AB  - While high latitude amplification is seen in modern observations, paleoclimate 
      records, and climate modeling, better constraints on the magnitude and pattern of 
      amplification would provide insights into the mechanisms that drive it, which 
      remain actively debated. Here we present multi-proxy multi-site paleotemperature 
      records over the last 10 million years from the Western Pacific Warm Pool (WPWP) 
      - the warmest endmember of the global ocean that is uniquely important in the 
      global radiative feedback change. These sea surface temperature records, based on 
      lipid biomarkers and seawater Mg/Ca-adjusted foraminiferal Mg/Ca, unequivocally 
      show warmer WPWP in the past, and a secular cooling over the last 10 million 
      years. Compiling these data with existing records reveals a persistent, nearly 
      stationary, extratropical response pattern in the Pacific in which high latitude 
      (~50 degrees N) temperatures increase by ~2.4 degrees  for each degree of WPWP warming. This 
      relative warming pattern is also evident in model outputs of millennium-long 
      climate simulations with quadrupling atmospheric CO(2), therefore providing a 
      strong constraint on the future equilibrium response of the Earth System.
