Change in ENSO's Amplitude due to Global Warming

Future global warming obviously influences not only the global mean climate but also the climate variability. In particular, numerous studies on change in El Nino-Southern Oscillation (ENSO) associated with future global warming, which is one of the strongest interannual phenomena, have been performing. Here, using CMIP5, we analyze the mean physical patterns associated with change in ENSO amplitude, and found those patterns are different from the patterns induced by the global warming. It infers that the global warming hardly modifies the ENSO amplitude in near future.
