Jeffrey Shaman Predicts Record-Breaking El Niño Event Will Influence Global Weather Patterns Through 2027

Climate and public health researcher Jeffrey Shaman of Columbia University reports that an unusually intense El Niño event is gathering strength in the tropical Pacific. Computer models project this event to be one of the strongest since at least 1950, with an 81% chance of reaching "very strong" status by late fall. The administration announced that the stronger the El Niño signal, the more predictable the seasonal impacts will be, providing a crucial window for policymakers to prepare for extreme heat, droughts, and floods. In the United States, the event is expected to bring a milder winter to the northern tier and wetter conditions to the southern tier. While a stronger El Niño does not guarantee extreme weather in every location, it increases the likelihood of characteristic teleconnections. Experts suggest that the advanced notice of this intense cycle will allow cities and farmers to plan for potential water shortages and crop variations. The event is expected to continue intensifying through the end of 2026, potentially setting records for the warmest years on record.
