Twenty million tons. That's about what humans emitted every year in the 1990s.



Go to my first post of this string ..... the Volcano released

"Nearly 20 million tons of sulfur dioxide were injected into the stratosphere in Pinatubo's 1991"

So, one volcano, at one moment in time, released the same amount of CO2 as the worlds population in one year (by your post)

How many major Eruptions are there? While back, European air space was shut down due to Volcanic activity .. then Mt St Helens ... many others

It is estimated there are 1500 volcanoes on land and an unknown number under the oceans.

50-70 on land volcanoes are considered active (erupting) each year. At any given time, there is an average of about 20 volcanoes that are erupting.

So, just in comparison to Volcanos, man is but a spit in the wind.

Then there are the many other known sources spewing CO2 around the world.
