The World Meteorological Organization (WMO) has warned that the La Niña phenomenon could return between September and November 2025 , disrupting global weather patterns. This news is cause for concern because its effects are often extreme: torrential rains, floods, and, in other regions, devastating droughts.

La Niña is not a new phenomenon, but it is becoming increasingly intense due to climate change. The oceans are cooling in the equatorial Pacific, which alters atmospheric currents and, consequently, the climate in many regions. Agricultural countries like Brazil, India, and Mexico are already preparing for scenarios of crop losses, which will impact global food security.

The impacts are not only economic. When water is scarce, the most vulnerable communities are the first to suffer. And in these contexts, women often bear the greatest burden: caring for children, searching for food, and traveling miles to obtain drinking water.

The consequences also extend to public health. Severe droughts facilitate the spread of waterborne diseases, while floods destroy healthcare infrastructure and cause mass displacement. In an interconnected world, what happens on one continent quickly affects the others.

The WMO warning is not simply a weather forecast. It is a wake-up call about the need for action: investing in early warning systems, strengthening rural communities, supporting climate resilience, and, above all, recognizing that gender inequality is a determining factor in how climate crises affect populations.
