A giant warm wave is crossing the Pacific, signaling an El Niño that could alter weather worldwide this year
Sea level data from a #satellite launched by #NASA and #Europe'an partners shows that a swell of warm water hundreds of miles wide has arrived in the #Pacific Ocean off the coast of South America, a sign that #ElNiño will likely emerge later in the year. Because water expands as it warms, a rise in elevation of an area of the #ocean indicates increasing ocean temperatures.
El Niños can cause heavy precipitation in some regions and deficits in others, influencing daily life and commerce around the world.
