Intensification of Southern Hemisphere westerly winds 2000–1000 years ago: evidence from the subantarctic Campbell and Auckland Islands (52–50°S)

Abstract: The Southern Ocean plays a significant role in driving global climate–ocean–carbon dynamics. Unfortunately, a relative dearth of datasets across the region limits our ability to understand past and future mechanisms of change. Here we report a new dataset from the south‐west Pacific: radiocarbon‐dated subfossil tree stumps (Dracophyllum) eroding out from peat exposures on Campbell and Auckland Islands (52–50°S). Dracophyllum are the southernmost growing trees in the south‐west Pacific and their growth on expos… Show more

“…Our results imply that the central Southern Hemisphere westerlies were particularly strong between 2000 and 1000 cal. BP and/or lay close to the latitude of the Falkland Islands -at least within the South American sector and possibly hemispheric-wide (Turney et al, 2016) (Fig. 7).…”

“…However, no substantive change in Northern Hemisphere 14 C is recorded across 1860 C.E., with relatively young ages across this period (Figure ). Importantly, paleoreconstructions indicate that alongside a warming climate post‐LIA [ PAGES 2 k Consortium , ], there were highly variable changes in westerly airflow across the midlatitudes of the Southern Hemisphere [ Lamy et al ., ; McGlone et al ., ; Turney et al ., , ], suggesting that the Southern Ocean sea‐air flux of 14 CO 2 may play a role.…”
