What was the atmospheric concentration of CO2 when Obama took office?
The atmospheric concentration of CO2 recently hit 400 parts per billion (I guess by volume).
And I saw a big stupid SUV today with a stupid bumper sticker that said:
"The price of gasoline when Obama took office was $1.81."
On the plus side, the bumper sticker nice logo for Obama, the campaign logo. So I did find something nice to say about it. It was a very clean & shiny SUV, too.
If the Earth Science folks don't know then I can ask it in Politics :)
Note: I am assuming the right answer is somewhere between 220 ppb and 400 ppb, but I would like a more specific figure, so that I can create an argumentative bumper sticker
HINT:
Here is a nice graph of the Keeling Curve

It appears to be about 388 ppb in 2008.

at the start of the industrial revolution , it was 220 ppm . last week NOAA announced it had hit 400 ppm . that is the point of no return , the earth WILL go into a permanent , irreversible , greenhouse effect . by 2018 , after 5 years of worldwide crop failures , food will be made from people ( shades of soylent green ) , by 2023 the seas will have boiled off into space and humanity turns to dust .
see you on the other side .
