If it is not worth the effort to to do that, then the arguments cannot be considered scientifically valid.

I saw a very in depth article a while back dealing with ancient and modern tree ring analysis (and since then several TV programs). According to that article and the tree ring evidence, what we are going through right now is well within the "normal" parameters exhibited by the tree ring evidence. It was also backed up by the layers in the ancient glaciers and the conclusion of the article is that the earth is in a very "normal" state according to the ancient evidence over the geological time, in short- nothing out of the long term ordinary is happening right now, including fluctuating sea levels and CO2 levels. In fact we are in a moderate era. There is far too much knee jerk reactions going on, rather than a close and careful study of the available data that we already have on hand. The "human effect" on the earth may actually be preventing us from heading into another "cold period" that was abundant in the dark ages. Is the glass half full or half empty? Everyone had a right to their N, but let's not make a few peoples personal opinion a FACT until there is reliable proof. Look at the FREON debacles from the '70's and '80's and the impact that it had on all of us, now that has been PROVEN to be wrong so we are all stuck with far less efficient air conditioning because someone's OPINION was wrong and yet we are still living with the consequences of it. Scientist and politicians with personal agendas is the real problem. Computer modeling is only as good as the person writing the code and imputing the data, get either wrong and the output in garbage- GIGO- garbage in, garbage out. The REAL problem is that people don't get awards and grants and fame from saying that everything is NORMAL, so why do we reward people who get it wrong?
Why is it so easy for people to forget the scientific process and revert to witchcraft and sorcery?
Yep, that's my two cents worth! -Barrett www.BarrettsCustomLeather.com

This article points out a common occurrence in science. Models that are used to predict the future are notoriously fallible. They must be continually tweaked to make sense. This is the essence of science and the scientific method. Rarely do we get it right the first time.
I bring this up so there can be an intelligent conversation about the topic. There is always way too much name calling and innuendo made by commenters, as can be seen in the comments section of this article. Please, lets have a civil conversation. Without civility there can be no unemotional, fact based debate. I for one would really like to hear the rational facts from both sides of this (unfortunately) hotly debated topic.
Again, please no name calling, and only rational fact based debate.
