Fig. 2: Weathering rates in pCO2 = 35 ppmv and carbon balance state with uniform weatherability assumptions in 580–560 Ma.

a–e Weathering rate when pCO2 = 35 ppmv; (f–h) Weathering rate when pCO2 has increased to the level (label on the top) in which weathering rate would be balanced by VCO2; (i) changes of continental areas in the tropics (CAT, blue line with left axis), global sum weathering rate in (a–e) (solid orange line), (f–h) (dashed orange line), and VCO2 (global sum weathering rate in 580 Ma when pCO2 = 35 ppmv) with 10% variation (shaded orange zone). The gray contour lines represent the edges of sea ice with gridbox fraction of 50% in each panel. The global sum weathering rates have been shown at the top-right in (a–h) with the unit: mol C/yr. The names of continents have been labeled in panel (a–e).
