                         excellent case study for global warming scenarios and a target for 
                         proxy-model comparisons. The LIG global average sea surface 
                         temperature (SST) was ~0.5 °C higher than pre-industrial (PI). 
                         Contrary to the global average, tropical SST proxy compilations 
                         and model simulations show a negative anomaly in LIG SST relative 
                         to PI. Here, we present a LIG SST record from marine sediment core 
                         GL-1180 retrieved from the western tropical South Atlantic (WTSA). 
                         The SST record is based on Mg/Ca ratios of planktonic foraminifera 
                         Globigerinoides ruber (white). Our results indicate a warmer LIG 
                         in the WTSA relative to PI and Holocene conditions. We show that a 
                         positive LIG SST anomaly in tropical regions can be explained by 
                         polar sea ice loss during the LIG, which warms the ocean surface 
                         all the way into the tropics. The disagreement between proxy 
                         results and model simulations from the fourth phase of the 
                         Paleoclimate Modelling Intercomparison Project could result from 
                         uncertainties in our proxy for SST and/or limitations of numeric 
                         models in capturing transient forcings and feedbacks in Earth's 
                         climate system and imprecise boundary conditions. Additional 
                         studies are warranted to better constrain the LIG SST evolution in 
                         tropical regions.",
