7 billion people
Figure 100 pounds each. There’s young ones and old ones, and most of them are hungry.
700,000,000,000 pounds. 350 million tons. 18% of that is carbon (per a wiki), or 63 million tons of carbon. .038% of Earth’s atmosphere is CO2. The atmosphere weighs 5.1361×1018 kg, per Wikipedia. You’d think they’d use pounds, eh? that’s 11 times 10 to the 18th power pounds, or just, like, 5 or 6 times 10 to, say, the 15th power.
Heck, I have no idea how much a pound of carbon weighs… oh, yeah, I get it.
So there you have it, all worked out. What? Oh. The atmosphere has 1 trillion 900 billion pounds of carbon dioxide
To convert carbon to co2, multiply the carbon times 44/12.
To see if human beings have helped ward off global warming, do the calculation backward.
Or watch the Grammys.
