This investigation explores the impact of global warming on the El Nio-Southern Oscillation (ENSO), a pivotal climatic phenomenon with far-reaching consequences for worldwide weather patterns and ecosystems. In the context of ongoing endeavors to mitigate climate change, comprehending ENSO's response assumes a position of utmost significance. Current research suggests that the amplitudes of ENSO events may intensify in response to elevated temperatures, linked to non-linear increments in atmospheric water vapor. Furthermore, careful analysis reveals an augmented variability in sea surface temperature (SST) fluctuations during the 21st century compared to prior periods. The research also sheds light on the concurrent existence and interactions of Eastern Pacific (EP) and Central Pacific (CP) ENSO variations in the context of a warming climate. Ongoing investigations are committed to unraveling the intricacies of these phenomena and their implications for future climatic patterns. Nevertheless, uncertainties persist regarding the drivers of CP-type ENSO and heightened amplitudes, with some attributing these changes to global warming while others associate them with multidecadal rhythms.
