Abstract

Siberian Traps magmatism overlapped temporally with fundamental perturbations of global climate during the end-Permian mass extinction. However, the combined climate effects of carbon and sulfur emissions from large igneous province eruptions, and consequently the ecological consequences of magmatism, remain poorly understood. Here, we use a global climate model to simulate the effects of combined carbon and sulfur degassing on end-Permian climate, ocean circulation, and global hydrology with implications for the end-Permian ecological crisis and the transient sensitivity of climate to large-scale volcanic perturbations.
