WASHINGTON – El Niño, a powerful climate phenomenon, has emerged in a warmer Pacific Ocean and is on track to become one of the strongest ever recorded, according to meteorologists.
Experts warn that this natural cycle of warming will intensify the already concerning impacts of climate change, leading to more extreme weather events worldwide. The current El Niño is projected to rival or even surpass the record-setting event of 1997, which caused significant damage through heat waves, floods, droughts, and wildfires.

The U.S. National Oceanic and Atmospheric Administration (NOAA) has confirmed the presence of El Niño, a phenomenon that significantly affects global weather patterns. NOAA’s recent announcement indicates a 63% chance that this El Niño will reach such intensity this fall and winter that it could rank among the largest in history, dating back to 1950.
According to climate scientist Abby Frazier from Clark University, the warm waters associated with El Niño release heat into the atmosphere, leading to a surge in extreme weather events across various regions. She emphasizes that the situation, particularly in the Pacific, can escalate rapidly.
United Nations Secretary-General António Guterres has characterized El Niño as a pressing climate warning, stating, “El Niño conditions will pour fuel on the fire of a warming world.”
Regional Impacts of El Niño
The effects of El Niño vary by location. In the Atlantic, it typically reduces hurricane activity, but the opposite occurs in the Pacific, where the risk of hurricanes increases. This means while the U.S. East and Gulf coasts might see less hurricane activity, places like Hawaii may face greater threats.
For regions like the drought-stricken Middle East, El Niño may bring some relief. However, others may face increased challenges; for instance, western South America often experiences heavy rains and flooding during El Niño events. Countries like India could see intensified heat waves, while Australia might suffer from droughts and wildfires.
Northeastern Africa is likely to experience dramatic weather fluctuations, from intense drought to heavy rain, according to Columbia University climate expert Muhammad Azhar Ehsan.
In the U.S., El Niño can lead to more severe storms and increased rainfall in the southern states, yet it generally benefits the agricultural sector. Jon Gottschalck from NOAA’s Climate Prediction Center notes that conditions for crops like soybeans appear favorable in many key growing states, although dairy and cattle farming may experience mixed results.
The northern Rockies and Southwest regions, currently facing significant snow drought, may benefit from strong summer rains. Typically, the most substantial effects of El Niño in the U.S. occur during winter, with the southern states becoming wetter while the Pacific Northwest experiences warmer, drier conditions.
However, warmer temperatures associated with El Niño can hinder U.S. economic growth, as noted by Stanford climate economist Marshall Burke. Some scientists predict that 2027 could become the hottest year on record due to the lingering effects of this El Niño, which is expected to peak in the fall or winter.
Burke states, “We have pretty clear evidence that the U.S. economy grows more slowly when temperatures are above normal.”
What to Expect from the Current El Niño
The timing of El Niño’s development significantly influences its weather extremes. Typically, these events form in summer, peak in late fall or early winter, and diminish by the following spring. However, Ehsan’s team forecasts that the current El Niño might peak earlier than usual based on robust early indicators observed in recent weeks.
Princeton University climate scientist Gabriel Vecchi notes that significant El Niño events tend to have longer durations. The early signs of this El Niño, including the noticeable rise of warm water to the Pacific surface, have led forecasters to agree on the likelihood of an exceptionally strong event.
With climate change expected to contribute to stronger El Niños, experts like Frazier caution that it is still early to determine if the current event is a direct result of global warming.
Even before its official formation, this El Niño has garnered nicknames like “super” and “Godzilla.” Columbia’s Ehsan encourages a proactive approach, stating, “Instead of scared, we can ask people to be prepared.”
