Mine turns out to be pretty small …
How big is your is your carbon footprint in relation to the atmosphere? Grab a ruler, and let’s go for a walk. Make each step about one meter long, so walk as though you are a football referee. As we are walking we will both count each step and do some math. How much CO2 is in the atmosphere? Current estimates put it at 350 -380 parts per million. For ease of computation, we will round it up to the nearest 100, or 400 parts per million. Now let’s use that old fashioned math and reduce that down. 400 parts per million is the same as 40 parts per 100,000 and can be reduced further to 4 parts per 10,000. When we have finished taking 10,000 steps, stop and turn around. You have just walked 10,000 meters or 10K, which runners know is roughly 6 miles. At average walking speed this takes about 2 hours. (If you do not want to take the walk, get in your car, and drive 6 miles, just to see how far it is.) Once there, look back at where you started. Remember that all the CO2 in the atmosphere is 4 parts per 10,000. Take 4 steps back towards your starting point. Those four steps out of 6 miles represent the entire amount of CO2in the atmosphere.
Global warmists determine that the carbon dioxide caused from man as the amount we have today over what existed before the Industrial Revolution. That is debatable, with some scientists estimating that man is only responsible for 15% of that amount, but for our demonstration purposes we will concede to the alarmists that all the additional CO2 came from Man.
One step out of the 6 miles represents man’s carbon footprint from the 1880s until today. According to the National Oceanic and Atmospheric Administration (NOAA) and the Earth System Research Laboratory (ESRL) the entire CO2 increase for the earth in 2007, was 2.4 parts per million.
Once again we will assume it is all man made and, furthermore, we will round up to 2.5. The 2007 world wide carbon footprint of 2.5 parts per million translates in our walk to two and one half centimeters, or about 1 inch out of 6 miles. Some environmentalists suggest that the three hundred million people in the United States are responsible for as much as one fifth of all CO2released in a year.
Because it is easier to find Â¼ inch on our ruler, let us say that the U.S. population is responsible for one quarter of all CO2 released in the world last year. Look at the Â¼ of an inch on your ruler that represents the carbon footprint of the entire U.S… Now look back over the six miles you walked that represents the entire atmosphere.
Next, all you need to do to find your carbon footprint is divide that Â¼ inch by 300,000,000.
