Are all deserts hot?

The definition of a desert is a place where the lack of moisture makes it impossible for anything but a few special life forms to grow. This applies not only to hot places, like the Sahara and the Gobi deserts, but also to very cold places too. Because all or most of the moisture there is turned to ice, almost nothing can grow there, which makes it a desert. So, you see, a great deal of the Artic is desert as well as the hot places people think of as being deserts.
