Nobody has to believe what I or the writer of this article say. You can google all the information from government agency files just like i did. What you have to keep in mind is the blah in the nice pages you find at NOAA and NASA to name two sources is not the actual data, it is the opinion of the people who run the place. If you look at the actual studies most of the time the front page opinion in the nice grafts and words is not actually supported by the study. I used to be an auditor for 27 years, we never believed what anybody said, we dug down until we found the truth which might be what they said but what I found was most of the time it was not. Collected a few hundred million and sent some crooks to jail for doing that so just call me skeptical when it comes to claims.
