Climate Change

Direct Effect in Action
• Dust Storms – dust storms obscure the surface
of the Earth as seen from space. They are
brighter than the land and ocean around them
(slightly increasing the albedo of the Earth).
– Dust storms can extend over far distances. There
have been instances in which dust from China has
reached the western coast of North America (and in
some extreme cases reached Colorado). An example
of one of these big storms reaching the California,
Oregon and Washington coats occurred on April 25,
1998.
