1. Dividing line: The past, present and future of the 100th Meridian. In 1878, without benefit of the Landsat program, GPS or Google, and just a decade after the creation of the National Weather Service, John Wesley Powell first advanced the idea that the climatic boundary between the United States’ humid East and arid West lay along a line “about midway in the Great Plains” — almost exactly 100 degrees longitude west of the prime meridian in Greenwich, England. This line, the 100th meridian, runs from pole to pole and cuts through six U.S. states, forming a partial boundary between Oklahoma and Texas. The 100th meridian also corresponds roughly to the 600-meter elevation contour as the land rises from the Great Plains toward the Rockies.

2. 100th meridian: East-west divide between moist and arid parts of U.S. may be shifting. Nearly a century and a half after explorer John Wesley Powell zeroed in on the 100th meridian west as the dividing line between the humid east and arid west of the United States, researchers say he was right -- but that climate change is now moving the line eastward, into the traditionally fertile Midwest. The effects on U.S. farming and other pursuits could be huge. Now, 140 years later, scientists are looking again at the 100th meridian. In two just-published papers, they examine how it has played out in history so far, and what the future may hold. (Submitted on October 2, 2018, by Cosmos Mariner of Cape Canaveral, Florida.)
