The El Niño climate event that helped supercharge global warming to record levels in 2015 and 2016 is set for an early return, according to a forecast from the World Meteorological Organization.

El Niño events are prompted by natural fluctuation in ocean temperatures in the Pacific but have a global impact, leading to flooding, droughts and heatwaves. They also exacerbate the increased extreme weather events occurring due to the continued heating of the world as a result of human-caused climate change.

The World Meteorological Organization (WMO) said on Friday that a new El Niño was 50-60% likely before the end of 2017. “Memories are still fresh of the powerful 2015-2016 El Niño which was associated with droughts, flooding and coral bleaching in different parts of the world and which, combined with long-term climate change, led to the increase of global temperatures to new record highs in both 2015 and 2016,” said Maxx Dilley, director of WMO’s climate prediction and adaptation division.(guardian)…[+]
