If water were not a polar molecule, how would the effects of climatic warming differ from those currently observed or predicted to occur in the future?

• A. If water molecules were nonpolar, then water vapor would be less effective as a greenhouse gas, and the effects of global warming would be less extreme.
• B. The effects would be worse because a loss of the polar molecular structure would lead to a greater amount of heat absorbed by water molecules and, thus, an increase in its specific heat.
• C. If water were nonpolar, the effects on global warming would be only slightly worse because there are other polar molecules that can moderate climate as water does.
• D. The effects would be drastically worse because the loss of the polar nature of water would greatly reduce its specific heat and its ability to moderate temperature.
