Pondering the global warming debate in a paddock.....


I have been following the global warming debate with interest since being a farmer it will impact on me; I may have to fit phart retarders to all the cows for one thing since methane has been identified as a major greenhouse gas.

There are a few questions I would like answered to help me understand what is going on.

What should the temperature of the earth be?
Since the climate is a dynamic system and there have been many variations in temperature, ocean levels and the like over the last couple of million years - how do we definitely know that this change is not another natural change?

Do the models that are used to show global warming, when run backwards show the climate we know has been recorded?
This is important in that the models should be based in what is known and work to the unknown. Once you put in the variables and run the models forward to predict global warming, if you add the same variables and run the model backwards do the models show the climate that we have records for?

The Earth's climate is a very complex system - do we have enough knowledge of these systems and how they interrelate to identify specific global warming causes?
Even if the final out come is that global warming theory is fault ridden and sloppy science, I have come to the conclusion that the development of sustainable energy should be encouraged.
It is not wise to be so reliant on fossil and mineral resources for our major energy needs.

That old farmyard saying comes to mind, “don’t put all your eggs in the same basket.”

That is a question I always wonder about.
