El Nino and La Nina
El Niño and La Niña are parts of an oscillation in the ocean-atmosphere system (called the El Niño Southern Oscillation, or ENSO cycle) that can impact weather and climate conditions across the globe. El Niño features warmer-than-average temperatures in the waters of the equatorial Pacific Ocean, while La Niña features colder-than-average waters. Read our stories below on the latest ENSO conditions and research into how the cycle affects global weather patterns.
Evidence is mounting against the so-called climate change hiatus — a period lasting from 1998 to 2012 — when global temperatures allegedly stopped rising as sharply as they had before.
This year's hurricane season is likely to be more active than usual, thanks to an absent El Niño and warmer tropical Atlantic Ocean waters.
Back-to-back hurricanes Matthew and Nicole may signal worse weather to come if La Niña climate conditions take hold across the globe, according to weather scientists.
