years duration, but a new record of ENSO from a central Pacific
coral reveals much longer La Niña anomalies in the 1800s. A La
Niña event between 1855–63 coincides with prolonged drought
across the western U.S. The spatial pattern of this drought
correlates with that expected from La Niña during most of the L
