Dust Bowl II?

Researchers at the Lamont-Doherty Earth Observatory and NASA Goddard Institute for Space Studies raise concerns that climate change and population growth could cause conditions similar to the Dust Bowl crisis of the 1930s. Climate modelers discovered that although the U.S. Great Plains had experienced similar weather patterns in years past, it was actually the dust raised by agriculture that provided a tipping point to disaster. The researchers estimate that farm dust probably doubled the drop in rainfall and increased the range of the drought into major farming regions. With global-warming-fueled droughts and floods being predicted in the coming years, this study offers a glimpse into how human interaction with even normal natural fluctuations can create unexpected and disastrous results.
