 Workplace Examples 
			
On the issue of climate change, what I find most disturbing is the rate at which our planet is warming.  Just the other day, there was this portentous news story in which an official from the National Center for Atmospheric Research was quoted as saying that the ratio of record highs to record lows, which was around one-to-one until the 1970s, had risen to about two-to-one during the last decade, and continues to be on an upward trajectory.  Bottom line: an increasing frequency and duration of heat waves. 
			One of the most powerful arguments for believing in God was that made by the late William F. Buckley Jr. in one of NPR's "This I Believe" segments.  Of course, I didn't approve of the portentous language he used to make his point.  Even though it was meant for a radio listening audience, the two-minute utterance was packed with big, incomprehensible words and phrases such as "profundity," "opiate," "felicitous congeries," "jingoistic patrons," "animadversion," and the like.
