Trump wants to buy Greenland, because of course he does. Reading the coverage, it struck me that media generally prefer to use the Mercator projection when showing the island. This is because we think it's funny to depict Greenland as a vast place as large as North America itself.
Though all 2D projections of our very 3D planet are distorted, this particular projection was designed for navigating equatorial seas and is ludicrously obsolete and inappropriate for depicting arctic regions. Instead, here's a general perspective projection–the globe as if viewed from space–that shows Greenland's true size, relatively undistorted compared to neighboring regions.
Still a big place—just not as big as the BBC's misleading map would have it. (Which is crudely inaccurate, too, with that distance marker)
