Data from Mombasa’s Blue pH Swim (News #161) directly shaped Kenya’s updated *National Climate Action Plan*, released on August 1, 2025. Swim-collected acidity readings from 12 coastal sites revealed alarming hotspots near industrial outfalls—prompting the Ministry of Environment to mandate real-time pH monitoring for all marine industries by 2026. Citizen science gave us what satellites couldn’t: granularity, said Dr. Salim Ali (KMFRI). Safaricom’s *Ocean Health Dashboard*, built from swim data, is now public. UNEP cited the swim as a gold standard for community-led climate monitoring. A second edition, with 1,000 swimmers, is planned for March 2026.
