Diversity of El Niño Variability Makes Prediction Challenging
The atmospheric response to El Niño, both in the Pacific region and around the world, changes with each event and is uncertain in future under the influence greenhouse gas forcing.
Learning from an Extreme El Niño
A recent paper in Reviews of Geophysics describes new scientific insights on the El Niño-Southern Oscillation from analysis of the 2015-2016 extreme El Niño.
Is Global Warming Suppressing Canonical El Niño?
A study explores the relationship between diverse El Niño events and the background state of the tropical Pacific.
Improving Our Understanding of El Niño in a Warm Climate
A new study seeks to bring together the strongest features of proxy data and climate models to reduce uncertainties in reconstructions of past El Niño behavior.
How "Godzilla" El Niño Affected Tropical Fish in Low-Oxygen Zone
A warm period unexpectedly boosted some species of fish larvae off the coast of Mexico.
In the Eastern Pacific Ocean, the "Blob" Overshadows El Niño
Underwater gliders and ocean modeling reveal unexpectedly weak El Niño effects on a major West Coast current.
El Niño Will Increase Atmospheric Carbon to Historic Levels
Tropical fires and drought-stricken ecosystems that normally serve as sinks will release carbon, contributing to high atmospheric concentrations through 2016 and beyond.
Could We Have Predicted What El Niño Would Bring?
Researchers take a retrospective look to see if precipitation and flooding due to El Niño could have been predicted a priori.
Distant Rains Contributed to La Niña Ocean Warming Event
Unusually low salinity intensified a warm-water current off the coast of Western Australia in 2010–2011.
