for pathways leading to stabilization and Bern2.5CC model projected (B) global-mean surface air
temperature change, (C) annual and (D) cumulative carbon emissions, (E) global-mean surface saturation with respect to aragonite (Ω
a
), and (F) global-mean
surface total pH (pH
T
). Pathways where atmospheric CO

overshoots the stabilization concentration are shown as blue lines and pathways with a delayed
approach to stabilization as red lines; the different pathways to the same stabilization target illustrate how results depend on the specii cs of the
stabilization pathway. The label SP refers to stabilization proi le, DSP to delayed stabilization proi le, and OSP to overshoot stabilization proi le.
