More dust less trees?!

If there is a naturally dusty area, especially around the ocean, planting trees to keep the soil on the ground rather than in the air may actually contribute to global warming. Plankton in the sea feed off the dust and absorb more carbon dioxide than a stand of trees do. However, it is very hard to tell which areas are naturally dusty and treeless, and which have been made that way by humans.
