All volcanoes’ greenhouse gas emissions per year is less than 1/100th of Humanity’s!
(Massive Eruption of Mount Etna 2021)
According to both the U.S. Geological Survey (USGS) and a recently released report on Carbon Emission (Deep Carbon Observatory program, the National Academy of Sciences Washington, D.C., US),
the world’s volcanoes, both on land and undersea, generate 280 to 360 million tons of carbon dioxide (CO2) annually,
while our automotive and industrial activities cause annual carbon emissions up to 100 times greater than all volcanic emissions.
