We are discussing climate science. If the person I was trying to convince was so ignorant of the subject to not even know what IPCC was, I would point them to the body, its website, and NASA for summarized data.
If someone who wants to drag out useless arguments online without addressing real datapoints wants to pretend like "IPCC Is so foreign", then you are just wasting time.
You know what the IPCC is. You can find reports from NASA. You know the body of research out there. Why aren't you engaging with it? You decry the lack of discussion, but you won't even engage with the highest quality of research available on the topic.
Calling out a fallacy without substantiating further is just arguing for the sake of arguing. Either engage usefully or stop question begging.
