Only about 20% of the world's deserts are sandy.

A glass of milk left in the Lut Desert in Iran will not go off: the heat is so intense it kills all the bacteria.

Deserts represent about one-fifth of the Earth's total surface.

In six hours, the world's deserts receive more energy from the Sun than humans consume in one year.

The only desert in Britain is Dungeness Nature Reserve in Kent.

Around 46,000 square miles of arable land turn to desert every year due to climate change and practices such as forest clear-cutting.

The Sahara desert stretches for more than three-million square miles.  It is three times bigger than the Arabian desert, which itself is twice as big as the Gobi in Mongolia, which in  turn is twice as big as the Great Basin desert of Utah and Nevada.
