Have the Antarctic Ice Sheets reached the Point of No Return? My last entry was an excerpt from my memoir about flying past the Point of No Return (AKA Point of Safe Return) in route from Christchurch to McMurdo Station, Antarctica. This entry is about an entirely different PNR, that where the stability of the West Antarctic Ice Sheet (WAIS) is lost.
About the area of Mexico, if the WAIS melted entirely sea level would rise an average three meters around the world (ten feet).
