S1: before the Wrangellia Large Igneous Province (LIP) eruption, carbon- isotope values were stable; S2: the Wrangellia LIP began releasing isotopically light carbon, pre-onset excursion (POE) appeared, and temperatures started to rise11; S3: the Wrangellia LIP continued or weakened, carbon-isotope values were relatively stable, and temperatures probably continued to rise; S4: temperatures reached their peak and carbon isotopes showed an abrupt negative shift; S5: the burial of isotopically light carbon exceeded its emission, and carbon-isotope values recovered.
