The potential urgency of devising responses to tipping elements is illustrated in Table 1, which is derived from Armstrong McKay et al. (2022). The minimum estimates of the global mean surface temperatures that would trigger many of these tipping elements are in many cases well below 2ºC, and expected tipping temperature values for key tipping elements such as abrupt permafrost thaw and subpolar gyre (SPG) collapse are also below 2ºC5. These tipping temperature thresholds will be surpassed irrespective of which Representative Concentration Pathway (RCP) the world ultimately selects. Even diverting to a radical emissions reduction scenario such as RCP2.6 would not prevent us from crossing before 2050 the minimum temperature threshold that might trigger a tip of the Atlantic Meridional Overturning Circulation (AMOC)5. It is possible that we have already crossed the thresholds that might lead to an irrecoverable loss of the West Antarctic or Greenland ice sheets5. Or, those thresholds may lie just ahead.
