El Niño-like climate change in a model with increased atmospheric CO2 concentrations
TL;DR: In this paper, the authors investigated the possible causes of tropical Pacific warming, using a global coupled ocean-atmosphere general circulation model incorporating increasing concentrations of atmospheric carbon dioxide, and found that cloud cover and cloud albedo feedbacks contribute to tropical Pacific sea surface temperature increases that are greater east of 180° longitude, with attendant shifts in large-scale precipitation patterns and mid-latitude circulation anomalies in the north Pacific.
