Richard,
I think the whole thing is about money, power, and forced lifestyle modification. There are a lot of people within our society who don't like our industries and lifestyles and want to go back to simpler times. Also, there are people in government who desperately want more of other peoples' money so that they can spend more. there are peolpe in foreign nations who desperately want our wealth, and if we are dumb enough to just hand it to them, that would be just dandy. All these things are converging into a giant scheme called global warming so as to be able to accomplish all of this. Just think: the government could have vastly larger amounts of tax revenue if we would just believe in global warming! And many would be forced onto public transportation, just as many desperately want to happen - perhaps just so that they can have the road to themselves. Oh, and it might clean up some pollution too!
There really is little in the way of science in this. The data is carefully selected to give just the right results - global warming is indeed true!!! Just look at the data! Never mind that they hand picked it to make the results come out as they want it to. This is no joke. At the conference in Europe 2 months ago, the Russian scientists got a look - finally - at the data the Western Weather centers had been using from the Russian measuring stations. Guess what? The Russian scientists announced that the weather centers had hand picked the data, mostly selecting data from the cities where the temperature was rising and showed apparent global warming, and left out the data from the measuring stations out in the country within the arctic circle, data which showed NO global warming at all.
Science is supposed to be about truth, but this isn't a search for truth. Instead, it is a search for a result. They "found" it and now want you to believe it too, and if you do, then they'll get to have the results they really want - a hidden agenda that is not being discussed. I suggest that we would be quite foolish to believe in it now.
Remember that back in the 1960s and 1970s it was all about the great global freeze that was coming? Hey, whatever happened to that?
