The statement that an increase in average annual temperature will lead to a decrease in precipitation across the United States is true.

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

Answer: (B)

Temperature and precipitation don’t have a simple one-to-one relationship. Warmer air can hold more moisture, which means that when storms occur, they can bring heavier rainfall in some places. But how much it rains depends a lot on regional weather patterns, storm tracks, and seasonal factors. In the United States, warming can reduce precipitation in some regions (for example, through less snowfall and drier conditions in the Southwest) while other regions may experience little change or even more precipitation, especially in the form of heavier rainfall events. Because the response to warming varies by location and season, the idea that a rise in average annual temperature will cause a uniform decrease in precipitation across the United States isn’t correct.
