Extended Data Fig. 4: Heinrich Event Sensitivity experiment results and experiment forcings.
From: Bipolar impact and phasing of Heinrich-type climate variability
a, magnitude and duration of forcings for peaked/triangular experiments. b, magnitude and duration of forcings for sustained/square experiments. c, δ15N data (black circles), control experiment (black line), and experimental output for a range of peaked forcings with abrupt recovery (colored lines). Cooler colors indicate more extreme temperature anomalies, dashed curves indicate model output outside of the control RMSD. d, Data to model RMSD evaluation for a range of model runs. Each circle corresponds to the integrated temperature forcing for an experiment, green to blue color gradient corresponds to panel C, cool and warm colors correspond to example runs from peak and sustained forcings respectively.
