image: The Line Islands are ideal places for obtaining records of past ENSO activity because they are close enough to the source region for ENSO to be affected by its temperature and precipitation variations, but not so close that the islands’ corals are bleached by large temperature increases during strong El Niño warm events. This image relates to a paper that appeared in Jan. 4, 2013, issue of Science, published by AAAS. The paper, by Kim Cobb at Georgia Institute of Technology in Atlanta, Ga., and colleagues was titled, “Highly Variable El Niño–Southern Oscillation Throughout the Holocene.” view more
