I found an excellent article about Al Gore and "global warming" today. You can read it here. The following is my personal opinion on the crossing of science and politics, which is exactly what has happened on the issue of global warming.
As a blooming meteorologist, I have great interest in the SCIENCE of meteorology and climatology. Being a true scientist, it sickens me to see the ways of science cross with the ways of politics. Crossing these two fields is like trying to cross a datil pepper with a satsuma...It just doesn't blend! Science is all about trying to solve the mysteries of the universe through unbiased research and experimentation. To be a scientist, one must approach an issue completely unbiased, and answer one's questions ONLY through research. When science intertwines with politics, though, it is corrupted. If a person has a preconceived political belief and tries to "prove" it right using "science", the person is not performing true science. Their preconceived political notion clouds their judgment, effectively preventing them to see all of the evidence that both sides of the issue present. The scientific study of global warming has been infiltrated by politics, and one can see the fruit that this cross-pollination bears: It's bitter, sour, tainted. Politics MUST be separate from science, or scientific "fact" will be based only on belief, and not on the natural ways of the universe.
