Scientists are usually reluctant to state anything as fact preferring instead to prequalify everything with the term "theory" (relativity, big bang, string, quantum entanglement....). However, while some theories prove to validate, others often sit on the lab bench for centuries waiting for that missing link. The one commonality is that they remain theories which means that they can and often are proved wrong. So why is it that climate change is a done deal?

Should we really believe that pretty much every scientist worth their weight in petri dishes agrees that climate change is fact? Professor Ian Plimer thinks not. Keith discussed this fascinating and controversial book with the author for the Australian Institute of Company Directors and you can listen to the podcast by clicking through here. After all shouldn't all Company Directors undertake due dilligence before spending the shareholders money? Whatever side of the climate change fence you sit on, this is a fascinating and thought provoking book.
