Transcribed Image Text:2. Carbon dioxide is an odorless, colorless gas that constitutes about 0.035% b volume of
the atmosphere. It affects the heat balance by acting as a one-way screen. It lets in the
sun's heat to warm the oceans and the land but blocks some of the infrared heat that is
radiated from the earth. This reflected heat is absorbed into the lower atmosphere,
producing a greenhouse effect which causes the earth's surface to become warmer than
it would be otherwise. Systematic measurement of CO2 began in 1957 with Charles D.
Keeling monitoring at Mauna Loa in Hawaii.
Assume that these CO2 readings (in ppm) are obtained:
319 338 337 339 328
