What kinds of feedback loops is the IPCC known to exclude, and is there any serious study into what the potential consequences are? Like, how possible is it that there is a feedback loop that will push us well beyond the RCP8.5 scenario?

Two examples I recall are the albedo changes from melting of on-land glaciers and ice-sheets, the IPCC thinks think will take hundreds of years. And then the Methane Clathrate idea, which is very controversial but could contribute to some degree.

I don’t think anyone in the world can answer the question about how likely these feedback effects are, unfortunately!
