2. Each part per million (ppm) concentration of CO2 in the atmosphere is the equivalent to a global atmospheric mass of about 2.13 billion metric tons of CO2.In 1800, around the time of the Industrial Revolution, the atmospheric concentration of CO2 in the atmosphere was about 290 ppm. In June of this year 2020, there were around 420 ppm of CO2 in the atmosphere. How many billion metric tons of CO2 have been added to the atmosphere between 1800 and June of 2020? 3. In 1966, the atmospheric concentration of CO2 was 351 ppm. In 2014, the atmospheric concentration of CO2 was 450 ppm. Compute for the amount of increase in concentration of CO2 in ppm and in metric tons. Each ppm is equivalent to 2.13 billion metric tons of CO2.

2. Each part per million (ppm) concentration of CO2 in the atmosphere is the equivalent to a
global atmospheric mass of about 2.13 billion metric tons of CO2.In 1800, around the time of
the Industrial Revolution, the atmospheric concentration of CO2 in the atmosphere was
about 290 ppm. In June of this year 2020, there were around 420 ppm of CO2 in the
atmosphere.
How many billion metric tons of CO2 have been added to the atmosphere between
1800 and June of 2020?
3. In 1966, the atmospheric concentration of CO2 was 351 ppm. In 2014, the atmospheric
concentration of CO2 was 450 ppm. Compute for the amount of increase in concentration of
CO2 in ppm and in metric tons. Each ppm is equivalent to 2.13 billion metric tons of CO2.

Compute for the amount of increase in concentration of CO2 in ppm and in metric tons. Each ppm is equivalent to 2.13 billion metric tons of CO2.
The production of CO2 emissions worldwide is listed in the table below, indicating that from
1966 to 2006, 225 billion metric tons of CO2 were emitted. However, the atmospheric concentration
of CO2 did not increase by 225 billion metric tons. It only increased by 168.27 billion metric tons.
How do you account for the difference between CO2 emissions and the change in atmospheric
concentration of CO2? Where did the excess CO2 go? List the possible sinks that may have absorbed
some of this CO2.
