Scientists had predicted that this summer would be a tough one for the reef. They feared that extreme heat would scorch the coral.

"This year reef temperatures have shown that temperatures for the majority of the Great Barrier Marine Park are below the long-term averages we see for this time of year," he said."This year reef temperatures have shown that temperatures for the majority of the Great Barrier Marine Park are below the long-term averages we see for this time of year," he said.

The future, however, still does not look good. The future, however, still does not look good. Researchers believe as the world's climate continues to change the bleaching of the coral will become increasingly common.
