The proposed bill aims to prohibit geoengineering activities within the state of South Dakota. It establishes a new legal section that explicitly states that no person may engage in geoengineering, which is defined as the intentional, large-scale intervention in the Earth's climate system to counteract climate change. This includes actions such as removing carbon dioxide from the atmosphere or reflecting sunlight away from the Earth.

Additionally, the bill stipulates that any violation of this prohibition will be classified as a Class 6 felony, thereby imposing significant legal consequences for individuals or entities that attempt to engage in geoengineering practices within the state.
