Plays. The lead dust storms are scourge of modern life in much of the world in order to produce a dull story you need to win and we need soil particles tom murray in this film we look at malta dust storm moves the storm is actually when the visibility is less than a kilometer. And how human activity is making them was plain we focus on the middle east such a being called one of the walls was to his aries plate during the dust storm season and patients get severe attacks of us and thats required hospital admission and intensive care. Well see how nasa satellites can track dust storms as they sweep across the globe the dust to lift it up to three or four miles in altitude before its. Really kind of scary the way by the dozens. Every year the current estimate is anywhere from two to five billion metric tons of news around some just as a nurse atmosphere every year so thats quite a bit of dust. Just isnt always passed scientists are researching the impact of dust crossing the ocean from af
