Here's what to expect for the 2019 Atlantic hurricane season and how to get prepared.
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.
Australia's Great Barrier Reef corals are in trouble, with the northern part of the reef experiencing "the worst mass bleaching event in its history."
Hurricane Pali is the earliest ever recorded hurricane in the Central Pacific, a rare winter tropical cyclone that benefited from a strong El Niño.
A strong El Niño is brewing in the Pacific, which should bring warmer and wetter weather across the Southern and Eastern United States.
El Niño is expected to be more beast than "little boy" this year — a forecast about the weather pattern that becomes clear in newly released maps of the waters around the equatorial Pacific Ocean.
Snakebites in Costa Rica spike during El Niño and La Niña as venomous snakes respond to changes in the weather and climate.
No, El Niño is not the source of every weather crisis, but it can be devastating, and researchers have uncovered a new clue that may help predict how bad things can get.
