Ancient shellfish remains rewrite 10,000-year history of El Nino cycles

8 agosto 2014

Piles of ancient shells provide the first reliable long-term record for the powerful driver of year-to-year climate changes. Results show that the El Niños 10,000 years ago were as strong and frequent as they are today. The study results question how well computer models can reproduce historical El Niño cycles, or predict how they could change under future climates.
