Best plan is to chip off the ice and package it as ice cubes and also use the meltwater to make “Greenland Ice Water”.
All the water will end up on land and get ‘recycled’ into groundwater.
You can use it to fill up suburban swimming pools. All winter long, it’ll stay more or less frozen, then comes summer, you add some chlorine, turn on the filter, and it’s fun for all the family! Capitalism. Exploitation. It’s great!
