Acadia National ParkMaine2025/09/202025-09-20: WP aticle reported removed signs that make reference to climate change. "Rep. Chellie Pingree (D-Maine) said that signs removed from Acadia — which sits on an island famous for Cadillac Mountain, where the rising sun first hits the United States each day — referenced climate change’s role in extreme weather that has caused millions of dollars in damage to the park. Those impacts include sea-level rise, storm surge and extreme rains, she said.
Signage suggesting visitors take a shuttle bus to minimize their carbon footprint was also taken down, according to Pingree."

2025-09-29 update: MainePublic.org reports 10 signs at Acadia have been removed, "six on the summit of Cadillac Mountain, and four in the Great Meadow. The informational blurbs had asked hikers to help protect the fragile ecosystem by staying on trails and not picking berries, detailed how rising seas and intense storms due to climate change impact the park, and encouraged visitors to help avoid emissions by using the park's Island Explorer bus. Others explained the cultural and spiritual significance of Cadillac Mountain for the Wabanaki people."

Gateway National Recreation AreaJamaica Bay Wildlife RefugeNew York City, NY2025/09/20"a display at Jamaica Bay Wildlife Refuge in New York City was taken down for making reference to historical events like slavery, Japanese internment camps and conflicts with Native Americans in describing the park system, according to two people familiar with the matter and photos reviewed by The Post. “Some very new parks preserve not just lands or buildings but our nation’s ideas and ideals. They remind us of things we hope to live up to — like women’s rights and liberty — and things we hope never to repeat — like slavery, massacres of Indians, or holding Japanese Americans in wartime camps,” the display said, prior to its removal."yeshttps://www.washingtonpost.com/climate-environment/2025/09/20/national-parks-climate-change-slavery-purge/no
