Climate change in Nebraska
Climate change in Nebraska encompasses the effects of climate change, attributed to man-made increases in atmospheric carbon dioxide, in the U.S. state of Nebraska.
The University of Nebraska–Lincoln (UNL) reported that "climate change poses significant risks to Nebraska's economy, environment and citizens". This view is expanded upon by the United States Environmental Protection Agency:
"Nebraska's climate is changing. In the past century, most of the state has warmed by at least one degree (F). The soil is becoming drier, and rainstorms are becoming more intense. In the coming decades, flooding is likely to increase, yet summers are likely to become increasingly hot and dry, which would reduce yields of some crops, require farmers to use more water, and amplify some risks to human health". The UNL report similarly identifies the main concerns for climate change in Nebraska as "increases in temperatures and the number of flooding and drought incidents".
The 2019 Midwestern U.S. floods left extensive damage in the state.
"Changing the climate is likely to increase the demand for water but make it less available. Soils will probably continue to become drier, because warmer temperatures increase evaporation and water use by plants, and average rainfall during summer is likely to decrease. More evaporation and less rainfall would reduce the average flow of rivers and streams. Decreased river flows can create problems for navigation, recreation, public water supplies, and electric power generation. Commercial navigation can be suspended during droughts (or floods) when there is too little water to keep channels deep enough for barge traffic. Decreased river flows can also lower the water level in lakes and reservoirs, which may limit municipal water supplies and impair swimming, fishing, and other recreational activities.
Lower flows during a summer drought can reduce hydroelectric power generation at a time of year when warmer temperatures increase the demand for electricity for air conditioning. Conventional power plants also need adequate water for cooling".
"Higher temperatures and drier soils are likely to increase the use of water by more than 25 percent during the next 50 years, mostly because of increased irrigation. Approximately one-third of the farmland in Nebraska is irrigated with ground water, most of which comes from the High Plains Aquifer System, and municipal water supplies also reply primarily on ground water. In Nebraska, the aquifer is only being depleted in a few western areas. But water levels are declining throughout much of Kansas, where the average temperature today is similar to what the average temperature of Nebraska is likely to be 70 to 100 years from now".
"Rising temperatures and changes in rainfall are likely to have both negative and positive effects on Nebraska’s farms and ranches. Hot weather causes cows to eat less and grow more slowly, and it can threaten their health. Increased winter and spring precipitation could leave some fields too wet to plant, and warmer winters may promote the growth of weeds and pests. Hotter summers and drier soils would cause droughts to become more intense. Over the next 70 years, the number of days per year above 100°F is likely to double.
