This week’s On The Radio segment discusses the recently released Climate Change Assessment.

Transcript: In early December, the first draft of the 4th national climate change assessment was released.

This is the Iowa Environmental Focus.

The National Climate Change Assessment comes out every four years. The goal of the assessment is to update the scientific community’s understanding of climate change, and suggest solutions on how to adapt to these changes.

The two biggest issues highlighted in the statement that will affect Iowa are increases in humidity and temperature.

The temperature of the Gulf of Mexico is rising. This is creating warmer and moister water vapor which is being pushed to the Midwest because of high pressure from the east and low pressure from the west. The exaggerated northward flow of moisture to the Midwest is increasing precipitation, creating more overall humidity, and more extreme rainfall in the late spring and early summer.

The Midwest’s average temperature has gone up 1.2 degrees since 1990, and is predicted to have the highest temperature increase in the country by mid-century. This will create challenges for the pollination cycle for the crops, forest health, and other ecosystems.
