 How has the new Nebraska Sea changed the climate in America?
THE GREAT NEBRASKA SEA By ALLAN DANZIG It has happened a hundred times in the long history of Earth—and, sooner or later, will happen again! It was still a matter of academic interest when in the late '40s geologists speculated on the relationship between the Kiowa Fault and the Conchas Fault farther south, in New Mexico, and which followed the Pecos as far south as Texas. Nor was there much in the papers a few years later when it was suggested that the Niobrara Fault (just inside and roughly parallel to the eastern border of Wyoming) was a northerly extension of the Kiowa. It strikes us today as ironic that from the late '50s there was grave concern about the level of the water table throughout the entire area. Newspapers in the mountain states gave it a few inches on the front page; anything is news in late August. Only Joseph Schwartzberg, head geographer of the Department of the Interior, wondered if the disturbance might not be a settling of the Kiowa Fault. The dust volcano was on the face of it a more plausible theory. They found themselves on the scene of what was fast becoming the most violent and widespread earthquake North America—probably the world—has ever seen in historic times. To describe it in the simplest terms, land east of the Fault was settling, and at a precipitous rate. East, where sharp reports and muffled wheezes told of continued buckling and dropping, the earth trembled downward. At the rate things were going, there might be a new lake the entire length of El Paso and Pueblo Counties. By 16 September the landslip had crept down the Huerfano River past Cedarwood. Land west of the Fault was holding firm, though Denver had recorded several small tremors; everywhere east of the Fault, to almost twenty miles away, the now-familiar lurch and steady fall had already sent several thousand Coloradans scurrying for safety. As the Fault moved north and south, new areas quivered into unwelcome life. Virtually all east-west land communication was suspended and the President declared a national emergency. By 23 September the Fault was active well into Wyoming on the north, and rapidly approaching the border of New Mexico to the south. Tremendous fissures opened up perpendicular to the Fault, and a general subsidence of the land was noticeable well into Kansas and Nebraska. The western borders of these states, and soon of the Dakotas and Oklahoma as well, were slowly sinking.
 It's brought on much warmer, more tolerable weather.
 Because everything is now along a coastline, it's much cooler.  For most of the states, it's about the same.  It's much muggier in many places now, and unlivable in others.  It's brought on much warmer, more tolerable weather.
