According to climate models, rising average annual temperature will cause decreased precipitation across the United States.

• A. True
• B. False
• C. Not enough information
• D. It depends on context

Answer: (B)

Rising temperatures don’t imply a uniform drop in precipitation everywhere. As the climate warms, the atmosphere can hold more moisture, and circulation patterns shift, so rainfall is redistributed and can become more extreme. In the United States, models project regional differences: some areas may become drier while others may see wetter conditions, and the timing and intensity of precipitation can change with seasons. Because of this regional variability, there isn’t a single nationwide trend of decreasing precipitation. That’s why the statement is not supported by climate models.
