The concentration of carbon dioxide in the atmosphere today is about Select one: a. 170 parts
per million. b. 300 parts per million. c. 400 parts per million d. 800 parts per million. How
would a shift in land use from forest to agriculture affect atmospheric carbon dioxide? Select
one: a. It would have no effect. b. It would result in a large release of CO_2 c. It would result
in a decrease in release of CO_2 d. Neither forests nor crops contribute significantly to
atmospheric carbon dioxide Charles Keeling chose to monitor atmospheric carbon dioxide levels
at Mauna Loa Observatory because Select one: a. uptake of carbon dioxide would be greatest in
warm tropical forests b. it was located far from industrial sources of pollution that might make
interpretation of the data more difficult c. the climate in Hawaii was very different from the
climate of Big Sur (California) where he did his previous work on carbon dioxide d. the relative
contribution of fossil fue
Solution
The concentration of carbondioxide in the atmosphere today is around 400 Parts per million
(ppm). The safe level of carbondioxide in atmosphere is around 350ppm. The shift in land use
from forest to agrivulture results in large release of carbondioxide in atmosphere. Also release of
other greenhouse gasses results in global warming. Its because of the relative contribution of
fossil fuel burning to the release of atmospheric carbondioxide was debated. Its one of the major
reason for the increase in global warminh..
