http://www.famousscientists.org/bill-nye/ he studied under Carl Sagan; he has a bachelors of science degree in mechanical engineering he worked for [b][i][u]BOEING[/u][/i][/b] as a mechanical engineer prior to his PBS kids educational show. the climate system of the planet is a biological system of mechanical action; the currents and temperature differentials and chemical composition of those currents and cyclic systems are [b][i][u]exactly[/u][/i][/b] what comprise, make up and control the planet's climate. being a person with both a degree and experience in mechanical engineering Bill Nye is actually [b][i][u]MORE[/u][/i][/b] reliable in aptitude at evaluating meteorology (study of weather) than most actual meteorologists as Bill Nye has experience and training on applications of chemical compositions of materials and their effects on a mechanical system. for a time he also served as a professor at Cornell University no offense but F this topic; dang vicious political trolls [b][i][u]PSA/FYI; the Heritage Foundation and the Tea Party are funded by the Koch Brothers; those organizations publish a ton of slanted propaganda lies BTW[/u][/i][/b]
