  • Will climate change affect frequency or intensity of El Niño and La Niña? There is still little consensus among scientists on this, explains the International Research Institute for Climate and Society’s Lisa Goddard.
     

  • Computer climate models help scientists such as Dave Dewitt predict the life cycles of individual El Niño or La Niña events and their effects on weather patterns throughout the world. While the accuracy of these models continues to improve, they still have limitations.
     

  • El Niño and La Niña can significantly alter seasonal climate conditions, such as temperature and rainfall patterns, in many parts of the world. Scientists Brad Lyon and Paul Block explain the potential impacts of La Niña in different parts of Africa.
