  author={Ruting Feng and Christopher J Poulsen},
Late Cenozoic marine proxy data record a long-term transition in the tropical Pacific from El Niño-like conditions with reduced zonal sea surface temperature (SST) gradient, deepened thermocline, and reduced upwelling in the eastern equatorial Pacific (EEP) to conditions similar to modern. This transition coincides with kilometer-scale uplift of the central Andes. To understand whether the rise of the Andes contributed to tropical Pacific climate evolution, we performed experiments with the… CONTINUE READING
