Here's a pie chart (from a different site) with pretty much the same info, Human's contribute 0.28% of total Greenhouse gases, only a portion of that would be CO2.
(If I understand it) 
Feel free to explain it to me, what does the CO2 0.117% represent ?
What two sentences ?
The guy put the web page together. Did you expect original content ?
Feel free to discredit his reference links.  |
What's with the rolly eyes? You didn't understand the question.
Original question:

What percentage do our CO2 emmisions add to the natural release of CO2 (Russian ice pocket, volcanoes, forest fires)?

The chart you showed does not show the percentage of man-made contributions of CO2 vs natural contributions (such as volcanoes, forest fires, etc.). Photon already explained it, however. Your chart shows an adjusted figure using a mathematic formula that tries to explain how much man-made CO2 (amongst other greenhouse gases) contributes to the
overall greenhouse effect.
Your chart:
The chart is explained beneath it, including the mathematic formula he used to come to his adjusted figure, and it includes the actual requested figure. In fact, right above it there is a chart showing the close-to-actual (probably off by a bit, but I'm not sure by how much, give or take) percentage that was requested.
Basically, like photon said, humans add about 30 gigatons annually, while the carbon cycle is about 750 gigatons.
