DESERTS AND GLOBAL CLIMATE

DESERTS AND DUST

CROSS-DESERT RIVERS OF NON-DESERT SOURCES

Deserts are not only highly constrained by water, but their water supply greatly depends on climatic processes operating away from them, either those involved in the generation of desert rainfall, or in generating flows of rivers that enter deserts. Deserts also have effects on climate beyond their boundaries, either directly or through the dust they generate.
