#2911: Greenland Size

XKCD comic, described below.
Transcript

[Cueball and White Hat are looking at a world map on the wall showing a Mercator projection, with Cueball gesturing with his hand towards the map.]

Cueball: This map is really misleading about the size of Greenland.

Cueball: It's actually much bigger than that - it's hundreds of miles across.

(Sourced from explainxkcd.com)

The Mercator projection drastically distorts the size of almost every area of land except a small ring around the North and South Poles.
