Which cites specific textual evidence to support the following statement from the text?
"Some human activities increase the amount of greenhouse gases, primarily CO2, and this results in additional heat being retained in the atmosphere."?
A) Most of the incoming solar radiation is short wave, high frequency wavelengths.
B) Warmer conditions will probably lead to more evaporation and precipitation overall.
C) Heat energy is absorbed by atmospheric gases, including water vapor, carbon dioxide, nitrous oxide, and methane.
D) Hansen and Lacis found that the warming effect of all those gases added together is comparable to the warming effect of carbon dioxide alone.
