    Kauri Tree-Ring Stable Isotopes Reveal a Centennial Climate Downturn Following the Antarctic Cold Reversal in New Zealand

  • Original language description

    The dynamics of the Late Glacial have been demonstrated by numerous records from the Northern Hemisphere and far fewer from the Southern Hemisphere (SH). SH paleoclimate records reveal a general warming trend, interrupted by a deglaciation pause Antarctic Cold Reversal (ACR, similar to 14,700-13,000 cal BP). Here, we present decadal tree-ring stable isotope chronologies (delta O-18, delta C-13) from New Zealand (NZ) subfossil kauri trees (n = 6) covering the post-ACR millennium from 13,020 to 11,850 cal BP. We find a distinct, simultaneous downturn (similar to 12,625-12,375 cal BP) in all tree-ring proxies paralleling regional tree growth declines, suggesting a widespread climate deterioration. This downturn was characterized by sustained high precipitation, low temperatures, and high relative humidity in NZ with incoming weather fronts from the South Ocean. Despite these promising results, questions remain about what drove the Kauri Downturn and how the hydroclimatic conditions were altered during this time period.
