The resurgence of El Niño poses risks to marine ecosystems, including fish and coral populations, due to rising ocean temperatures. Additionally, global weather patterns may experience disruptions, potentially leading to extreme weather events such as droughts, floods, and heatwaves in various regions. The severity of these impacts will depend on the strength of the El Niño, which is currently projected to be strong or very strong by late 2026. Vulnerable communities and industries reliant on stable weather and ocean conditions may face significant challenges.
