Greg Craven's book What's The Worst That Could Happen? A Rational Response To The CLimate Change Debate in my opinion is the best book yet written on the debate of global warming and climate change.

Regardless of which side you're on in the debate, those who don't believe it will be a problem and are worrying about the economic impacts that will happen if we make drastic changes. Or if you're on the side of the activists who believe that global warming is as great a threat to life on the planet as nuclear weapons or an asteroid hitting the planet.

One problem is that a lot of people are tired of the debate and just want it settled one way or the other, take action or don't take action and lets get on with our lives.

Another problem that must be taken into consideration is that regardless of what side you believe anyone could be wrong.

Greg Craven's book gives you thinking tools to help you bypass the need to decide which side is right and which side is wrong.

The book among other things asks you to consider these scenarios:

1. If we needed to take action and didn't. What are the consequences?
2. If we needed to take action and did. What are the consequences?
3. If we didn't need to take action and didn't. What are the consequences?
4. If we didn't need to take action and did. What are the consequences?

Imagine a best case and worst case scenario for each of those scenarios.

Scenario one: The consequences are devastating, coastal communities are ravaged and no real best case scenario that I can think of.

Scenario two: Worst case scenario - high economic costs such as increases gas prices and utility bills. Best case scenario we avoided disaster.

Scenario three: Status quo. We all continue to party like there's no tomorrow reading up on the exploits of celebrities.

Scenario four: Worst case scenario - a global economic depression. Best case scenario we have fully developed alternative energy sources and are no longer dependent on unstable regions and governments for oil.

Being of libertarian leanings I tend to be leery of anyone who thinks they get to tell people how to live and how to think.

Libertarianism however is "everyone has the right to live as they choose as long as they are not deliberately bringing aggression towards other people. If they are inadvertently bringing aggression then you must take steps to correct it."

It would seem to me that the way we have been living is inadvertently bringing aggression towards the planet and we must therefore take steps to correct it.

The book is highly recommended for anyone still sitting on the fence of the global warming debate.
