The Madison Green Fair committee crejeted my application to be a vendor at the April 29, 2010 Madison Green Fair, at which I planned to hand out free copies of a 2007 paper from the Oregon Institute of Science and Medicine titled e2809cEnvironmental Effects of Increased Atmospheric Carbon Dioxide.e2809d Someone speaking on behalf of the committee told me in a voicemail message that the members of the committee decided to reject my application after they read the paper. According to the voicemail message, the committeee28099s decision was based on the fact that the Green Fair is supposed to be about e2809cfune2809d and e2809cenvironmental discussion.e2809d That reasoning is strange for two reasons. First, the paper brings us the good news that increases in levels of atmospheric carbon dioxide during the 20th and early 21st centuries e2809chave produced no deleterious effects upon Earthe28099s weather and climate.e2809d Good news like that can certainly be called e2809cfun.e2809d Second, ite28099s absurd to say that a paper about the environmental effects of increased atmospheric carbon dioxide is not in keeping with the theme of e2809cenvironmental discussion.e2809d Perhaps there are certain kinds of environmental discussions that the Green Fair committee is not in favor of.
