Is it really hard to calculate the percentage of fossil fuel CO2 emissions in the global growth of CO2 percentage in atmosphere? (It is hard to calculate its percentage in the ocean, so the numbers do not tell much actually, just a food for thought.)
The 2000 global, fossil-fuel CO2 emission estimate, 6611 million metric tons of carbon, represents a 1.8% increase from 1999.
Statistics indicate that fossil fuel use accounts for emissions to the atmosphere of ~5.5 GtC (GtC = billions of metric tons of carbon) annually.
CO2 density, according to Wikipedia, is 1.98 kg/m3 (gas at 298 K)
Again, according to Wikipedia, # As of 1994, Carbon dioxide is up 30%, from 278 ppvm to 358 ppvm; ten years later, the latest measurements from Mauna Loa show it to be at 379 ppvm [3] (http://www.usatoday.com/weather/news/2004-03-21-co2-buildup_x.htm)
100ppvm; say we take the first 5 kilometers of the atmosphere (you can take 50 km if you like), roughly giving 3.4*10^18 cubic meters; 100ppvm gives 3.4*10^15 cubic meters, which is approximately 6717 teraton. Annual fossil CO2 emission is approximately one millionth of this amount of new CO2 that was added during the past, say, 50 years.
So?
Okay, okay, the oceans. According to Wikipedia, The Earth's oceans dissolve a major amount of carbon dioxide. The resulting carbonate anions bind to cations present in sea water such as Ca2+ and Mg2+ to form deposits of limestone and dolomite. Most carbon dioxide in the atmosphere eventually undergoes this fate: if all the carbonate rocks in the earth's crust were to be converted back in to carbon dioxide, the resulting carbon dioxide would weigh 40 times as much as the rest of the atmosphere.
If you are still trying to defend the greenhouse theory, multiply that million from above by 40.
Please correct me if I'm wrong.
