> Worst case if Greenland's ice sheet melts, that adds 7 meters to sea level, and Antarctica's another 60 meters. I won't see that in my lifetime but my children might. How likely is this worst case? IPCC in 2021 [1] projected a 0.5 m to 2.0 m sea level rise by 2100 (see Figure SPM.8) and NOAA in 2020 [2] suggested a worst case of 2.5 m sea level rise by 2100. It appears that neither are considering the possibility of an entire ice sheet melting?
