Figure 2: Tahiti coral age and North Atlantic and Antarctic climate reconstructions.
From: Pronounced interannual variability in tropical South Pacific temperatures during Heinrich Stadial 1
(a) Greenland ice core δ18O (North Greenland Ice Core Project, NGRIP), an air temperature proxy58 (GICC05 age scale19 relative to AD 1950). Younger Dryas (YD), Bølling-Allerød (B-A), Heinrich Stadial 1 (HS1, grey bar) (as defined in refs 3,59) and late Last Glacial Maximum (LGM) are indicated. (b) North Atlantic sediment core 231Pa/230Th, an AMOC strength proxy2. (c) Antarctic ice core δ18O (EPICA Dronning Maud Land, EDML), an air temperature proxy21. Antarctic Cold Reversal (ACR) is indicated. The blue bar indicates the U-series age of the fossil Tahiti coral. For clarity, bar width represents twice the dating uncertainty. All ages are given in thousand years before present (kyr BP), where 'present' refers to AD 1950.
