Researchers have made a notable discovery about El Niño weather patterns. A significant increase in intensity has been found over the past few decades.

Further details about this change are available from a recent study. The study's findings are based on a comparison of the last 40 years to the preceding 1,000 years.

A professor from the University of Michigan discussed the study's results in an interview, which can be viewed in a video. The discussion sheds light on the reasons behind the observed change in El Niño patterns.
