The carbon emissions of large igneous province magmatism are commonly associated with severe environmental crises. We developed a technique that used sedimentary mercury records to estimate these carbon fluxes through time and found that they are smaller and/or slower than assumed, which suggests that the influence of carbon-cycle feedback processes is underestimated in current models.
