illuminem summarises for you the essential news of the day, reviewed by our editorial team. Read the full piece on CNN or enjoy below:

🗞️ Driving the news: El Niño has crossed into "very strong" territory, with NOAA's Relative Oceanic Niño Index reaching 2.0°C above average, the highest official category, informally called "super"
• It is the strongest event on record for this date and NOAA puts a 75% chance on it peaking as the strongest since records began in 1950

🔭 The context: A weak La Niña was in place a year ago; only a handful of years have flipped this rapidly, including the 1982-83 event
• Effects are already visible: extreme wind shear has produced a record-long wait for the Atlantic's first hurricane, while the Pacific has generated sixteen storms including two Category 5 hurricanes, with Hawaii facing three tropical systems in under a month
• Indonesia's wildfires are burning through conditions El Niño made unusually dry.

🌍 Why it matters for the planet: This event is unfolding in a materially hotter ocean than any previous record El Niño, and the measurement itself has changed to account for it
• The cycle raises global air temperatures on top of that baseline, which contributed to August being Earth's hottest month on record and could begin a stretch culminating in a record-hot 2027

⏭️ What's next: El Niño typically peaks in winter, when its influence on global weather is most pronounced
• The East Pacific has already produced fourteen storms with two and a half months of season remaining, likely to exceed its seasonal average of fifteen. Indonesian fire conditions could deteriorate further

📈 One stat: A 75% chance of this becoming the strongest El Niño since records began in 1950
