Three and a Half Centuries of Droughts in the American Southeast
Pederson, N., Bell, A.R., Knight, T.A., Leland, C., Malcomb, N., Anchukaitis, K.J., Tackett, K., Scheff, J., Brice, A., Catron, B., Blozan, W. and Riddle, J. 2012. A long-term perspective on a modern drought in the American Southeast. Environmental Research Letters 7: 10.1088/1748-9326/7/1/014034.
The twelve researchers say the Palmer Drought Severity Index reconstruction for their study region demonstrated that "recent droughts are not unprecedented over the last 346 years," and that "droughts of extended duration occurred more frequently between 1696 and 1820," when most of the world was shivering in the midst of the Little Ice Age. And they also state that their results "confirm the findings of the first reconstruction of drought in the southern Appalachian Mountain region, which indicates that the mid-18th and early 20th centuries were the driest eras since 1700, citing Stahle et al. (1988), Cook et al. (1998) and Seager et al. (2009). And in a warning that is just the opposite of what the world's climate alarmists contend about drought-prone regions, Pederson et al. conclude that when preparing for the future, "it may be prudent for water resources planning in the American Southeast to consider the drier centuries of climate variability that precede current experience and [the] instrumental record."
