New Scientific Publication: Defining El Niño indices in a warming climate

The Climate Centre co-authored an article that suggests a new way of defining El Nino. This major climate oscillation affects rainfall and temperature around the world, from drought in the Horn of Africa to floods in Peru. An El Nino event has historically been declared when a specific section of the Pacific Ocean is warmer than usual. With climate change, however, ocean temperatures are rising, and our definitions of El Nino and La Nina events have been affected by this and have been less associated with worldwide impacts.
