The strongest El Nino in nearly 20 years, which damaged crop production in Asia and caused food shortages, has ended, the Australian Bureau of Meteorology (BOM) said on Tuesday. Climate indicators associated with El Nino, which emerged in 2015, have now returned to neutral levels, the BOM said. The end of El Nino was not unexpected with climate indicators cooling in recent months, but Australia's BOM is the first major meteorology agency to declare the end of El Nino. --Colin Packham, Reuters, 24 May 2016
