Extended Data Fig. 2 | Temporal trends of δ^13 C and δ^18 O values under
different geochronological scenarios. a, δ^13 C values assuming minimum age
for each site. b, δ^18 O values assuming minimum age for each site. c, δ^13 C values
assuming median age for each site. d, δ^18 O values assuming median age for each
site. e, δ^13 C values assuming maximum age for each site. f, δ^18 O values assuming
maximum age for each site. Each panel is shown relative to the Lisiecki Raymo
benthic oxygen-isotope stack. The 95% confidence interval for each curve was
based on 999 random replicates using resampling of residuals.
