From the last problem, what is the ratio of the ppm change in CO2 to the ppm change in CH4? Assume that the concentrations of CO2 and CH4 start at their present-day values of 400 ppm and 1.7 ppm, respectively.

An additional 10ppm of methane will change the upward IR heat flux (in tropical

atmosphere) from 289.29 W/m2

to 286.211 W/m2

, which is a reduction of 3.08

W/m2

.

An additional 10ppm of CO2 will change the upward IR heat flux from 289.29 W/m2

to 289.29 W/m2

, which is a change of 0.13 W/m2

.

Therefore, an additional 10 ppm of methane would have a much larger impact on

the outgoing infrared flux than an additional 10 ppm of CO2 at current

concentrations

The ratio of the ppm change in CO2 to the ppm change in CH4 is an additional 10ppm of methane will change the upward IR heat flux (in the tropical atmosphere) from 289.29 W/m2 to 286.211 W/m2, which is a reduction of 3.08 W/m2.

what is the ratio of the ppm change in CO2 to the ppm change in CH4?

  • An additional 10ppm of CO2 will change the upward IR heat flux from 289.29 W/m2 to 289.29 W/m2, which is a change of 0.13 W/m2.
  • Therefore, an additional 10 ppm of methane would have a much larger impact on the outgoing infrared flux than an additional 10 ppm of CO2 at current concentrations.
