  2. BBB (@1): Interesting information. Could you reply w/ the list of 13 tipping points, and the 5 that will be tipped at 1.5-2.0C. I would like to see/know that list. Thanks!

  4. Sauerj, the 13 climate tipping points are listed in this article on a useful map.

  5. nigelj @4,

    The article you link-to is based on Steffen et al (2018) 'Trajectories of the Earth System in the Anthropocene' which, even with Schellnhuber as a co-author, doesn't provide a list of tipping points projected for +1.5-2.0ºC. The source of the Fyson & Rahmstorf quotes @1 appears to be this web page which does lists five tipping points, referencing a graphic presented within a YouTube video which is Fig 1 from Schellnhuber et al (2016) 'Why the right climate target was agreed in Paris'. This Fig 1 does show thirteen 'tipping points' (if you can call them that), of which five begin to 'tip' below 2.0ºC with one of them entirely 'tipping' below 2.0ºC.
