Deep ocean warming-induced El Niño changes

G. Kim, J. Oh, et al.

This groundbreaking study by Geon-Il Kim, Ji-Hoon Oh, Na-Yeon Shin, Soon-Il An, Sang-Wook Yeh, Jongsoo Shin, and Jong-Seong Kug reveals how deep ocean warming can intensify El Niño events, even in a world with reduced CO2 emissions. Get ready to uncover the dramatic consequences of anthropogenic greenhouse warming on weather variability!

Abstract
This study investigates the impact of deep ocean warming on El Niño events, even after CO2 emissions are reduced. The research shows that deep ocean warming leads to El Niño-like warming in the tropical eastern Pacific, increasing precipitation and shifting the Intertropical Convergence Zone southward. This intensifies Eastern Pacific El Niño events, potentially increasing convective extreme El Niño events by 40-80%. The findings highlight the prolonged impact of anthropogenic greenhouse warming on El Niño variability.
