They store most of the land ice (~99.5%) and have a sea-level equivalent (SLE) of 7.4 m (24 ft 3 in) for Greenland and 58.3 m (191 ft 3 in) for Antarctica. [6] Thus, melting of all the ice on Earth would result in about 70 m (229 ft 8 in) of sea level rise, [ 83 ] although this would require at least 10,000 years and up to 10 °C (18 °F) of ...
