Clouds have a profound effect on climate
What will be an ideal response?
This is correct. Clouds reflect incident sunlight. Water vapor itself is a
greenhouse gas. The models used to predict climate have difficulties with clouds; because of
the parametrizations, they are difficult to deal with correctly. Progress is being made in
modeling, and new generations of models will improve this situation.

Three resistors connected in parallel have the individual voltages labeled DV1, DV2, and DV3, respectively. Which of the following expresses the total voltage DVT across the three resistors when connected in this manner?
a. DVT = (1/DV1 + 1/DV2 + 1/DV3) c. DVT = (1/DV1 + 1/DV2 + 1/DV3)-1 b. DVT = DV1 + DV2 + DV3 d. DVT = DV1 = DV2 = DV3
