(Newser) – The Department of Homeland Security is hoping that weather-altering techniques can lessen the devastation caused by hurricanes, the Daily Telegraph reports. A hurricane reduction program likely to begin in October will devote $64 million to efforts such as spreading tiny salt particles in the storms to drain them of much of their rain before they hit land.

Another idea is to place a layer of oil on the ocean in a storm’s path to cut evaporation from the sea, keeping the hurricane from getting too hot and thus more powerful. But weather’s mechanisms are poorly understood, and critics fear unintended consequences.
