Ever heard of eugenics? Basically, it is selective breeding. Hitler had that in mind, but several scientists in the United States did as well. The "scientific" idea was to breed a "class" of "superior" humans. This was done in the name of science.

Ever heard of global warming? Basically, the idea, expounded by numerous scientists, is that human beings are so polluting the earth that we are destroying the ozone layer and significantly, even dangerously, contributing to global warming.

Al Gore is preaching about global warming. Heaven knows, if Al Gore says it, it must be true. But wait! Perhaps it all depends on what the meaning of "warming" is?

Remember the Ptolemaic theory? Probably not! Well, the Ptolemaic theory asserted that the universe was a closed space bounded by a spherical envelope beyond which there was nothing and that the earth was the center of everything.

Up to the time of Copernicus and beyond, most scientists accepted the Ptolemaic theory as truth.

There was one exception and that was a guy (scientist) by the name of Aristarchus. He had ideas similar to Copernicus, but most scientists favored the earth-centered theory and rejected his ideas that the sun was actually the center of things.

Claudius Ptolemy's "findings" were that the earth was a fixed, immovable mass located at the center of the universe and that all heavenly bodies revolved around it. This was accepted scientific dogma.

In 1530, Copernicus presented his work "De Revolutionibus," which proposed that the sun was the center of things and that the earth rotated on its axis once daily and around the sun.

Two other brave scientists embraced the thought of Copernicus. They were Galileo and Bruno. They suffered much persecution at the hands of the Roman Catholic Church no less!

Along with the idea that the earth was the center of everything, scientists and theologians alike came to view mankind as the center of everything. Consequently, way too much emphasis was placed on the importance of man in the scheme of things. Ironically, the same thing is now happening and once again in the name of science.

Now we have scientists and politicians asserting that, basically, mankind is again the center of things, only this time the center of things that is destroying the earth via global warming.

Mankind is creating so much greenhouse gas that the earth is warming beyond what it should, beyond what the "norm" should be.

Who are we in the scope of things, I mean after all we live at best 100 years and we're gone, to say what the "norm" is?

The earth has been around for millenniums. History has not recorded things for that long, relatively speaking. So who are we to say what the "norm" is?

There remains considerable debate about global warming and the role humans play and the role natural processes play. There are those scientists who, although you'll not hear their story reported by major news media, argue that natural processes play a more significant role in global warming than mankind could every possibly play.

Just last month scientists examining a spike in worldwide ocean temperatures 55 million years ago -- did you catch that? Fifty-five million years ago -- have linked it to volcanic eruptions that pushed Greenland and northwest Europe apart to create the Atlantic Ocean.

Let's see, how many automobiles were around then? How many factories? How many air conditioners?

So, which scientists are we to believe? Which politicians are we to believe? I think most of them are self-serving and that a genuine concern for the planet is the last thing on their minds.

Remember Chicken Little? "The sky is falling! The sky is falling!" That is what these people who are crying, "Global warming," remind me of.

Forgive me if I am scientifically skeptical about the whole thing. On second thought, don't.

Note: One example of a scientist who does NOT accept the global warming scare is Edward Wegman, Ph.D. He believes that much of the "climate science" that has been done should be taken with a grain of salt. Wegman received his Ph.D. in mathematical statistics from the University of Iowa, and, in 1978, went to the Office of Naval Research where he headed the Mathematical Sciences Division. He has served as editor or associate editor of prestigious journals and has published more than 160 papers and eight books.
