approx 1000 miles. Circumference = 1000 mi x number of time zones.

  If you've got nothing to go on but second-hand information that you can't validate yourself, then it's perfectly reasonable to use qualities like "credibility" and "authority" as a sort of Bayesian indicator of the likelihood that the statement is a valid one. The "appeal to authority" is only a practical fallacy in a situation where it is feasible to directly evaluate the claim against reality itself.
