Strongest El Nino Could Shake Global Weather

Scientists predict that a powerful El Nino may form mid‑year, possibly the most intense on record. This warming pulse in the equatorial Pacific can shift heat across the planet, making summers hotter and storms more severe. The World Meteorological Organization says the signal for an El Nino is clear, but spring forecasts are still uncertain. The warming of ocean layers rises to the surface, a key step in building an El Nino. El Ninos appear every two to seven years and last about nine to twelve months. The current conditions match the biggest events in history, suggesting a “super El Nino” could materialise.If the Pacific releases large amounts of heat, it can trigger extreme weather: stronger heat waves, severe droughts in some places, and heavier rainfall elsewhere. In the Atlantic, this heat can dampen hurricanes, leaving islands drier and fewer storms. Across the United States, summer temperatures may rise sharply, with more daily thunderstorms in the Southwest. The Amazon could face increased fire risk as forests weaken from drought and logging. While El Nino temporarily lifts global temperatures, the long‑term rise from fossil‑fuel emissions will continue. Scientists warn that the next few years could be highly variable, but overall warming remains a steady threat.
