New satellite images suggest that the Earth is getting dustier. Well, not necessarily, chimed in Dan Muhs of the U.S. Geological Survey. Scientists increasingly turn to satellite images to track dust plumes in the atmosphere.
“The ability to monitor dust plumes is better now than in the past. This new information gives us a better appreciation of atmospheric dust,” said Muhs.
And it is important to study dust, because it is, in the words of Karen Kohfeld of Simon Fraser University, Burnaby Canada, the great communicator of the Earth System. “Dust links the land, air and sea system,” said Kohfeld.
