A new analysis indicates that robust El Niño phenomena may hasten the rise of global sea levels as exceptionally warm waters in the Pacific reach their peak. Scholars from Sun Yat-sen University in China reported that global mean sea levels recorded an increase of 9.16 millimeters during the El Niño of 2014-2016 and 7.70 millimeters in the ongoing 2023-2024 occurrence. The research attributes most of this rise to additional water volume resulting from glacial melting and runoff, along with contributions from warmer ocean waters. Currently, Pacific temperatures are elevated by 3–6°C over the average, with a record El Niño peak anticipated this winter. The results underscore the potential hazards for at-risk coastal areas.

00:00Super El Nino events may accelerate global sea level rise.
00:03A new study has found a strong link between the two.
00:06Researchers examined major El Nino events in recent years.
00:10During the 2014-16 event, global sea levels rose 9.16 millimeters.
00:16During the 2023-24 event, they rose another 7.70 millimeters.
00:21Much of this increase came from ice melt and runoff.
00:24Warmer ocean water also contributed through changes in seawater density.
00:27Now, another exceptionally strong El Nino is developing.
00:31Pacific waters near the equator are already 3 to 6 degrees Celsius warmer than normal.
00:36Experts expect the event to reach a historic peak this winter.
00:40The findings raise concerns for vulnerable coastal communities worldwide.
00:44Some African coastlines saw nearly 30 millimeters of sea level rise during the last event.
00:49Researchers say continued monitoring will be important as this El Nino develops.
