• Primary features
Continental climate type withhigh interannual variability.
East-west precipitation and humidity gradientwith wet and dry seasons.
Drought and flood are commonsometimes occurring in rapidsuccession.

Enhancement of the greenhouseeffect from human activityis resulting in the long-termtrend (warmer and wetter).

• Mitigation
Reduction of greenhouse gas emissions.
Increased efficiency and resource management.
Carbon sequestration and improvementsin soil health.
Integrating strips of native prairie vegetation into row crops has been shown to reduce sediment and nutrient loss from fields, as well as improve biodiversity and the
delivery of ecosystem services.33 Iowa State University’s STRIPS program is actively conducting
research into this agricultural conservation practice.https://nca2018.globalchange.gov/chapter/21/

Warmer by 4°F on average in 30 years, 9°F at the end of the century.Des Moines, IA Topeka, KS Stillwater, OK
Growing season 30 days longer.Double the number of 90°F days.
Wetter climate overall with seasonal shiftsWetter winter, spring; drier summer, wetter fall.
Punctuated by drought events.More heavy rain events.
