The overall world fossil fuel production/consumption 1995 may be summarized as follows:
1. CO2 absorption by high productive cropland is around 800 kg CO2/km2.hour, that is around 7000 TonCO2/km2.year.
2. Assuming that the overall available world land vegetation operates at 30% of the figure stated above, the actual world CO2 average absorption capacity would amount to 2100 TonCO2/km2.year.
3. Fossil Fuel Production/Consumption (1995) are:
Natural Gas (Billion
CF): 78,276 = QuadsBTU/y:
78
Coal (Million Tons):
5,104 = QuadsBTU/y: 102
Petroleum Oil (1000 barrel/day): 69,378 = QuadsBTU/y: 160
4. The Fossil fuel related total world emissions are as follows (1995)
Total CO2 emission: 25,100 Million Tons
Total human population: 5,250 Million
Total Land Surface:
114 Million Km2
CO2
kg/capita: 4,780
CO2 Ton/km2.year: 220
5. If you compare the fossil fuel related CO2 emissions at 220
Ton/km2.y with the overall ecosystem CO2 absorption capacity of 2,100
Ton/km2.y it would seem that our non renewable sources emission amount to 10.5%
of the world vegetation absorption capacity. However it must be known that if
the ecosystem absorbs 2,100 TonCO2/Km2.y it also emits a closely
similar amount as result of vegetal decay in food chain processes.
The key
indicator of the CO2 overall balance is the concentration level of
CO2 in the atmosphere, which is known to be increasing from around
250 ppm at the beginning of the industrial revolution to actual levels around
350-400 ppm. These apparently small increments in atmospheric CO2
level explain the also apparently small world climate temperature increases, but
the effects in hurricanes, floods, and similar induced phenomena are already at
all time high records in many regions of the world (China, Central and South
America, France, Mozambique, etc).
The following tables summarize the CO2 emission of the 20 largest emitter countries accounting for 20,300 million Tons CO2 /year which represents 80.9% of the total world emission.
