The World Meteorological Organization (WMO) has warned that a stronger El Niño event is likely to develop in the coming months, increasing the risk of extreme heat, droughts, floods and other severe weather events across many parts of the world.

According to the agency, El Niño is a natural climate phenomenon that occurs when sea surface temperatures in the central and eastern Pacific Ocean become warmer than normal. While it is a recurring event, a strong El Niño can significantly influence global weather patterns and add to the warming caused by climate change.

The warning comes as Europe continues to face intense heatwaves. Officials say extreme temperatures have already claimed more than 3,700 lives across France, Belgium and the Netherlands.

France has recorded around 2,025 deaths, while Belgium has reported nearly 1,200 fatalities. In the Netherlands, at least 480 people have died due to heat-related conditions. Authorities have cautioned that the death toll could continue to rise as hot weather persists.

Spain has also been severely affected, with hundreds of people reported dead during the prolonged spell of extreme heat. Health authorities have urged residents, especially older adults and those with existing medical conditions, to avoid prolonged exposure to high temperatures and stay hydrated.

Climate experts say rising global temperatures are making heatwaves more frequent, longer and more intense. They warn that if a strong El Niño develops alongside ongoing climate change, many regions could experience record-breaking temperatures, increased pressure on water supplies, crop losses and a higher risk of wildfires over the next two years.
