Carbon footprint. Carbon credits. Funny looking light bulbs. They say that human-produced CO2 in the atmosphere is causing accelerated global warming and/or climate change. Yea, right! If you buy into this ludicrous notion, it may be time to give the claim a reality check.
If the Earth's atmosphere were to be represented on a 100 yard (91.44 meters) football field (an American football field), the make-up would look like something this:
From the goal line, go down 78 yards to the 22 yard line on the other end, and you have nitrogen.
Go 21 yards further, to the 1 yard line, and you have oxygen (99 yards total so far).
From the 1 yard line to the 3 inch line, you have argon.
From the 3 inch line to the 1 inch line, you have other gasses.
The last 1" would be representative of the CO2 in the atmosphere.
Let's switch our units from inch to millimeters. One inch equals 25.4mm
95 percent of that last inch (25.4mm) is CO2 that comes from water vapor - that is, evaporation from oceans, lakes, rain water, and so on.
That leaves 1.27mm left on the field.
Out of that remainder, 0.678mm is CO2 from natural sources - volcanoes and other stuff from the earth.
That leaves 0.591mm - just over one-half of one millimeter - which is CO2 produced by human (and other creature) activity.
Out of that 0.591mm, about half is from CO2 exhaled (and/or exhausted) from living creatures, including us dastardly, planet-destroying, humans.
Which leaves 0.295mm - about one-fourth of one millimeter - of CO2 emissions from automobiles, power plants, SUVs, and anyone driving a Toyota Prius. (I wonder what the overall percentage difference would be between a Ford F250 pick-up and a Toyota Prius? It probably couldn't even be measured as a percentage of the whole.)
And they claim we're destroying the planet. Yea, right. The more you look into the claim, the sillier it gets. And the more you consider the real motives ........ the more it makes you wonder.
