Global warming will make La Niña events longer and more frequent: study

Salon  

The El Niño–Southern Oscillation is a cycle which causes periodic variations in the winds and sea surface temperatures over the tropical eastern Pacific Ocean. Through both its warm El Niño phase and its cold La Niña phase, ENSO can cause flooding, heat waves, tropical storms and other types of extreme weather. The La Niña phase specifically is associated with unusually warm winter temperatures in the South, unusually cool winter temperatures in the North and more severe hurricanes during hurricane season. These things matter now because, according to a recent study published in the scientific journal Nature, global warming is going to cause the La Niña phases to be both longer and more frequent. "This rare 'triple' La Niña sparked worldwide discussion about how global warming could change the duration of these formidable events."
