Satellites are keeping a close eye on a phenomenon brewing in the Pacific Ocean.

The waters near South America’s west coast are getting warmer. Satellites like Sentinel-6 Michael Freilich, a collaboration between Europe and the U.S., know this because the sea level there has amplified; warm stuff expands, and cold stuff contracts. Rising surface ocean temperatures in the central-eastern Pacific then have a cascading effect on weather patterns in Asia and North America. It’s called El Niño.

OnePlus is releasing its first foldable phone, the OnePlus Open, on October 26 for $1,699. The book-style foldable phone is a direct shot at Samsung's $1,799 Galaxy Z Fold 5.
