That's the point, isn't it? Depending on the many assumptions and analytic techniques used, significance can be demonstrated for and/or against damn-near any phenomenon of nature. That is why peer review plays such a critical role at this time. Somebody has to understand the implications of the assumptions and analyses and these data are so complex than it generally takes an expert to understand the problem and methods.
Most of the time scientists wish to do the right thing. But just like real people, they may also be pushed by their own beliefs and prejudices. Again, this is where the peer review process, over the long-term, plays a moderating and corrective role.
There is no doubt that Man's understanding of climatology and the underlying physico-chemical processes and the contemporary and fossil records are better understood every month. This advancement is accelerating -- the rate of increase of knowledge is itself increasing. This seems likely to continue for the foreseeable future. This means that we know more than we did ten years ago and that we will know far more than that over the course of the next ten years.
In the past 10 years climatologists and ecologists have increasingly come to greater accord concerning global warming. There are very, very few knowledgeable scientists to dispute that the climate is warming. It is not perfect unanimity (few things in science are unanimously accepted), but it is undeniably the paradigm de jour. It will take a hell of a lot of extremely compelling contrary evidence to shift scientific opinion to an alternative view.
The argument is now centering on the degree to which man is creating or enhancing the warming trend and the degree to which intervention may ameliorate that warming trend. There is less accord on that, but it is continues approaching consensus. I'm betting within 5 years that we will know to a great degree of reliability, the degree to which Man may influence the climate.
