Oceans' Role in Climate - Jason-1

Changing conditions in the Pacific have stirred up Earth’s largest ocean and redistributed its heat, piling up warm waters along U.S. Western shores and raising sea level in the process.

El Niño is characterized by unusually warm ocean temperatures in the eastern equatorial Pacific. The warmer water associated with El Niño displaces colder water in the upper layer of the ocean caus...

Estudio de seguimiento de la altura de los océanos para comprender el clima terrestre

Earth’s rising seas are some of the most visible signs of our warming planet. Over the last 23 years, NASA satellite missions have observed a steady rise in global sea levels as polar ice sheets me...

Global sea level rise is accelerating incrementally over time rather than increasing at a steady rate, as previously thought, according to a new study based on 25 years of NASA and European satelli...
