New Study: Thousand-Year ENSO Data from SW Tree Rings

http://news.discovery.com/earth/tree-ring-history-of-el-nino-110510.html#mkcpgn=rssnws1

Discovery News reports on a new study in Nature Climate Change extending ENSO reconstructions back to 900AD.  The authors find both regular 50-90 year cycles in El Niño amplitude across the last millennium and a trend from more La Niña conditions during the Medieval Climate Anomaly to more El Niño conditions during the Little Ice Age, largely confirming previous studies based on Pacific corals and other proxies.

Alas, Nature Climate Change is so ridiculously expensive that not even my well-endowed little college or the vast Ohio consortium of journal subscriptions it shares will buy it.  So unless a more fortunate colleague will send me a PDF of the original study, that is all I can tell you for now…
