El Nino activity in 2oth century and global warming
High El Nino -Southern Oscillation (ENSO) activity in the late 20th century is a footprint of global warming says a recent study.
An international team of scientists spearheaded by Jinbao Li and Shang-Ping Xie, while working at the International Pacific Research Center, University of Hawaii at Manoa, has compiled 2,222 tree-ring chronologies of the past seven centuries from both the tropics and mid-latitudes in both hemispheres. Their work is published in the June 30, 2013 online issue of Nature Climate Change.
