@Brad_Rosenheim Yes! Monitoring of tipping points and earth system feedbacks would be good to do. I looked through the 374 page tipping points report (https://global-tipping-points.org/) that came out before COP last year and saw one example of something actually being measured. Most of the tipping points remained somewhat nebulous, modelled risks, schematics etc. Occasionally, a paper will come out with a suggestion, but I don't know of anyone doing routine monitoring of tipping points, at least not the way we monitor global temperature, say. Probably ignorance on my part. However, it seems difficult too. Part of the difficulty is the availability of obs. Part of the difficulty is communication. Part of the difficulty is time scales which can be long with important changes stretched out over decades. Part of the difficulty is that, in many cases, we won't know when we've passed a tipping point even if we're watching it very closely.
