I’m feeling snarky today because I’m sick of hearing know-it-alls in the media talking about human-caused global warming without lifting a finger to investigate the claims they’ve been spoonfed by the eco-lobby.
Carbon dioxide (CO2) is the most-cited culprit in our anticipated date with doom, its levels supposedly soaring because of human activity.
The mantra is oft-repeated, but less known are the real numbers:
- No. 1 greenhouse gas: water vapor.
- Portion of the atmosphere that is carbon dioxide: 0.03 percent (3/10,000ths).
- Portion of CO2 caused by human activity: 3.207 percent (or 0.0009621 percent of the total atmosphere, or less than 1/100,000th).
- Accounting for the relative effect of water vapor (a gas over which we have no control) and the relative effect of carbon dioxide, portion of total greenhouse effect attributable to CO2: 3.618 percent.
- Figuring effect of carbon dioxide multiplied by man’s contribution to CO2, the portion of the overall greenhouse effect attributable to human sources: 0.116 percent.
- Most-cited actual temperature increase over past 100 years: 0.6 degrees Celsius or about 1 degree Fahrenheit.
- Calculating for human contribution to global warming, the actual temperature increase possibly caused by humans over 100 years: 0.000696 degrees Celsius or 0.00116 degrees Fahrenheit.
- Predicted warming over next 100 years: up to 2 degrees Fahrenheit.
- Extrapolated possible human contribution to global warming over next 100 years: up to 0.0023 degrees Fahrenheit.
