Answer: There is increase of 4.255 in the amount of carbon in the atmosphere.

Explanation:

Since we have given that

Concentration of carbon in Earth's atmosphere in 1800 = 280 ppm

Concentration of carbon in Earth's atmosphere in 2015 = 399 ppm

We need to find the percentage increase in the amount of carbon in the atmosphere.

So, Difference = 399-280 = 119 ppm

so, percentage increase in the amount of carbon is given by


(Difference)/(Original)* 100\\\\=(119)/(280)* 100\\\\=(11900)/(280)\\\\=42.5\%

Hence, there is increase of 4.255 in the amount of carbon in the atmosphere.
