Unfortunately Clayton, we will all agree on it someday. When the factors become so evident that they affect our everyday lives, we will have to agree. We will definitely see more acute weather in our lifetimes, it's interesting to look at the storm data for the past 100 years.

Changes in data are pretty fine right now and it takes some knowledge of science to understand them. CO2 ppm in the atmosphere is definitely up (no refuting that), which is most definitely caused by humans (again , no argument), which in turn is responsible for the climatic changes (there's where people have a hard time).

In the myopic world of our everyday lives we can see very little change right now, which is why it's a difficult for non-scientists to 'believe'.

It's the same reason that people refused to believe the Earth is round. "It doesn't look round from where I stand".

It's definitely going to be interesting to see what happens.

BTW Australia just committed to sign the Kyoto Protocol leaving the U.S. the last industrialized hold out. Is it that we are smarter than everybody? I'm not so sure.
