   # The following graph shows the historical concentration of atmospheric carbon dioxide in the atmosphere. Carbon dioxide concentrations began increasing in the 1800s as humans started to rely on combustion for energy (carbon dioxide is a product of combustion). The increase in atmospheric carbon dioxide is linked to the increases in global temperatures known as global warming. a. What is the total increase in carbon dioxide between 1950 and 2007? b. What is the average yearly increase in carbon dioxide over this period? c. What is the total percentage increase in carbon dioxide over this period? d.

Interpretation Introduction

Interpretation:

The total increase, the average yearly increase, the total percentage increase and the average yearly percentage increase in carbon dioxide over the given period are to be calculated.

Concept Introduction:

Graphs are used to depict the change in one quantity per unit of another quantity from a set of data. These are easy to analyze and provide a clear picture of the scenario.

In graphs, one of the quantities is plotted on the y-axis and is termed as the dependent variable. The other quantity is plotted on the x-axis and is referred to as the independent variable.

It can be used to calculate the various trends occurring in that quantity over a certain period of observations. For example, decrease or increase, average decrease or increase and percentage increase or decrease etc.

### Explanation of Solution

a) The total increase in carbon dioxide between 1950 to 2007.

The total increase in carbon dioxide concentration is calculated as:

Change in CO concentration = CO2  concentration in 2007  CO2  concentration in 1950 = 382 ppm - 310 ppm = 72 ppm

Therefore, the total increase in CO2 concentration is 72 ppm.

b) The average yearly increase in carbon dioxide between 1950 to 2007.

The average yearly increase in carbon dioxide concentration is calculated as:

The total increase in CO2 concentration is 72 ppm.

Total years passed = 19502007 = 57 yearsAverage yearly increase = Total increaseTotal years=72 ppm57 years=1.3 ppm/year

Thus, the average yearly increase in carbon dioxide is 1.3 ppm/year.

c) The total percentage increase in carbon dioxide between 1950 to 2007
