OK Pooey lets look into the details of one of your so called valid sites?
New Scientist Environment.
The hockey stick graph..

It is true that there are big uncertainties about the accuracy of all past temperature reconstructions, and that these uncertainties have sometimes been ignored or glossed over by those who have presented the hockey stick as evidence for global warming.

Preface to the article on climate warming.

Yet despite all the complexities, a firm and ever-growing body of evidence points to a clear picture: the world is warming, this warming is due to human activity increasing levels of greenhouse gases in the atmosphere, and if emissions continue unabated the warming will too, with increasingly serious consequences.

Does this show evidence of bias before the facts are prevented? It show me that the author was predisposed to believe in anthropogenic causes.

Chaotic influences..

Similarly, while we cannot predict the weather in a particular place and on a particular day in 100 years time, we can be sure that on average it will be far warmer if greenhouse gases continue to rise

Models

Most modellers accept that despite constant improvements over more than half a century, there are problems. They acknowledge, for instance, that one of the largest uncertainties in their models is how clouds will respond to climate change. Their predictions, which they prefer to call scenarios, usually come with generous error bars. In an effort to be more rigorous, the most recent report of the IPCC has quantified degrees of doubt, defining terms like “likely” and “very likely” in terms of percentage probability.

We've discussed the value of certainty and the generalized definitions offered by the IPCC. Would you be willing to invest your life saving is it was only 'likely' that it would be safe? When one concludes from a study that something is likely to occur in 100 years is that enough certainty to act?

Notice the shunting aside of this so called anomaly? Plus the admission that there are inherent errors in the observation and the models?

There is still some ambiguity in the tropics, where most measurements show the surface warming faster than the upper troposphere, whereas the models predict faster warming of the atmosphere. However, this is a minor discrepancy compared with cooling of the entire troposphere and could just be due to the errors of margin inherent in both the observations and the models.

I've posted evidence that the IPCC has ignored contra evidence when it suited the agenda!

I could go on Pooey but even you might get the drift by now. There is a pall of uncertainty in this whole business. A rationalization of any facts or hypotheses that cast doubt on the IPCC orthodoxy that the warmth we are experiencing is due to human activity? This has been continued even when we experienced a recent period of cooler temperatures at the same time that CO2 emissions were increasing?

By the way..

But I am not the one who's using their opinion to override those of others in this debate.

I'm not trying to override your or anybody elses opinions. I'm posting what I believe! I could care less whether you agree or disagree. Thats not the purpose of debate is it?
