The Great Barrier: an announced dead

greatbarrie

Higher water temperatures in 2016 caused the worst destruction of corals ever recorded on Australia’s Great Barrier Reef, a study has found.

Some 67% of corals died in the reef’s worst-hit northern section, reports the BBC

The situation was better in the central section, where 6% perished, while the southern reef is in good health.

But scientists warn recovery could be difficult if climate change continues.

Coral bleaching happens when water temperatures rise for a sustained period of time.

In February, March and April, sea surface temperatures across the Great Barrier Reef were the hottest on record, at least 1C higher than the monthly average.
