Why the Reflecting Pool Is Full of Algae After Trump's Renovation Warm weather has fueled a bloom that US National Park Service workers are trying to kill using everything from hydrogen peroxide to nanobubbles ahead of July 4 celebrations. On Wednesday morning, workers poured hydrogen peroxide into the Lincoln Memorial Reflecting Pool in Washington, DC. The treatment is the latest attempt by the Interior Department to control an algae bloom that has turned the pool bright green, despite President Donald Trump's costly renovation to make it "American flag blue" in time for the nation's 250th anniversary . Hot temperatures and climate change are among the risk factors that could be driving the outbreak. The Trump administration spent more than $14 million to update the pool ahead of celebrations across the US capital .

Despite being declared the third-hottest year on record, 2025 was a relatively quiet year for climate disasters in the US. No major hurricanes made landfall, while the total number of acres burned in wildfires last year--a way of measuring the intensity of wildfire season --fell below the 10-year average. But starting this week, the West is experiencing what looks to be a record-breaking heat wave, while forecasting models predict that a strong El Niño event is likely to emerge later this year. These two unrelated phenomena could set the stage for a long stretch of unpredictable and extreme weather reaching into next year, compounding the effects of a climate that's getting hotter and hotter thanks to human activity. Beginning this week and heading into next, a massive ridge of high-pressure air will bring record-breaking temperatures to the American West.

In this episode of Uncanny Valley, we discuss the economics and environmental impacts of energy-hungry data centers and whether these facilities are sustainable in the age of AI.
