Paleoclimate proxy records suggest reduced tropical Pacific zonal asymmetry under sustained global warming by Eui-Seok Chung, Seong-Joong Kim, Keith B. Rodgers, Sang-Yoon Jun, Joo-Hong Kim, Sun-Seon Lee, Kyung-Sook Yun

“…Paleoclimate proxy records indicate an overall increase of the zonal gradient over time, which has been accompanied by global-mean cooling associated with decreasing carbon dioxide concentrations. Model simulations are found to broadly reproduce the distinct contrast between warmer high carbon dioxide climates and the opposite climates, albeit with large inter-model discrepancy. …”
