A coral reef in a remote part of the Pacific Ocean is coming back to life.

Researchers who've been making a trek for years to the Pacific nation of Kiribati say a reef there is teeming with fish and color again. The Coral Castles reef had been bleached by warmer, more acidic ocean water. It's part of a trend that's choking brilliant coral reefs all over the globe.

Here & Now’s Peter O’Dowd visited the researchers at the New England Aquarium to find out why the reef recovered.
