NASA tracks changes to the planet with satellites and other scientific instruments. These include monitoring sea surface heights, sea surface temperatures, precipitation, and more. With these measurements, we can see the global impact of climate phenomena including El Niño and La Niña. What’s up with El Niño and climate change? Swipe through ➡️

Image Description (1/2):
Slide 1: In the background, a data map of sea surface temperature anomalies superimposed on a globe. Text on slide reads: What’s up with El Niño & climate change? Red arrows guide the reader to the next slide.
Slide 2: Black slide with a global temperature map. Text on slide reads: NASA reported that 2023 was the hottest year on record. That was fueled primarily by a long-term rise in human emissions of greenhouse gases. But warmer ocean temperatures from El Niño also added to the global temperature. We know because NASA satellites help us keep an eye on our changing planet. Red arrows guide the reader to the next slide.
Slide 3: Black background. A map of ocean temperature has a white border around it. Text on slide reads: The Breakdown: El Niño. Normally the winds blow from east to west across the tropical Pacific Ocean, which pushes warm water to the west. During El Niño, these winds weaken and the warm water moves back to the east. This results in warmer tropical waters in the central and eastern Pacific Ocean. Red arrows guide the reader to the next slide.
Slide 4: Black background. A map of ocean temperature has a white border around it. Text on slide reads: The Breakdown: La Niña. Sometimes the winds that normally blow from east to west in the tropical Pacific strengthen, pushing warm water to the west. Colder, deeper water then rises to the surface along South America’s Pacific coast. This results in cooler ocean waters known as La Niña. A red arrow guides the reader to the next slide.
