As @Ruth_Mottram points out, the answer to your question depends heavily on the used definition of the ‘tipping point’ term.

See this table from the report: https://global-tipping-points.org/section1/1-earth-system-tipping-points/1-2-tipping-points-in-the-cryosphere/1-2-2-current-state-of-knowledge-on-cryosphere-tipping-points/
