El Niño is the periodic warming of central and eastern tropical Pacific waters. The last El Niño occurred in 2009, Ortiz said, and its impact was felt in the United States with flooding in the south and wildfires in California. The research team looked at El Niño-Southern Oscillation (which is often just called El Niño), reconstructing sea surface temperature of the equatorial Pacific over the past 14,000 years.
