Farming pushed natural drought into disaster--and could do so again.NEW YORK – Climate scientists using computer models to simulate the 1930s Dust Bowl on the U.S Great Plains have found that dust raised by farmers probably amplified and spread a natural drop in rainfall, turning an ordinary drying cycle into an agricultural collapse. The researchers say the study raises concern that current pressures on farmland from population growth and climate change could worsen current food crises by leading to similar events in other regions.
