When I take a lungful of air in this moment, it has 30 percent more carbon in it than when I was born,” Oregon Sen. Jeff Merkley, the bill’s main sponsor told The Huffington Post on Wednesday

Yeah Merkley, that co2 you're breathing in comprises about .04 percent of the Earth's atmosphere. How do your lungs stand it?

When I take a lungful of air in this moment, it has 30 percent more carbon in it than when I was born,” Oregon Sen. Jeff Merkley, the bill’s main sponsor told The Huffington Post on Wednesday. “That is a change that has never happened in a single generation of humankind on this planet.”

Yeah Merkley, that co2 you're breathing in comprises about .04 percent of the Earth's atmosphere. How do your lungs stand it?

The salient point is that the content of CO₂ in your exhaled breath is 10% or so. Maybe more. That’s assuming that 20% of inhaled air is oxygen, and the lungs absorb only 50% of it, replacing that oxygen with carbon dioxide.

So we’re talking an increase in CO₂ in exhaled breath from10% to 10.04%. Al Gore once claimed that the increase in trace CO₂ intake caused brain damage. I’d say that believing that is proof of brain damage, but by no means the cause of it.
