You raise some interesting questions

"Global Warming" is very difficult subject to discuss.

1) We are still in the infancy of being able to predict weather

2) This issue is very political

3) Because of 1 and 2, a lot of screaming from each side is going on.

4) As Mark Twain used to say, "There are lies, damn lies, and then there is statistics!"

One of the URL's you listed was a history of the rise in ground temperature in the world in the last 100 years. This is constantly used by the "pro Global warming" people as proof of their contention. The problem with using this is that the computer models being used predict ever higher rises in temperatures in the Troposphere, and satellite measurements show that this is just not happening.

The satellite measurements show a decrease in temperature as related to height, the opposite of the computer predictions. What we have is substantial uncertainties in our understanding of how our climate system will respond to increasing concentrations of carbon dioxide and other greenhouse gases.

What we can know for sure is that the popular perception of global warming as an environmental catastrophe cannot be supported with present measurements or the current climate change theory.
