Read here. Climate "scientists" pushing the human-induced global warming hysteria have predicted that modern global warming will soon change the ENSO climate pattern and all that will remain will be a permanent El Niño. The latest peer-reviewed research, however, doesn't support that prediction.
Ivany et al. analyzed fossilized clam remains from 50 million years ago that were located in the Antarctica region. The clams existed in a climate that was at least 10 degrees warmer than modern temperatures. By analyzing clam rings, the scientists were able to determine that during that significantly hotter period, the ENSO still retained its pattern of variation from El Niño to La Niña and back.
"The prevailing theory predicts that rising global temperatures could cause the ENSO to collapse, resulting in permanent El Niño conditions, which could have a major impact on socioeconomic and ecological systems worldwide..."The good news is that despite the very warm temperatures during the Eocene, the evidence from the clams and tree rings shows that the ENSO system was still active, oscillating between normal and El Niño years. That suggests that the same will be true in our future as the planet warms up again.” [Linda C. Ivany, Thomas Brey, Matthew Huber, Devin P. Buick, Bernd R Schöne 2011: Geophysical Research Letters]
