All else being constant, Seager says, as the effective 100th meridian encroaches eastward, farmers will likely shift from corn to wheat, or other less water-intensive crops, as corn yields decrease and become less profitable. I suspect the argument will be that the evapotranspiration in summer will be much higher, but recent weather changes since 1970s in this area have been to the contrary (fewer high summer day temps, mostly higher night time lows). https://en.wikipedia.org/wiki/Great_Plains. For more insight into each stop along the route, our content is arranged by state. One can literally step over the meridian line, but the boundary it represents is more gradual.

In 1803 President Thomas Jefferson acquired this territory in what became known as the Louisiana Purchase. Furthersouth,shifts in wind patterns arecausing less rain to fall. They estimated potential evapotranspiration the amount of water the atmosphere could potentially extract from the surface from the land based on temperature, wind speed, solar radiation and relative humidity. Scientist went on top of of the Antarctic Ice sheet and drilled down 2 miles or 10, 560 feet to extract that ice and analys its ancient atmphere. I think older generations have given up on the notion that there will be land left for their grandchildren. Some current estimates predict the usefulness of the aquifer for agriculture to lessen and become useless, perhaps as soon as the early parts of the mid-21st century, leading some farmers to turn away from aquifer-irrigated agriculture. Farms are fewer, but bigger, reflecting the economics of less water and lower productivity. The population was 3,977 at the 2010 census.
