"Science fallacy": Anything coming from a scientist or a science/research group/organization becomes "scientifically proven" and therefore "the truth".
Sounds like "appeal to authority" to me, but the way you stated it, it looks more like a straw man.
The reason to trust scientists is their method, which gives a good approximation to truth. If you are capable of evaluating their results yourself, then you don't need to trust them, but if you aren't, you have a good reason to trust them, even if technically committing the fallacy, because what else are you gonna do?
