El Nino swings more violently in the industrial age, compelling hard evidence says
El Ninos have become more intense in the industrial age, which stands to worsen storms, drought, and coral bleaching in El Nino years. 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. "What we're seeing in the last 50 years is outside any natural variability. It leaps off the baseline. Actually, we even see this for the entire period of the industrial age," said Kim Cobb, the study's principal investigator and professor in the Georgia Institute of Technology's School of Earth and Atmospheric Sciences. "There were three extremely strong El Nino-La Nina events in the 50-year period, but i...
