Explosive volcanic eruptions might be attention grabbing, but a new review of research finds that their environmental impact pales in comparison to human activities. According to the research, humans put out the same amount of carbon dioxide in three to five days that all of the volcanoes on Earth put out in one year.
"Anthropogenic carbon dioxide emissions dwarf global volcanic carbon dioxide emissions," study researcher Terrance Gerlach, of the U.S. Geological Survey, said in a statement. Carbon dioxide, or CO2, is the main greenhouse gas responsible for climate change.
Gerlach crunched the carbon dioxide numbers from earlier studies of volcanic output, finding a range of 0.13 to 0.44 billion metric tons, or gigatons, of CO2 per year. In comparison, the estimated rate of human carbon dioxide emissions for 2010 alone is 35 billion metric tons.
For instance, here are a few carbon-emitting human activities and their carbon-dioxide outputs:
Land-use changes: 3.4 gigatons per year
Light-duty vehicles (mainly cars and pickup trucks): 3.0 gigatons per year
Cement production: 1.4 gigatons per year
Present-day human carbon emissions could even exceed the CO2 output of several supervolcano eruptions, including the giant eruption that will eventually occur at Yellowstone National Park, Gerlach wrote in the American Geophysical Union's newsweekly Eos. These mega-eruptions are very rare, with the last one occurring 74,000 years ago in Indonesia.

I’m spewing right now.
We’re all gunna die ping!
That does it. I’m going to start smoking again just to piss the idiots off.
Well, it’s clear now what the final solution must be.
Now what? Do we kill ourselves to save mother Gaia?
And I just farted
Oh, this is gonna be one of THOSE threads.
Until one of those volcanoes erupts.
I guess everyone needs to stop breathing.
it’s a hoax.
atmospheric CO2 last century was much higher than today.
it went DOWN in the 1960s and 1970s.
but the warmists keep that hidden.
(they ONLY report Mauna Loa, or dubious ice cores. never direct measurements from other locations.)
simple graphs on page 5, and page 9, tell the story at a glance.
180 Years accurate CO2 - Gasanalysis of Air

If these eco-flake libtard earth worshipers would just shut their lying pieholes, we might survive.
That's a lie right there. Water vapor is the main greenhouse gas.
It would appear so.
These numbers are pure BS.
I get the impression that the author of the Eos article is scrambling to find some grant money so he can keep his job.
You know, apparently for him, ignorance is terrifying.
..and how much CO2 does all of the plant life convert into O2 and food/trees for tree huggers etc?
