. Monthly measurements of atmospheric CO2 concentration at Mauna Loa began in March 1958. The average CO2 concentration for that month was 315.71 ppm. In 2020, the March monthly average value was 414.51 ppm. Calculate the total increase in March concentration (in ppm) from 1958-2020 (62 years). Also calculate the average increase per year.

Answer:

[tex]Increase=98.8ppm[/tex]

[tex]Average\ increase/year=1.594\frac{ppm}{year}[/tex]

Explanation:

Hello,

In this case, since the nowadays concentration of CO2 is 414.51 ppm and the concentration in 1958 was 315.71 ppm, the total increase is computed via the difference between them:

[tex]Increase=414.51ppm-315.71ppm\\\\Increase=98.8ppm[/tex]

Moreover, the average increase per year is computed considering that from 1958 to 2020, 62 years have passed, therefore, such average is:

[tex]Average\ increase/year=\frac{98.8ppm}{62 years} \\\\Average\ increase/year=1.594\frac{ppm}{year}[/tex]

Regards.

A. The total increase in March concentration (in ppm) from 1958 to 2020 is 98.8 ppm

B. The average increase per year is 1.59 ppm / year

A. How to determine the increase

  • Concentration in March 1958 = 315.71 ppm
  • Concentration in March 2020 = 414.51 ppm
  • Increase =?

Increase = (Concentration in March 2020) – (Concentration in March 1958)

Increase = 414.51 – 315.71

Increase = 98.8 ppm

B. How to determine increase per year

  • Increase = 98.8 ppm
  • Total year = 2020 – 1958 = 62
  • Increase per year =?

Increase per year = Increase / Total year

Increase per year = 98.8 / 62

Increase per year = 1.59 ppm / year
