Short Essay On The Dust Bowl Argumentative Essay Help

First we ran a small ensemble of simulations with the atmosphere model forced by 1920s sea surface temperatures (SSTs) to act as our base of comparison for the simulated 1930s.Next we created a small ensemble of simulations with the model forced by 1930s SSTs.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?More soil was lost by wind erosion than the Mississippi carried to the sea.Although the numbers are not known, hundreds if not thousands of Plains residents died from 'dust pneumonia', a euphemism for clogging of the lungs with dirt.

Much of the Plains had been plowed up in the decades before the 1930s as wheat cropping expanded west.

There had never been dust storms like these in prior droughts.

In the worst years of the 1930s on as many as a quarter of the days dust reduced visibility to less than a mile.

For model experiments, anomalies are relative to the SST forcing (1920-1929) experiment.

Plots for the GHCN anomalies are based on 10 years (1920-1929) and 8 years (1932-1939); for the model output, each plot represents output from five member ensembles simulations; 50 years for 1920-1929 and 40 years for 1932-1939.

  1. PS04 used the concept of a "stabilization wedge", in which "a wedge represents an activity that reduces emissions to the atmosphere that starts at zero today and increases linearly until it accounts for 1 Gt C/year of reduced carbon emissions in 50 years." Implementing seven such wedges would achieve sufficient GHG emissions reductions to stabilize atmospheric carbon dioxide at 500 ppm by 2050, and emissions would have to decrease linearly during the second half of the 21st century.
