Australian scientists have discovered a massive detached coral reef in the Great Barrier Reef. It is the eighth detached reef discovered in the northern Great Barrier Reef and the first to be discovered in over 120 years.

Anyone who's tending a garden right now knows what extreme heat can do to plants. Heat is also a concern for an important form of underwater gardening: growing corals and "outplanting," or transplanting them to restore damaged reefs.

Coral reefs are often called the "rainforests of the sea" because they harbor some of the highest levels of biodiversity of any ecosystem in the world. But as sea temperatures rise, coral reef systems are suffering mass bleaching events, leading to widespread mortality. One way to try and restore coral reef systems is coral reef gardening or "outplanting," a method of growing coral fragments in a nursery and transferring them to ailing reef systems. But like naturally grown coral, it's hard to keep outplants alive, especially with climate change steadily raising global sea temperatures.

Viruses, pollution and warming ocean temperatures have plagued corals in recent years. The onslaught of abuse has caused mass bleaching events and threatened the long-term survival of many ocean species. While corals have little chance of surviving through a mass bleaching, a new study found that when corals turn a vibrant neon color, it's in a last-ditch effort to survive, as CBS News reported.

Six years ago, during a global coral bleaching event and after the Port of Miami was dredged, endangered corals on Florida's coral reef began rapidly wasting away and dying. Their "mystery killer," whose exact pathogen still remains unidentified, is referred to as the "Stony Coral Tissue Loss Disease" (SCTLD).

The Great Barrier Reef is in trouble. The Australian government is trying to buy its crown jewel some time, but is it willing to support what the reef needs most — a reduction in emissions?

Tropical coral reefs are at a critical tipping point, and we've pushed them there, scientists say. Climate change may now cause previously rare, devastating coral bleaching events to occur in tropical coral reefs around the globe on a 'near-annual' basis, reported The Guardian.

The Great Barrier Reef, a natural wonder that once teemed with life, just experienced a major coral bleaching event, according to scientists who conducted aerial surveys over hundreds of individual reefs, as The Guardian reported.
