Without getting into a debate on the global warming subject, I suggest that those of you not familiar with the subject, as discussed previously on this forum, and those who are new to this forum (within the last year or so) should do some searching on the topic. You will find a large number of posts (and emotion).
You will find posts that support the claims of global warming being caused by humans. You will also find posts that don't support those claims. The real problem, as I see it, is that we, as a group, can't seem to discuss the subject in any kind of civil manner. Both sides are adamant that they are right.
So, just be forewarned that if you post comments regarding the character of individuals being moronic or something similar (because they don't agree with your own position on the subject), rather than having an intelligent and civil discussion, you will most likely become the target of others who don't agree with your position. One forum member, that I am aware of, was banned from the forum because they refused to be civil with other members who disagreed with him. Please, we don't need another round those kinds of posts.
Remember, true scientific analysis of issues requires questioning and rigorous scrutiny by everyone for a long period of time and perhaps not even in our own lifetime. Without this questioning and challenging from all sides of a hypothesis, we cannot get to the true answers to the questions being asked. At various times during this analysis, there may very well be indicators that suggest a particular answer is correct but, later on, and with further questioning and new evidence, the answer may wind up being something totally different. Until the time comes that all parties are in agreement, there will be no "true" answer to the question being researched.
To add confusion to everything we have seen governments and political interests become part of the analysis, we all lose because the answers become skewed in favor of one interfering factor or another. No one wins unless the scientific community is allowed to perform their analysis without outside influence of any kind. That, in my estimation, is what true science is.
Oh, one more comment - I don't think anyone refutes the claim that there is Global Warming. The question we are looking for an answer to is "What is causing it?"
