- Global temperatures typically increase during an El Niño episode, and fall during La Niña. El Niño means warmer water spreads further, and stays closer to the surface. This releases more heat into the atmosphere, creating wetter and warmer air.

2 days ago · Modern El Niños occur intermittently every 2 to 7 years and typically last 9 to 12 months, but they may have persisted for ~3 Myr in the Pliocene . Many features of future El Niños simulated by Climate Model Intercomparison Project 6 (CMIP6) models remain uncertain, but stronger El Niños with fast onset and slow decay will likely occur .

Apr 16, 2024 · The El Niño weather phase, which began in summer 2023, has now come to an end, the Australian Bureau of Meteorology says. It helped to boost global temperatures to record levels in recent...
This naturally occurring climate phase brings warmer weather throughout the globe and can increase the risk of extreme weather. This section explains how El Niño happens, and what affect it can have on global temperatures that are already rising due to human-caused climate change.
Jul 13, 2023 · El Niño is a naturally occurring phenomenon of periodic warming of sea surface temperatures in the central and eastern regions of the Pacific Ocean. La Niña is the opposite,...

ENSO is a cycle of warm El Niño and cool La Niña episodes that happen every few years in the tropical Pacific Ocean. It is the most dramatic year-to-year variation of the Earth’s climate system, affecting agriculture, public health, freshwater availability, power generation, and economic activity in the United States and around the globe. “This is ...
During El Niño, chances for drought increase across India, Indonesia and Australia and a large part of the Amazon, while the southern U.S. tends to see more precipitation. During La Niña, the pattern is effectively reversed, with wetter conditions for Indonesia, Australia and parts of the Amazon, and dry conditions in the southern tier of the U.S. ...
Antonietta Capotondi, a CIRESscientist working at NOAA’s Physical Sciences Laboratory, said in recent decades, scientists have come to appreciate how significantly ENSO impacts can vary from event to event. “No two El Niños or La Niñas are perfectly alike,” Capotondi said. “We’ve seen how diverse ENSO events can be. This diversity adds another degr...
El Niño and La Niña are the warm and cool phases of a recurring climate pattern across the tropical Pacific—the El Niño-Southern Oscillation, or “ENSO” for short. The pattern shifts back and forth irregularly every two to seven years, bringing predictable shifts in ocean surface temperature and disrupting the wind and rainfall patterns ...
Oct 15, 2021 · La Nina’s natural cooling of parts of the Pacific is the flip side of a warmer El Nino pattern and sets in motion changes to the world’s weather for months and sometimes years.
