No: it is not much (a lot)
310 ppm = 310 mg per kg = 0.310 g/kg = 0.0310 g/100g = 0.0310% CO2
In 2000 carbon dioxide emissions were 368 ppm (parts per million). This year (2013) they reached 400 ppm. At the beginning of the Industrial Revolution they had been 280 ppm for thousands of years.
There is 21% oxygen in the atmosphere and 300 ppm (0.03%) carbon dioxide. This translated to 700 times more oxygen than carbon dioxide.
Carbon dioxide levels in the atmosphere between 1000 and 1800 were steady around 280 ppm (parts per million). Levels now (2013) are approaching 400 ppm.

100 ppm
391.03 ppm in November 2012.
Carbon dioxide levels in the atmosphere in 1993 were around 360 ppm (parts per million). Levels now (2013) are approaching 400 ppm.
Carbon dioxide levels in the atmosphere in 1996 were around 358 ppm (parts per million). Levels now (2013) are approaching 400 ppm.
Carbon dioxide levels in the atmosphere in 2000 were around 370 ppm (parts per million). They are now (2013) approaching 400 ppm.
Carbon dioxide levels in the atmosphere in 1910 were around 290 ppm (parts per million). They are now approaching 400 ppm.
Carbon dioxide levels are not decreasing in the atmosphere, in fact, they are increasing. In 1960 levels were 316 ppm. In 1970 levels were 325 ppm. In 1980 levels were 338 ppm. In 1990 levels were 353 ppm. In 2000 levels were 369 ppm. In 2010 levels were 388 ppm. Jan of 2012 levels were 393.09 ppm. As of today we are at 393.68 ppm at Manua Loa.
380-400 ppm
No. Nitrogen is about 78% of the atmosphere or 780,000 ppm. 380 ppm is about the concentration of carbon dioxide
In 2000 carbon dioxide emissions were 368 ppm (parts per million). This year (2013) they reached 400 ppm. At the beginning of the Industrial Revolution they had been 280 ppm for thousands of years.
Carbon dioxide levels in the atmosphere in June 1994 were around 350 ppm (parts per million). Levels now (2013) are approaching 400 ppm.
Carbon dioxide levels in the atmosphere in 1960 were around 315 ppm (parts per million). Levels now (2013) are approaching 400 ppm.
In the mid-1700s the levels of carbon dioxide in the atmosphere were about 280 ppm (parts per million).In 2004 the levels of carbon dioxide in the atmosphere were about 375 ppm.In 2012 the levels of carbon dioxide in the atmosphere were about 393 ppm.
