Question
In 1980, atmospheric concentration of Methane (CH4) was 1566.28ppb. In 2016, the concentration of methane was 1842.4ppb.What was the percent increase of methane in the atmosphere from 1980 to 2016? Provide an answer to the nearest whole number.
Solution
To calculate the percent increase of methane in the atmosphere from 1980 to 2016, follow these steps:
-
First, find the difference in methane concentration between 2016 and 1980. Subtract the 1980 concentration from the 2016 concentration:
1842.4ppb - 1566.28ppb = 276.12ppb
-
Next, divide this difference by the original 1980 concentration to find the proportion of the increase:
276.12ppb / 1566.28ppb = 0.1762
-
Finally, multiply this proportion by 100 to convert it to a percentage:
0.1762 * 100 = 17.62%
Rounding to the nearest whole number, the percent increase of methane in the atmosphere from 1980 to 2016 was approximately 18%.
