Suggested possible question: Can one volcano emit more greenhouses gases than mankind has ever produced?
Yes, one volcano can emit more greenhouse gases than mankind has ever produced. Volcanic eruptions can release large amounts of CO2 and other greenhouse gases into the atmosphere, which can contribute to global warming. However, human activities are still the primary cause of global warming, as the emissions from volcanoes are not enough to keep up with the amount of CO2 being released by humans.
