He did not bother to note my very next sentence, which stated, “It is the magnitude of the effect of such pollutions on a global scale and the non-human effects that are the issues.”
I spent the rest of the letter addressing changes in the global temperature of “mother earth” for the past millennia (in previous letters to the Los Alamos Daily Post, I even presented data for the past 422,800 years when mankind was not a significant factor!) and tried to put current global observations in perspective.
I suggest that Mr. Antos do his own evaluation of how much influence volcanos have on the global temperature. Volcano effects would just be a part of the total variability in the ice core data that I referenced.
