For five years, the Coral City Camera has given viewers a live look at aquatic reef life near Miami. It's documented the declining conditions and shown a surprising vitality among some coral species.

A group called Force Blue, which does conservation work across the country, is providing what they call "mission therapy" to veterans who miss the camaraderie and the sense of purpose of service.

Scientists working to save Florida’s ailing reef hope Caribbean coral thriving in hotter water could bring some relief.

The debris from Lahaina's fire contains toxic chemicals and sits right next to a coral reef. So the community is collaborating with scientists to track water quality.

Climate change is heating oceans faster than the world's coral reefs can handle. So scientists are breeding corals that can withstand hotter temperatures – but only to a point.

Coral reefs face a dire future as oceans get hotter. Scientists are breeding corals that can handle heat better, in the hope they can survive long enough for humans to rein in climate change.

The pickle-shaped bottom feeders may reduce the amount of microbes on the seafloor that could potentially sicken coral, scientists suggest

As oceans get hotter, coral reefs are suffering. Scientists are working on ways to preserve coral by freezing and then reviving them to restore reefs someday.

There's little that separates the ocean from the 2,200 burned buildings in Lahaina. Officials are working to block runoff that could harm the coral reefs offshore.

A new study takes a comprehensive look at the plastic debris smothering reefs, where in the ocean it's more prevalent — and how to deal with the problem.

The wondrous findings of a global project to record the sound of ocean habitats threatened by climate change and pollution — then play it through loud speakers set up next to troubled reefs.

Hotter temperatures are threatening coral reefs worldwide. Now, scientists are pinpointing how some "super corals" are better able to withstand the heat.

The Earth has already warmed more than 1 degree Celsius. New research suggests that above 1.5 degrees, massive ice melt, ocean current disruptions and coral die-offs are likely.

Some corals have turned a ghostly white due to extreme heat stress. It's the fourth bleaching event on the Great Barrier Reef in the last seven years, which makes it harder to recover.

Despite new pledges to cut emissions, the world is not on track to hit a key climate change target of limiting warming. Scientists warn a planet that heats up more than that will look very different.
