Prof Peter Ridd: the Great Barrier Reef recovers, our science institutions are failing us, science needs to be checked

Alan Jones, interviews Peter Ridd, James Cook university professor of physics about the state of the Great Barrier Reef

The coral reef recovers.

Peter Ridd: Coral Reefs recover — “the scientists make hay when it dies in a spectacular way but they are quiet when it recovers.”

On symbionts — “There is a large variety of symbionts and some allow coral to grow faster but are more sensitive to bleaching.”

All the corals on the Great Barrier Reef live and grow much faster in Papua New Guinea, Indonesia and Thailand where the water is much hotter than it is on the reef and the corals just juggle these symbionts. 4:20

Corals have a little thermometer built in them, when you take a core of them from many years ago we know what the temperature of the water was back when Captain Cook sailed up the coast, it was actually about the same temperature then. It was colder 100 years ago, but it has recovered from that. The temperatures on the reef are not even significantly warmer than average on a hundred year timescale.

Corals that bleach in one year will […]
