Popular science blogger Jo Nova and Emeritus Professor Aynsley Kellow explore the importance of the scientific process: what science is and isn’t, the decline of the peer-review process, and how far climate research has come from being science. They discuss what this means for policy making and what can be done, if anything, to fix the current state of play.

Emeritus Professor Aynsley Kellow of the University of Tasmania is an environmental policy specialist and explores the same themes in his chapter ‘Climate Science and Policy-based Evidence’ in Climate Change: The Facts 2020.
