🗞️ Driving the news: Scientists warn the El Niño cycle could soon intensify, potentially pushing global temperatures beyond the critical 1.5°C threshold and triggering long-lasting climate disruptions

🔭 The context: El Niño is a natural ocean-atmosphere cycle in the tropical Pacific that releases vast amounts of stored heat into the atmosphere, reshaping global weather patterns
• A strong El Niño in the next 12–18 months could push average global temperatures to around 1.7°C above pre-industrial levels, amplifying existing warming trends
• Scientists warn that “super El Niño” events can trigger lasting “climate regime shifts,” intensifying floods in some regions while worsening heatwaves, droughts, and wildfires in others

🌍 Why it matters: A stronger El Niño on top of human-driven warming could accelerate climate instability and push ecosystems and societies beyond key thresholds
• Past events have already contributed to coral reef collapse, fisheries disruption, and extreme weather patterns that affect food and water security
• Climate “regime shifts” mean impacts may persist long after the event ends, turning short-term shocks into long-term risks for agriculture and infrastructure
• Scientists warn this could deepen the global adaptation gap, where countries are increasingly unprepared for the scale and speed of climate impacts

⏭️ What’s next: Governments and institutions may need to move from reactive responses to proactive, systemic adaptation strategies
• This includes redesigning infrastructure, agriculture, and water systems for a more volatile climate baseline rather than relying on historical norms
• Stronger El Niño events combined with global warming could create a feedback loop, making future climate disruptions more intense and persistent

📈 One stat: Global temperatures could reach about 1.7°C above pre-industrial levels during the next strong El Niño event
