Ya Dan men smoked tobacco for a long time and the tobacco companies hired their own "scientists"  to refute the facts that it is harmful.  Well over 90% of the scientists in the field of meteorology  point out that the vast majority of changes right now could be prevented by people using other energy sources, but of course the petroleum companies send 3 or 4 of their own "scientist" to Fox News to oppose one committed one belonging to the 90%.  Yes that is Fox's fair and balanced news? alright.
