Atmospheric Dust
It鈥檚 estimated that at any one time, there are millions of tons of dust suspended in the atmosphere, but scientists are a long way from understanding its impact on the Earth鈥檚 climate and weather systems.
Last year, scientists at Columbia University鈥檚 Earth Institute showed for the first time that dust from the Taklamakan Desert in China had been deposited in the French Alps, more than 20,000 kilometres away.
Environmental Impact
Better monitoring and more sophisticated sensors are giving us a more accurate picture of the dust in the atmosphere.
But the unpredictable nature of dust events makes it extremely difficult to determine their impact on the Earth鈥檚 natural systems.
Peter Evans talks to geographers, oceanographers, environmentalists and climate modellers about atmospheric dust, one of the least understood, and most contradictory, components of the Earth鈥檚 atmosphere.听
