August 17, 2015

Research and commentary articles just published online in Nature Climate Change by NOAA/PMEL Senior Scientist Michael McPhaden and collaborators highlights the need for continued study into El Niño causes and effects. 

McPhaden’s commentary explores possible reasons why the much anticipated El Niño of 2014 failed to materialize, while an unforeseen strong El Niño is developing now. In the same issue, a review paper by McPhaden and colleagues explores the connection between global warming and El Niño/La Niña events.  Model results indicate that extreme El Niño and La Niña events will increase in number and intensity as the climate continues to warm.
