Despite issuing several new climate regulations to reduce atmospheric CO2 concentrations, EPA Administrator Gina McCarthy doesn't know what percentage of the atmosphere is made up of CO2.
REP DANA ROHRABACHER: "Let me ask you, what percentage of the atmosphere is CO2?"
ADMINISTRATOR GINA MCCARTHY: "What percentage of the atmosphere is CO2? I don't have that calculation for you, sir."
REP ROHRABACHER: "Maybe you could tell us what your personal guess is on what percentage is CO2."
ADMINISTRATOR MCCARTHY: "I don't make those guesses, sir."
REP ROHRABACHER: "You're the head of the EPA and you don't know? You've based, you have all of these laws based on... Oh, you're going to get your staffer to tell you now. But, you're the head of the EPA and you did not know what the percentage, and now you are basing policies that impact dramatically on the American people, and you didn't even know what the content of CO2 in the atmosphere was which was the justification for the very policies you're talking about. Well, thank you.
ADMINISTRATOR MCCARTHY: "If you're asking me how much CO2 is is in the atmosphere, not a percentage but how much, we have just reached levels of 400 parts per million."
REP ROHRABACHER: "I was asking, I think I was very clear what I was asking and it was clear you didn't know."
