Global Warming Tolls the Death Knell for Tuvalu

‘I want to leave this country. When the spring tide comes and the gale winds blow, it will be over for us. We realize that disaster is all too certain to strike us.’

How Much CO2 Are You Producing?

Posted by edro on August 8, 2008

Original Entry: World CO2 Emissions

World Anthropogenic CO2 Emissions from Fossil Fuel Consumption (including Flaring) Cement Production and Tropical Deforestation

CO2 This Year ( From 1-1-2008 to 8-8-2008 )
23,803.61 MMT CO2

CO2 Total 2007
38,058.66 MMT CO2

Anthropogenic CO2 Total (1750 – Today)
1,358,931.31 MMT CO2

Total atmospheric CO2

3,008,879.36 MMT [3,008.88GT]

How much CO2 are YOU producing?

Each dollar you earn or spend produces 584 g of CO2. [See Carbon Footprint of Your Dollar]

How much CO2 was there before?

Measurements of CO2 levels in Ice cores collected in Antarctica and Greenland indicate that the preindustrial carbon dioxide level was 278 ppm. Between 1000 and 1800 A.D. that level varied by no more than 7 ppm.

What about human activities?

The CO2 levels have now reached 386 ppm, which means human activities have increased the concentration of atmospheric CO2 by 109 ppm or 39 percent.

Notes:
MMT: Million Metric Tons
GT: Gigatons (billion tons)
Sources: CASF/MSRB; CDIAC; Netherlands Environmental Assessment Agency; Earth Systems Research Laboratory; Mauna Loa CO2 monthly mean data.

The following data were used to calculate the total mass of atmospheric CO2 :
1. Mass of dry air: 5.1352 × 1018 kg
2. The mean molar mass of air: 28.9625 g/mol.
3. Molar mass of CO2: 44.0095 g/mol.
4. Mauna Loa CO2 monthly mean data: 385.60ppmv

[Note: On various websites reporting the carbon dioxide emissions since 1750 the cumulative amount varies from about 1.3 – 1.8 trillion tons. On one website the amount is published once as 1.36 trillion tons and again as 1.71 trillion tons of CO2 on separate pages. Understandably, no sources are quoted. ]
