Climate Change Impacts in South Dakota

The following points are taken from the petition filed in May. Click on each topic below for more information.

Average annual temperature in the Great Plains region of the United States has increased approximately 1.5 degrees (Fahrenheit) since 1960-1970. By the end of the current century, temperatures are expected to increase further, anywhere between 2.5 degrees with lowest CO2 emission models, to 13 degrees with highest CO2 emission models.

In the last century, weather Stations in Pierre, South Dakota have measured an increase in the local temperature of 1.6 degrees, and an increase in annual precipitation of 20%. By the year 2100, South Dakota is expected to experience a 10%-30% increase in annual precipitation, and a further increase in temperature of 3 degrees during the spring and summer months, and by 4 degrees in the fall and winter months.

The amount of precipitation received on wet or snowy days is projected to increase. With a warmer climate, it is predicted that the occurrence of seasonal flash floods will increase in the western part of South Dakota.
