There is also debate among meteorologists about what effect the increased temperature would have. It's possible that it could result in increased cloud cover, which would reflect back more of the incoming solar radiation, which would then mean cooling. There are way to many variables.
The problem is climate change takes place over long periods of time. The year to year variations cannot determine a pattern.
In a nutshell, no one knows what's going to happen. What if we get another Krakatoa type volcanic eruption? All the human efforts to steady the climate would be wasted.
Never thought of it that way. Thanks!
The only thing is what about reports about the ozone layer in South America and Australia? Is it just hype or is it really happening that humans are starting to need to use more sunscreen etc to adapt to more UV radiation?

True, but we can't give up on something simply because 'bad things may corrupt our good things'. CO2 production is not the only way humans can affect an ecology, stripping forests can create deserts, deserts can change airflow and storm paths. Granted the Earth's weather patterns are complex systems thus making it very difficult to predict a specific outcome but we can generalize that certain human activities will cause weather patterns to 'tend' in a specific direction.
The cause of the global change is less important than our reaction to it. If we can affect a change we need to perform cost and risk analyses to determine if our current actions need to be changed.
