Research not mentioned here has shown that both El Niños and La Niñas have been acting more strangely and severely with the advent of climate change. Dr. Kevin Trenberth, senior scientist with the National Center for Atmospheric Research and a lead author with the Nobel Prize-Winning Intergovernmental Panel on Climate Change (IPCC) notes that this "opens up the possibility that the changes may be partly caused by the observed increases in greenhouse gases.” The IPCC itself has observed, "Whether global warming is affecting El Niños is now a key question."
