Huge dust clouds swirling across the Atlantic from northern Africa to South America are pictured in stunning new images released by the US space agency Nasa that illustrate how Earth’s largest tropical rainforest relies on its biggest, hottest desert to flourish.
Scientists have now for the first time calculated how much dust makes this transatlantic journey from the Sahara to the Amazon basin where it fertilises depleted soils with life-sustaining nutrients.
Some 27.7 million tons of Saharan dust reaches the Amazon basin each year, according to analysis of three-dimensional imagery supplied by a Nasa satellite of the massive tan brown plumes that can be seen from space.
So, this idea of dumping a bit or iron in hte oceans to get the plankton growing. So called “iron fertilisation”. In order to such some CO2 out as geoengineering.
Of course, we can’t do that as that would be unnatural.
