🗞️ Driving the news: El Niño is forecast to intensify from August through October 2026, amplifying already record-breaking heat across Europe, Asia and North America alongside wildfires and heat domes.

🔭 The context: Cities across the globe have already logged all-time temperature records this summer, while wildfires have forced mass displacement in Europe

🌍 Why it matters for the planet: An intensifying El Niño stacks additional warming on top of a summer that is already breaking heat records across multiple continents, compounding wildfire risk, water stress and human displacement well beyond what either factor would cause alone.

⏭️ What's next: Forecasters expect the El Niño pattern to strengthen through October 2026, meaning the current heat and fire conditions are likely to persist or worsen over the coming months.

💬 One quote: "El Niño is not just on our doorstep — it is inside the house and turning up the heat" — UN Secretary-General António Guterres

📈 One stat: South Korea hit 108.5°F (42.5°C), Barcelona 105.3°F (40.7°C) and Salt Lake City 109°F (42.8°C) — all all-time records; more than 200,000 people were forced to flee homes in France due to wildfires
