A US federal appeals court in Boston has temporarily blocked a lower court ruling that required the Trump administration to reinstall dozens of exhibits removed from national parks, including displays on climate change and slavery. The decision, handed down on Thursday, 2 July, gives the administration continued leeway to remove signage it considers to cast the United States in a 'negative light'.
The legal battle began after President Donald Trump signed an executive order in 2024 directing the Interior Department to 'restore truth and sanity to American history' at national museums, parks, and landmarks. The order instructed officials to ensure that sites do not display elements that 'inappropriately disparage American past or living'. Interior Secretary Sough Burgum later ordered the removal of any 'improper partisan ideology'.
In response, a coalition of non-governmental organisations—including the National Parks Conservation Association (NPCA), the American Association for State and Local History, the Association of National Park Rangers, and the Union of Concerned Scientists—filed a lawsuit to halt the removals. In June, a district court judge sided with the groups, ordering the federal government to reinstall removed materials within 21 days. However, the appeals court this week argued that the lower court had erred in suggesting the removals would cause 'irreparable harm'—a key legal threshold for the injunction.
Removal of Climate and Slavery Exhibits
Among the affected sites is Acadia National Park in Maine, where physical signs informing visitors about the park's changing climate were removed in September 2025. The signs had detailed more frequent storms, intense rainfall, and rising temperatures linked to climate change. 'We have decades of scientific research that demonstrates the impact of climate change on Acadia National Park – longer droughts, more intense precipitation events, coastal storms, sea level rise,' Todd Martin of NPCA told reporters last year. 'The signs coming down at Acadia are just another example of erasure and censure that we’ve seen at our parks in recent weeks and months.'
The Interior Department also ordered the removal of a famous 1863 photograph titled 'Scourged Black' from at least one national park site. The image shows an enslaved man named Peter with severe whip scars on his back, serving as a stark historical record of slavery in the United States. Alan Spears, senior director of cultural resources at NPCA, said: 'National parks serve as living classrooms for our country, where science and history come to life for visitors. As Americans, we deserve national parks that tell stories of our country’s triumphs and heartbreaks alike. We can handle the truth.'
The Trump administration has framed the removals as a fight against 'ideological indoctrination'. The appeals court ruling now grants the administration free rein to continue removing signage it deems inappropriate, pending further legal proceedings.
The decision comes as the United States braces for extreme heat during the 4 July celebrations. New York Mayor Zohran Mamdani has advised residents to stay cool indoors, while in Hamptonburgh, multiple heat-related illnesses occurred after air conditioning failed on a bus carrying Junior Reserve Officers’ Training Corps cadets. Jeff Schlegelmilch, associate professor at Columbia University Climate School, noted that heat is one of the easiest phenomena to attribute to climate change. 'We have seen a continued increase in longer summers, hotter temperatures, hotter temperatures earlier on, more evaporation of moisture, higher humidity – effects like that,' he said.
The controversy over national park signage is part of a broader pattern of the Trump administration challenging established scientific and historical narratives. Meanwhile, European confidence in the United States has declined sharply, as reflected in a recent survey: European Confidence in US and Trump Plummets Ahead of July 4th Anniversary. In Europe, the debate over climate adaptation has taken centre stage, with Brussels shifting focus to resilience measures after a deadly heatwave: Brussels Shifts Focus to Climate Adaptation After Deadly Heatwave. The UK has also recorded its hottest June since 1884, intensifying climate concerns: England Records Hottest June Since 1884 as Heatwave Intensifies Climate Concerns.
The legal battle over the park exhibits is likely to continue, with the appeals court set to hear further arguments. For now, the Trump administration has secured a victory in its effort to reshape how American history and science are presented in public spaces.
