Here we exploit a bidecadally resolved 14C data set obtained from New Zealand kauri (Agathis australis) to undertake high-precision alignment of key climate data sets spanning iceberg-rafted debris event Heinrich 3 and Greenland Interstadial (GI) 5.1 in the North Atlantic (~30,400 to 28,400 years ago). We observe no divergence between the kauri and Atlantic marine sediment 14C data sets, implying limited changes in deep water formation. However, a Southern Ocean (Atlantic-sector) iceberg rafted debris event appears to have occurred synchronously with GI-5.1 warming and decreased precipitation over the western equatorial Pacific and Atlantic. An ensemble of transient meltwater simulations shows that Antarctic-sourced salinity anomalies can generate climate changes that are propagated globally via an atmospheric Rossby wave train. #------------------ # Funding_Agency # Funding_Agency_Name: Australian Research Council # Grant: FL100100195, DP170104665, SR140300001 #------------------ # Funding_Agency # Funding_Agency_Name: Natural Environment Research Council # Grant: NE/H009922/1, NE/H007865/1 #------------------ # Site_Information # Site_Name: Lynch's Crater # Location: Australia/New Zealand>Australia # Country: Australia # Northernmost_Latitude: -17.37 # Southernmost_Latitude: -17.37 # Easternmost_Longitude: 145.69 # Westernmost_Longitude: 145.69 # Elevation: 760 m #------------------ # Data_Collection # Collection_Name: LC98carbon # Earliest_Year: 33944 # Most_Recent_Year: 27678 # Time_Unit: Cal.
