Underscoring the divisiveness of climate change in American politics, government officials at Florida’s main environment agency have reportedly been asked to refrain from mentioning it.

Officials from the state’s Department of Environmental Protection (DEP) were given an unwritten order not to use the words climate change or global warming in any official communication or reports, the Florida Center for Investigative Reporting (FCIR) claimed on Sunday.

“We were told not to use the terms climate change, global warming or sustainability,” Christopher Byrd, an attorney in DEP’s Office of General Counsel from 2008 to 2013, told FCIR in an interview. “That message was communicated to me and my colleagues by our superiors in the Office of General Counsel.”

Other former DEP employees claimed to FCIR that the unwritten rule was implemented after Rick Scott, who has repeatedly denied climate change is the result of human activity, became governor of Florida in 2011.

The DEP denies that it has a policy on the matter.
