A new post on The Hockey Schtick reviews a new paper “that finds only about 3.75% [15 ppm] of the CO2 in the lower atmosphere is man-made from the burning of fossil fuels, and thus, the vast remainder of the 400 ppm atmospheric CO2 is from land-use changes and natural sources such as ocean outgassing and plant respiration.”
This new work supports an old table from the Energy Information Administration which shows the same thing: only about 3% of atmospheric carbon dioxide is attributable to human sources. The numbers are from IPCC data.
Look at the table and do the arithmetic: 23,100/793,100 = 0.029.
URL for table: http://www.eia.doe.gov/oiaf/1605/archive/gg04rpt/pdf/tbl3.pdf
If one wanted to make fun of the alleged consensus of “climate scientists”, one could say that 97% of carbon dioxide molecules agree that global warming results from natural causes.

UPDATE:
Thanks to everyone who pointed out the difference in the chart and the issues.
I was offered this post by the author in WUWT Tips and Notes, here: http://wattsupwiththat.com/tips-and-notes/#comment-1696307 and reproduced below.
The chart refers to the annual increase in CO2, not the total amount. So it is misleading.
Since the original author had worked for the Tucson Citizen I made the mistake of assuming it was properly vetted.
The fault is mine for not checking further. But as “pokerguy” notes, it won’t disappear. Mistakes are just as valuable for learning. – Anthony Watts

Mr. Watts,
John Droz suggested I contact you.
On my blog, I commented on the reasearch by Denica Bozhinova on CO2 content due to fossil fuel burining. She apparently scared The Hockey Schtick into taking down his post on the matter. However, there is an older table from EIA which I reproduce on my post.
Denica Bozhinova has commented extensively, and frankly, I can’t understand her position since she seems to contradict what she wrote in the abstract to “Simulating the integrated summertime Ä14CO2 signature from anthropogenic emissions over Western Europe”
See my post here (you may reprint it if you wish):
