If I remember from the last time I was reading about it, the IPCC wasn’t using models that include feedback loops because they tend to be fairly conservative and there’s a number of different ways assumptions can be made.
I’m a biologist and not a climate scientist, but my understanding is that while feedback loops are widely accepted as being part of the dynamic, there’s a number of different approaches and those are available in individual modeling projects but not in the consensus models. I’m not sure if that’s changed, though.
The IPCC report must be agreed upon by representatives from every country. Including Saudi Arabia, and USA. So you can imagine how “conservative” it is compared to reality. Anything slightly uncomfortable gets negotiated down to the point where the oil-producing countries are fine with it.

If people find the IPCC reports alarming as they are, imagine how alarming the draft from the scientists is before the Saudis, Russians and Americans get out the black markers.
This is largely because we simply don’t have the capabilities to model these systems with the accuracy needed to make useful predictions. Individuals, however, should absolutely be aware that things can go bad far quicker than we’re able to deal with.
