Global warming-fact or fiction and how do you propose we tackle it?

[Final-Fan]

One online source has this to say on the subject, Linkzmax:

"With regards to geological history, I don't believe there are any demonstrable contradictions to greenhouse theory to be found. What we do have is an unfortunate lack of comprehensive and well resolved data. There is always the chance that new data will turn up shortcomings in the models and new aspects to climate theory, and I guarantee you scientists in the field are working hard to uncover such things. Every scientist relishes the thought of uncovering new data that overturns current understanding. But I don't think that it makes any sense at all to reject CO2 as a primary driver of climate change today because it looks, through the foggy glasses of time, like CO2 has not always completely controled climate changes in the past.

"The climate system is complicated, even the configuration of the continents has a big effect, so you should not expect complete correlation between temperatures and any single factor throughout such a long and varied history."

So, for instance, the existence of Pangaea could have had a very different effect on the climate of its day compared to the separated continents of today. The continents were also smaller then. However, areas that ordinarily hold seas may have become cut off from the world ocean and dried up. This happened to the Mediterranean several million years ago and I imagine it could very well have affected global climate.
