Ah, it is all Mercator's fault
Feels like the exception to the rule that Mercator has no impact. Probably not coincidence it involves the head of state whose arguments that Northern California could water Southern California appears to stem from belief that water flowing from north to south is going downhill all the way :)
Mercator projection aside, Greenland is not tiny. The ice-free area is about as big as California. If you include the icy areas, it's bigger than any U.S. state.
