A student researches changes in the concentrations of greenhouse gases in the atmosphere over the past 2,000 years.

*Forests help absorb CO2

*Burning and deforestation add CO2 to the atmosphere.

*Agriculture and fossil fuel use result in CH4 production.

*The average lifetime of N2) in the atmosphere is 121 years and of CH4 is 12.4 years.

*The industrial era began around the year 1750.

Which argument about the primary cause for the atmospheric changes is best supported by the evidence?

The changes are caused by deforestation because it removes trees that absorb CO2.

b)

the changes are mostly caused by Earth's current position in the solar system which is different than it was 2,000 years ago.

c)

The changes are caused by the long periods of time needed for N2O and CH4 to break down in the atmosphere.

d)

The changes are mostly caused by industrial activities since those activities began at a similar time as the major changes in greenhouse gas concentrations.
