The 2023-24 El Nino has peaked as one of the five strongest on record.
It will continue to impact global climate in the coming months despite a weakening trend.
The prevailing El Nino conditions fuelled record temperatures and extreme events the world over, with 2023 being the warmest on record.
It has displayed a peak value of about 2.0 degrees Celsius above the 1991 to 2020 average sea-surface temperature for the eastern and central tropical Pacific Ocean.
This made it one of the five strongest El Nino events ever, though it was weaker than the 1997-98 and 2015-2016 events.
The global mean temperature has breached the 1.5-degree Celsius threshold for an entire year for the first time in January.
Every month since June 2023 has set a new monthly temperature record -- and 2023 was, by far, the warmest year on record.
El Nino is a periodic warming of the ocean surface in the central and eastern tropical Pacific Ocean.
It occurs every two to seven years on an average, and typically lasts nine to 12 months.
