The emplacement of large igneous provinces (LIPs) is known to be a driver of climate change in Earth’s past. However, the balance of climate warming through CO₂ emission and cooling through weathering is poorly understood. To better understand the role of LIP emplacement on long-term climate change, here the authors utilize the SCION coupled climate-biogeochemical model which considers the impact of LIPs through degassing of CO₂ and enhancement of local continental weathering rates.
