On Thursday, the Iowa House approved legislation prohibiting attempts to manipulate the weather or climate within the state, sending House File 2640 forward on a party-line vote.
The bill would make it illegal to release chemicals, substances or devices into the atmosphere for the purpose of altering weather, temperature, climate, sunlight intensity or moisture levels in Iowa. Violations would be classified as a Class D felony, with additional civil penalties for corporations involved in such activities.
Supporters say the legislation is a necessary safeguard against emerging atmospheric manipulation technologies, while critics argue the proposal addresses a problem that does not currently exist.
During debate, lawmakers adopted an amendment clarifying that the legislation would not interfere with routine agricultural practices such as aerial crop spraying.
Republican State Rep. Sam Wengryn, who managed the bill on the House floor, explained that the change was designed to ensure Iowa’s farmers would not be affected.
Democrat State Rep. Ken Croken supported the amendment, saying it reflected a practical concern for Iowa’s agricultural industry.
“This amendment is based on support for our farmers and good science,” Croken said. “I recommend support for this amendment.”
While Croken backed the amendment, he ultimately opposed the legislation itself, arguing the proposal lacks a scientific basis and addresses no pressing issue facing Iowans.
“In the alternative, I believe this bill is not based in science or solves any particular problem of concern to the people of Iowa,” Croken said. “I recommend a no.”
All Republicans present voted yes. All Democrats present voted no. Fifteen state representatives were absent, including Democrats Lindasy James and Josh Turek, who are both seeking federal office.
The bill now moves to the Iowa Senate for consideration.
