Scientific study finds El Nino events have become significantly more intense

Researchers from the University of Michigan have determined that El Nino climate events have increased in strength by nearly 40% over the last 40 years compared to the pre-industrial era. The study, published in the journal Science, utilized chemical analysis of coral cores from the Galapagos Islands and climate models spanning the last millennium to assess historical temperature variations in the tropical Pacific.

The investigation revealed that the intensity of El Nino events observed in the past 40 to 50 years exceeds any recorded in the previous 1,000 years. Scientists suggest this shift coincides with the period when human activity began impacting the global climate through greenhouse gas emissions, noting that no historical period shows such heightened intensity as the modern era.
