A new study has found compelling evidence in the Pacific Ocean that the stronger El Ninos are part of a climate pattern that is new and strange.
It is the first known time that enough physical evidence spanning millennia has come together to allow researchers to say definitively that: El Ninos, La Ninas, and the climate phenomenon that drives them have become more extreme in the times of human-induced climate change.
"There were three extremely strong El Nino-La Nina events in the 50-year period, but it wasn't just these events.
The team found the industrial age ENSO swings to be 25% stronger than in the pre-industrial records.
She removed the record-setting 1997/1998 El Nino-La Nina and examined industrial age windows of time between 30 and 100 years long.
"Maybe El Nino can just enter a mode and get stuck in it for a millennium.".
