Debating the Little Ice Age

The commentaries of White and of Büntgen and Hellmann in this journal fail to prove that Europe experienced the kind of sustained falls in temperature between the fifteenth and nineteenth centuries that can justify the notion of a Little Ice Age. Neither of them adequately addresses the cogency of the anecdotal or statistical evidence as presented in Kelly and Ó Gráda's article, “The Waning of the Little Ice Age: Climate Change in Early Modern Europe,” especially with regard to the spurious peaks and troughs created by the smoothing of temperature series—the so-called Slutsky Effect.
