How much does the atmosphere weigh over each square kilometer (km2)?  Recall that 106 m2  =  1 km2.

Thus according to these calculations, we are adding CO2   to the atmosphere at the rate of approximately Answer: __________ percent per year.  At this rate, can we account for the observed increase in CO2   in the atmosphere since 1950s?  CO2  content in 1959 was measured at 316 ppm (parts per million) and was 380 ppm in 2005.  What is the percentage increase in CO2   over this forty-six-year interval.
