Two years ago an Oregon science teacher produced a video called "The Most Terrifying Video You'll Ever See." Greg Craven's schoolroom lecture on how to think about global warming and decide whether action against it is needed became an internet hit with over seven million viewings.
Craven has now turned the movie into a book (isn't it usually the other way around?) called "What's The Worst That Could Happen? A Rational Response to The Climate Change Debate."
Craven uses tools of risk assessment to help us decide how to think about and approach this issue. The focus is not on what to think about global warming, but how. The graphic above is adapted from his book, and summarizes the core argument: He sees this as a choice between action and no action against something that is true or false.
If you see global warming as false, we do nothing against it, and nothing happens, then we can "Party!" On the other hand if you see it as false, we do nothing, and all the scientific projections come to pass, then "Global Catastrophe" is our future.
As Craven points out, taking action against global warming comes with significant costs, but is less expensive than "Global Catastrophe." This is all about making choices and living with consequences.
