By now, I'm sure you've heard about the hackers in Britain uncovering proof that advocates of manmade global warming being a scientific certainly have been caught monkeying around with their findings to justify their positions. As someone who has been following the global warming/global climate change since the early 1990s, this came as no shock to me because the debate over man's influence on global climate has never been an honest one, in my opinion.
At the heart of the Left's argument is a two-pronged statement: global warming is happening, and man is causing it. Both statements can be argued on their merits (or lack thereof), but the Left doesn't see it that way. If you deny the first half of their statement, then you are painted as irrational, non-scientific, even, as Al Gore suggested, a person akin to a Holocaust denier. Since we don't want to be seen as such, we tended to go along with the Left and accepted the entire premise as true.
Ah, but there's the rub. Contrary to popular Leftist belief, most science isn't settled. Some parts of it are, but that's only after repeated testing with the same results. Climate science is one part that is always in constant flux because there is conflicting data constantly coming in that can turn an assumed notion on its head. Scientists have a number of options when this happens: retest their hypotheses, determine whether there was an anomaly that caused the result, or ignore the result altogether. As has been evidenced with the aforementioned emails, scientists with a particular conclusion in mind chose the third option overwhelmingly.
Therein lies the problem for the Left. At some point, the truth will come out, no matter how much you try to sweep it under the rug or spin it out of existence. In this case, the truth was out there all along for people to find. Now, with the emails, the "skeptics" have the upper hand in the global climate change debate and it will be hard for the Gore side of the argument to be credible in the new environment.
So, Mr. Gore, the debate really is over...and you seem to be on the losing side of it.
