4:20 -- 68.52 ppm is 18.6% of 368,400, the total content of CO2 in the atmosphere at the time Heib wrote his blog. 18% of 3 trillion tons (total atmospheric CO2) is 558 billion tons. So if an extra 558 billion tons of CO2 has accumulated in the atmosphere from natural sources, that’s equivalent to over 50,000 Mt. St. Helen-sized eruptions (Mt St Helens emitted around 10 million tons of CO2 according to the US Geological Survey -- volcanoes.usgs.gov/vhp/gas_climate.html). An according to the CDIAC, half of the extra CO2 has been added since the mid 1980s (cdiac.ornl.gov/CO2_Emission/timeseries/global), so that means 25,000 Mt. St. Helen-sized eruptions.

"thank you for featuring my article and struggle to overcome the misinterpretation by the HockeySchtick.

1. We are looking at the accumulated CO2 concentrations (in ppm), but accumulated only over the period of our study, which is 6 months-long simulation from April 2008 to October 2008.
2. We are looking at the CO2 concentrations accumulated in a regional study, so only over the Western Europe, and thus these are not global averages, we are not simulating for example the emissions in China or USA and so on. (we do include these in a different term in our article, as they will be emissions outside our area of interest)
3. The 15 ppm mentioned in the abstract are average gradients - that means at the end of our 6 month simulation we make an average of the CO2 for every point in our area and 15 ppm is the difference between the places with lowest and highest CO2 concentration from fossil fuels.
