Ben Gelber: Ben Franklin on Global Warming
[Ben Gelber is a meteorologist at WCMH-TV in Columbus, Ohio, and the author of “The Pennsylvania Weather Book.”]
FEW would argue that the debate on global warming engenders a lot of emotion. What else are we to make of comments that “within the last 40 or 50 years there has been a very great observable change of climate,” that “a change in our climate ... is taking place very sensibly” and that “men are led into numberless errors by drawing general conclusions from particular facts”?
That these comments were actually tossed around back in the late 18th century by the Pennsylvania doctor Hugh Williamson, Thomas Jefferson and Noah Webster reminds us that history has a tendency to repeat itself. (One can imagine what television talk shows would have been like then. Would Jefferson have promoted “An Inconvenient Treatise” only to be acrimoniously contradicted by Webster on “Hard Quoits,” assuming either could get a word in amid the jabbering of the host?)
In the 1780s, Thomas Jefferson opined in his “Notes on Virginia” that “both heats and colds are become much more moderate within the memory even of the middle-aged,” expressing views articulated as early as 1721 by Cotton Mather: “Our cold is much moderated since the opening and clearing of our woods, and the winds do not blow roughly as in the days of our fathers, when water, cast up into the air, would commonly be turned into ice before it came to the ground.”
The weather historian James R. Fleming has noted that the vexing scientific challenge in the climate debate has always been “the response of a large, complex, potentially chaotic system to small changes in forcing factors.” Benjamin Franklin understood climatic forcing factors better than anyone, surmising in a 1763 letter to Ezra Stiles that “cleared land absorbs more heat and melts snow quicker.” Franklin, our meteorologist emeritus for his seminal work on everything from lightning to northeasters, later surmised (correctly) that a prevailing haze over parts of North America and northern Europe was associated with the eruption of the Laki volcano in Iceland in June 1783, and was possibly the source for the exceptional chill experienced in the winter of 1783-84 in the new United States...
