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.

Does that include plowing the ground to grow food? Probably. Anything to inflate their statistics.
Nitrogen (N2)
78.08%
Oxygen (O2)
20.95%
Argon (Ar)
0.93%
Neon, Helium, Krypton
0.0001%
Carbon dioxide (CO2) 0.038%
Water vapor (H20) 0-4%
Methane (CH4) trace
Sulfur dioxide (SO2) trace
Ozone (O3) trace
Nitrogen oxides (NO, NO2, N2O) trace
Liberals spew mega-tons of putrid bile and pure garbage daily.
Naw, only liberals spew that much pollution into the air. It’s time to ban liberals.
Ping.
You’re so wrong. It’s 90% of all statistics are made up out of whole cloth.
writing crappy article for Yahoo: 18 Billion metric tons of carbon
Would they rather it be the other way around?
Crazy Lefty’s obsession is to get your goat. He-she will do it with increasingly hysterical lies. He-she wants the shouting, agony, and generally, attention, in reply.
Opps! there some Methane.
Excuse me.
Oh, Oh they gotta go. Humans have got to go! They’re killing us!
It’s very clear now, there is no other solution; the earth must be cleared of all humans and all human endeavors should be refocused to achieving that goal, so we can leave the earth exactly as it was before we arrived!!!!! /sarc
In that case, it’s fortunate that CO2 isn’t harmful.
Of course, it goes without saying that the Gaia goofballs hate humans.

Funny go to solarweather.com and the sun is really spotted.
I don’t think they will be able to carry this much farther.
Some people are just born stupid and ignorant.
Geez, and Just yesterday I was reading that the friggin sea nettles were the greatest polluters/.
I wish thes “Scientists” could make up their minds.
