Professor Ridd reviews the latest data on the state of the world’s coral reefs, which is extremely encouraging, especially for the Great Barrier Reef, the largest single reef system, with record high coral cover in 2022. A brief explanation of “bleaching” is given, a brilliant adaptation for corals to cope with warming or cooling temperatures. Finally, a brief comment is made on the subject of academic freedom and the general problem of freedom of speech and thought in universities and on the associated collapse of intellectual rigour and he raises questions on our failing universities and science institutions.
Professor Peter Ridd is a geophysicist with over 100 publications and 35 years’ experience working on the Great Barrier Reef; he developed a wide range of world-first optical and electronic instruments for measuring environmental conditions near corals and other ecosystems. He was Professor of Physics at James Cook University in North Queensland for over a decade before being fired in 2018 for pointing out serious quality assurance issues in reef science. He challenged his dismissal by the University and won in principle in the High Court but eventually lost the case on appeal on a technicality. He now volunteers his time to the Institute of Public Affairs to improve quality assurance systems of “science” used by Australian governments to make environmental laws and regulations. He also runs the Reef-Rebels YouTube channel.
Also, near the end, a fine section on his problems with "scientific correctness" and what's ahead for science as a whole:
