The statement that warmer average temperatures will result in diminished US precipitation is true.

The statement that warmer average temperatures will result in diminished US precipitation is true.

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

Answer: (B)

Warmer average temperatures change how the water cycle behaves rather than simply cutting rainfall. As temperatures rise, the air can hold more water vapor (roughly 7% more per 1°C), so if moisture is available, the atmosphere can produce more or heavier precipitation. Climate warming also tends to shift where and when rain falls, leading to more intense storms in some areas and drier conditions in others. In the United States, this means precipitation trends are not simply a blanket decrease; some regions have seen wetter conditions or more extreme rainfall, while others, like the Southwest, have experienced increased drought. Because the effect of warming on precipitation is complex and regionally variable, the statement that warmer temperatures will result in diminished US precipitation is not supported.
