Dr Peter Ridd on the Greatest Mysteries of Climate Change

Written by Dr. Peter Ridd on September 3, 2025. Posted in Current News

The “Greatest Mysteries of Climate Change” video from Reef Rebels dives into the fascinating and perplexing aspects of climate change—those “mysteries” scientists are still trying to understand. Presented by Dr Peter Ridd.

Dr Ridd has been researching the Great Barrier Reef and other things since 1984, has invented a range of advanced scientific instrumentation, and has written over 100 scientific publications. Since being fired by James Cook University for raising concerns about science quality assurance issues, Peter Ridd receives no payment for any of the work he does.

Key Themes & Insights

• Framing the Question
  It begins by setting the stage: climate change isn’t just about warming temperatures—there are deeper, less well-known puzzles that demand our attention.YouTube+1

• Scientific Unknowns
  While specifics aren’t revealed in the available summary, the video explores complex phenomena such as:

  • The mechanisms behind erratic global climate patterns.

  • Surprising feedback loops or “tipping points” that could accelerate change.

  • Regional climate anomalies—places showing unexpected resilience or vulnerability.

  • The role of lesser-understood systems like deep-ocean currents, permafrost thaw, or aerosol effects.

• Call to Curiosity
  The tone encourages viewers to appreciate that even with extensive climate research, many foundational questions remain open. Understanding these “mysteries” is crucial for predictive climate modeling and shaping effective policy.

Peter Vincent Ridd is an Australian physicist, marine geophysicist, and author. He completed both his BSc (1978) and PhD in Physics (1980) at James Cook University (JCU) in North Queensland, Australia. Ridd served as Head of the Physics Department at JCU from 2009 to 2016 and led its Marine Geophysical Laboratory for around 15 years Wikipedia. His research focused on diverse topics, including ocean currents, sediment movement, coastal oceanography, and the development of instrumentation relevant to reef systems. He leads or contributes to media and communication platforms such as the Reef Rebels YouTube channel and has also been affiliated with the Australian Environment Foundation and contributed to the Institute of Public Affairs (IPA) via writings and lectures, IPA – The Voice For Freedom+1.
