What's that figure eight thing that you see on some globes?

Question

Apparently it is a scale of some sort, but I'm not sure how to use it. Why wouldn’t a scale be linear anyway?

Answer 1

He spelled it wrong, but its an analemma. To be lazy, here's a copy and paste from Wikipedia.

In astronomy, an analemma, Latin for the pedestal of a sundial) is a curve representing the angular offset of a celestial body (usually the Sun) from its mean position on the celestial sphere as viewed from another celestial body (usually the Earth). For instance, knowing that Earth's average solar day is almost exactly 24 hours, an analemma can be traced by plotting the position of the Sun as viewed from a fixed position on Earth at the same time every day for an entire year. The resulting curve resembles a figure of eight.

Answer 2

It's called an Annalemma.
