A strong El Niño could have widespread humanitarian and environmental impacts. It may lead to extreme weather events such as droughts, floods, and heatwaves, disrupting agriculture, water supplies, and ecosystems. Vulnerable regions, particularly in the Global South, could face severe food and water insecurity. Additionally, the warming trend could exacerbate existing climate challenges, including rising sea levels and biodiversity loss. The potential for 2027 to become the warmest year on record underscores the urgency of global climate adaptation and mitigation efforts.
