23. Human carbon dioxide emissions dwarf global volcanic carbon dioxide emissions.

"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.

And as I said earlier, current human CO2 emmissions dwarf the Permian Siberian Traps CO2 emmissions as well.

The Permian Extinction Event is incredibly important for us to understand right now jimlup Jan 2013 #3

TBH, probably not on a Permian level. AverageJoe90 Jan 2013 #4

It did take 80,000 years. caseymoz Jan 2013 #8

CO2 injection far higher now than Permian extinction. ErikJ Jan 2013 #16

Why didn't the Eocene Thermal Maximum lead to extinction then? caseymoz Jan 2013 #19

Still most popular theory ErikJ Jan 2013 #20

Yes, but that should have caused a runaway increase to 10 degrees. caseymoz Jan 2013 #21

Aren't they already worried about methane bubbling up in Antarctica? SunSeeker Jan 2013 #5

Not just there. There are huge methane deposits all over BlueStreak Jan 2013 #7
