Question

Carbon dioxide levels in the beginning of the Industrial Revolution was about 280 ppm (parts per million). If carbon dioxide levels have increased 38%, how much carbon dioxide is now in the atmosphere?
10640


737 ppm


8960 ppm


386 ppm

Answer 1

Answer:

The level of carbon dioxide in the now is $386 \ ppm$

Explanation:

It is given that carbon dioxide at the beginning of industrial revolution is $280 \ ppm$. It then increased by 38%.

$\frac {final level-initial level}{initial level} \times 100=38$

$final \ level = 38/100 \ initial\ level+initial\ level$

$=\frac{38}{100} \times 280 + 280=386 ppm$

Thus the current amount of carbon dioxide is $386.4 \ ppm.$

Increasing carbon dioxide level is a growing concern. It is a result of industrialization and urbanization which has serious consequences. Increased level of carbon dioxide accelerates global warming and it increases the temperature of earth.
