The Great Barrier Reef is unlikely to survive as more than a small, sad remnant of its past glory. The reason is straightforward. It is well known in climate science that even if we stopped harmful emissions tomorrow global warming would not peak for another several decades. By then most of the reef will be long gone.
This is not pleasant news, and clearly many would prefer it was not said, but there it is, the argument is simple and the conclusion is difficult to avoid.
