It probably never truly recovered from the Dust Bowl. Powell noted correctly that the western plains are dryin part because they lie in the rain shadow of the Rocky Mountains, which rake offalmost all the moisture blowing in from the Pacific Ocean. They noted that aridity will likely increase at all longitudes across the Great Plains and that the existing gradient will weaken, blurring the boundary between east and west.

Its going to be a real killer for the planet. It makes sense that warmer temperatures would contribute to more rapid evaporation thus encouraging the aridity moving eastward. One can literally step over the meridian line, but the boundary it represents is more gradual. Seager says year-to-yearweather variations mayblur the data, and so far thechanges arestill too small and gradual to yet affect land use over wide areas. Researchers became interested in how the 100th meridian affected population after noticing a world map of population density on which two sharp lines stood out: one running east-west along Africa's semi-arid Sahel to the south of the Sahara Desert, and the other the 100th meridian through North America.

In 2012, Richard Seager, a climate scientist at Columbia Universitys Lamont-Doherty Earth Observatory (LDEO), became interested in the 100th meridians significance after chancing upon a world map of population density on which two sharp lines stood out: one running east-west along Africas semi-arid Sahel to the south of the Sahara Desert, and the other the 100th meridian through North America.
