Multiple climate model studies and reanalysis data demonstrate that global warming significantly alters climate systems such as the Madden-Julian Oscillation (MJO) and El Niño-Southern Oscillation (ENSO), impacting their precipitation amplitudes, phase speeds, and wind variances.
The claim is specific, empirical, and falsifiable. Retrieved papers provide strong evidence from climate models and observational data supporting the proposition that global warming affects the behavior, intensity, and characteristics of climate systems such as the MJO and ENSO. No papers refute the claim.
