Trump Wants to Downplay Global Warming. Louisiana Won’t Let Him

On a recent morning in Baton Rouge, a thousand miles from where Senate Democrats were jousting with Donald Trump’s nominee to run the U.S. Environmental Protection Agency about whether humans are warming the planet, the future of U.S. climate policy was being crafted in a small room in the east wing of the Louisiana Capitol. The state’s 7,700-mile shoreline is disappearing at the fastest rate in the country. Officials had gathered to consider a method of deciding which communities to save—and which to abandon to the Gulf of Mexico.

Bren Haase, chief of planning for the Coastal Protection and Restoration Authority (CPRA), was presenting his team’s updated Coastal Master Plan. Five years in the making and comprising 6,000 pages of text and appendices, the document details $50 billion in investments over five decades in ridges, barrier islands, and marsh creation. Tucked into the plan was a number whose significance surpasses all others: 14 feet, the height beyond which Haase’s agency has concluded homes couldn’t feasibly be elevated.
