(ii) Man’s uncontrolled ambitions, greed and desire to conquer nature can lead to ecological disbalance and nature’s wrath.(iii) Technology and development should be nature friendly otherwise the very livelihood of mankind could be at stake.We have addressed this using the Goddard Institute for Space Studies atmosphere GCM which contains a dust module that can lift up dust from the surface, transport it in the atmosphere and allow it to interact with solar and longwave radiation transfer in the atmosphere.

It was the combination of drought and poor land use practice that created the environmental disaster.
Much of the Plains had been plowed up in the decades before the 1930s as wheat cropping expanded west.
Conversion of the Countryside in the USA from a Bread Basket to a Dust Bowl (19th Century) In early 19th century farmers in USA had uprooted all vegetation and used tractors to break the sod into dust.
When in early 1930’s when rains failed year after year and temperatures soared; winds blew with ferocious speed.
the Sahel) that dust can impact circulation and precipitation.
Second the Dust Bowl drought was unique in its spatial pattern - further north than is typical for a La Niña forced, or La Niña plus warm subtropical North Atlantic forced, drought. " Did the dust storms impact either the intensity of the drought or its area of impact?But the Dust Bowl drought was not meteorologically extreme by the standards of the Nineteenth and Twentieth Centuries.Indeed the 1856-65 drought may have involved a more severe drop in precipitation.For wonderful books on the topic see Worster (1979, Dust Bowl: The Southern Plains in the 1930s) and Egan (2006, The Worst Hard Time).But did the dust storms have a meteorological impact? First we know from studies elsewhere in the world (e.g.Here we have used the anomalies for each year in the observations and each year in the model run and for each of the 5 ensemble members.The boxes contain the one standard deviation spread of the anomalies and the whiskers bound the entire distribution.Alas, while natural prairie grasses can survive a drought the wheat that was planted could not and, when the precipitation fell, it shriveled and died exposing bare earth to the winds.This was the ultimate cause of the wind erosion and terrible dust storms that hit the Plains in the 1930s.The distribution for the 1920s is of course spread around zero. The combination of SST forcing and interactive dust forcing intensifies the drought.Box and whisker plots for precipitation anomalies, averaged over the central United States (30N-48N, 105W-85W).
