Considering just the effects of the carbon dioxide cycle, if the Earth were to warm up a bit, what would happen?
A) More evaporation and rainfall would reduce the atmospheric CO2 levels, and the greenhouse effect would weaken.
B) More evaporation and rainfall would increase the atmospheric CO2 levels, and the greenhouse effect would strengthen.
C) Carbonate materials would form in the oceans more rapidly, the atmospheric CO2 content would decrease, and the greenhouse effect would strengthen.
D) There would be a runaway greenhouse effect, with the Earth becoming ever hotter until the oceans evaporated (as may have happened on Venus).
E) The ice caps would melt and cool the Earth back to its normal temperature.
A) More evaporation and rainfall would reduce the atmospheric CO2 levels, and the greenhouse effect would weaken.
