Conservative States Seek Billions to Brace for Disaster. (Just Don’t Call It Climate Change.)

Mr. Forbes called climate change “not that important a thing for an action plan,” and said that mostly leaving the phrase out of the document was not intentional. He said the purpose of the proposal was to demonstrate to the federal government that Louisiana knows what it wants to do with the money.

“Our governor has acknowledged on multiple occasions that we expect the flooding to be more frequent and worse in the future, not better,” Mr. Forbes said. “So we’ve got to have an adaptive process here that constantly makes us safer.”

Other states used their proposals to emphasize the centrality of climate change to the risks they face. “Climate change is a key overarching challenge which threatens to compound the extent and effects of hazards,” wrote officials in Florida, where Republicans control both legislative chambers and the governor’s office.

In North Carolina, which has a Democratic governor and a Republican-controlled Legislature, the proposal argued that the state was trying to anticipate “how a changing climate, extreme events, ecological degradation and their cascading effects will impact the needs of North Carolina’s vulnerable populations.”

Shana Udvardy, a climate resilience analyst with the Union of Concerned Scientists, said the failure to confront global warming made it more important for governments to at least call the problem by its name.

“We really need every single state, local and federal official to speak clearly,” Ms. Udvardy said. “The polls indicate that the majority of Americans understand that climate change is happening here and now.”

Others were more sympathetic. Marion McFadden, who preceded Mr. Gimont as head of disaster-recovery grants at HUD during the Obama administration, said the department was responding to the political realities in conservative states. She described the $16 billion grant program as “all about climate change,” but said some states would sooner refuse the money than admit that global warming is real.

“HUD is requiring them to be explicit about everything other than the concept that climate change is responsible,” said Ms. McFadden, who is now senior vice president for public policy at Enterprise Community Partners, which worked with states to meet the program’s requirements. Insistence on saying the words raises the risk “that they may walk away.”
