Question

Earth has a feedback mechanism that works between the surface of the Earth and its atmosphere. Which of the statements is not correct? A) Increased atmospheric CO2 leads to an increased greenhouse effect. B) Increased glacial melting leads to decreased albedo. C) Decrease in cloud albedo leads to increased atmospheric temperature. D) Decreased atmospheric H2O leads to an increased greenhouse effect. E) Increased surface temperature leads to increased evaporation.

Answer 1

The appropriate answer is doing. decreased atmospheric water vapor leads to an increased greenhouse effect. This is not true because water vapor is a green house gas and increasing the levels of it in the atmosphere will lead to more warming. All the other answers represent appropriate feedback mechanisms associated with global warming.
