Science or silence? My battle to question doomsayers about the Great Barrier Reef

The only problem is that it isn't so. The Great Barrier Reef is in fact in excellent condition. It certainly goes through periods of destruction where huge areas of coral are killed from hurricanes, starfish plagues and coral bleaching. However, it largely regrows within a decade to its former glory. Some parts of the southern reef, for example, have seen a tripling of coral in six years after they were devastated by a particularly severe cyclone.

Reefs have similarities to Australian forests, which require periodic bushfires. It looks terrible after the bushfire, but the forests always regrow. The ecosystem has evolved with these cycles of death and regrowth.

The conflicting realities of the Great Barrier Reef point to a deeper problem. In science, consensus is not the same thing as truth. But consensus has come to play a controlling role in many areas of modern science. And if you go against the consensus you can suffer unpleasant consequences.

The main system of science quality control is called peer review. Nowadays, it usually takes the form of a couple of anonymous reviewing scientists having a quick check over the work of a colleague in the field.

Peer review is commonly understood as painstaking re-examination by highly qualified experts in academia that acts as a real check on mistaken work. It isn't. In the real world, peer review is often cursory and not always even knowledgeable. It might take reviewers only a morning to do.

Scientific results are rarely reanalyzed and experiments are not replicated. The types of checks that would be routine in private industry are just not done.

I have asked the question: Is this good enough quality control to make environmental decisions worth billions of dollars that are now adversely affecting every major industry in northeast Australia?

Our sugar industry has been told to make dramatic reductions in fertilizer application, potentially reducing productivity; our ports have dredging restrictions that threaten their productivity; scientists demand that coal mines be closed; and tourists are scared away because the reef is supposedly almost dead – not worth seeing anymore.

Last August I made this point on Sky News in Australia in promotion of a chapter I wrote in "Climate Change: The Facts 2017," published by the Australian free market think tank the Institute of Public Affairs.

"The basic problem is that we can no longer trust the scientific organizations like the Australian Institute of Marine Science, even things like the Australian Research Council Centre of Excellence for Coral Reef Studies … the science is coming out not properly checked, tested or replicated and this is a great shame because we really need to be able to trust our scientific institutions and the fact is I do not think we can any more," I said.

The response to these comments by my employer, James Cook University, was extraordinary.

Rather than measured argument, I was hit with a charge of academic serious misconduct for not being "collegial."
