A strong El Niño phenomenon has intensified into a "super El Niño", entering uncharted territory. This natural climate cycle has been rapidly intensifying since it was first declared in June. It is now stronger than it has ever been at this time of year and is expected to continue gaining strength.

The key indicator of its force has surpassed the threshold for a "very strong" or "super" intensity, and will keep increasing. El Niño is characterized by above-average water temperatures along the equator in the Pacific Ocean, which trigger atmospheric changes.

Further details on this phenomenon are available from meteorologist Mary Gilbert, CNN.
