Volcanic eruptions are often preceded by precursory increases in the volcanic carbon dioxide (CO2) flux. Unfortunately, the traditional techniques used to measure volcanic CO2 require near-vent, in situ plume measurements that are potentially hazardous f...

The end of the Permian period is marked by global warming and the biggest known mass extinction
on Earth. The crisis is commonly attributed to the formation of large igneous provinces because continental volcanic
emissions have the potential to control a...
