Climate Connection

Above Average Temperature  
Above average temperatures can negatively impact crop yields and introduce new pests and pathogens. There was an upward trend in annual temperature and especially night and winter temperatures across the Midwest. The frequency of extremely cold winters has decreased as most recent winters were much above average. Climate models simulate an increase in the annual temperature as well as throughout all seasons across the region. The number of day’s consecutive and singular days with temperature exceeding 95°F is projected to increase, too.
