European CO2 emissions by country, per capita. 10T per person seems about average. Croatia is about zero according to the chart. I guess nobody is counting and there isn't much anyway. Poverty keeps CO2 down.

Here are some total CO2 emissions going back to 1751. cdiac.esd.ornl.gov <Since 1751 more than 265 billion tons of carbon have been released to the atmosphere from the consumption of fossil fuels and cement production. Half of these emissions have occurred since the mid 1970s. The 1996 estimate for global CO2 emissions, 6518 million metric tons of carbon, is the highest fossil-fuel emission estimate ever >

So, figures seem to agree on how much CO2 we are producing.

But looky here, cdiac.esd.ornl.gov
CO2 has been increasing since 20,000 years ago with no 747s, cars or boilers. See the link for easier reading of the table - this is just an excerpt:

Meanwhile, CO2 is GOOD for plants.
co2science.org As can be seen from these data, over the period 1958-1997 the "breath" of the biosphere has been considerably enhanced. The 19.5% increase in the strength of this phenomenon is primarily a direct result of atmospheric CO2 fertilization (Pearman and Hyson, 1981; Cleveland et al., 1983; Bacastow et al., 1985; Enting, 1987; Kohlmaier et al., 1989; Keeling et al., 1996), nitrogen-induced increases in the growth rates of earth's ecosystems (Shindler and Bayley, 1993; Hudson et al., 1994; Galloway et al., 1995), and CO2-induced expansions in some of their ranges (Idso, 1995). A slight temperature increase reported in some Northern Hemisphere land areas over this time period may also be a contributing factor (Keeling et al., 1996; Myneni et al., 1997). Together, these phenomena combine to produce the results shown in the graph above, which stands as a strong testament to the reality of the ubiquitous "greening of the earth" (Idso, 1986) that is currently in progress.

Glasshouse operators in NZ [some] burn LPG or natural gas to warm the plants and give them heaps of CO2.

Volcanoes, which take subducted fish from oceanic sediment and fire them back into the air, put out a bit of CO2. What they don't fire out gets deposited in oil and gas fields [another Mq theory - on how oil is formed and deposited in sedimentary traps]. <I don't have an exact number. At Mount St Helens the maximum measured emission rate was 2.2X10^7 kg per day. The total amount of gas released during non-eruptive periods from the beginning of July to the end of October was 9.1X10^8 kg . I do not have an estimate for the volume of CO2 released during the Plinian eruptions. As a long-term average, volcanism produces about 5X10^11 kg of CO2 per year; that production, along with oceanic and terrestrial biomass cycling maintained a carbon dioxide reservoir in the atmosphere of about 2.2X10^15 kg. Current fossil fuel and land use practices now introduce about a (net) 17.6X10^12 kg of CO2 into the atmosphere and has resulted in a progressively increasing atmospheric reservoir of 2.69X10^15 kg of CO2. Hence, volcanism produces about 3% of the total CO2 with the other 97% coming from man-made sources. For more detail, see Morse and Mackenzie, 1990, Geochemistry of Sedimentary Carbonates. >

Total atmospheric CO2 according to this source = 2,700,000,000,000,000 Tonnes which is a LOT more than 27,000,000,000 Tonnes people give freedom to each year after aeons buried in the ground. Let's see, we need another 5 zeros to match the CO2 already in the air. So, we need to do what we are doing for 10,000 years to match the existing atmospheric CO2! That's a lot of hard work.

But maybe that person's total CO2 in the atomsphere is wrong?

This is where I gave up trying to prove a greenhouse effect thanks due to fossil fuel burning. The figures I found are near enough in agreement.

People are 'farting against thunder' or 'peeing in the ocean' with our fossil fuel burning. There seems a lot of it in downtown LA with gas stations on every corner. But the earth is quite big compared with downtown LA and there are few gas stations in the middle of the Pacific, though Honolulu has some.

Not everyone thinks there is a problem with human CO2 emissions: vision.net.au

PS: Any improvement on that total CO2 in the atmosphere figure would be appreciated. Still hunting!
