Final answer:
The overall pattern of water stress projections for the U.S. is expected to be variable due to varying precipitation and storm changes by season and region, with some areas experiencing less precipitation while others experience more.Corrrect option is d.
Step-by-step explanation:
The overall pattern of water stress projections for the U.S. is likely to be d) Variable. Projections show that future precipitation and storm changes will vary by season and region. Some regions may have less precipitation, some may have more precipitation, and some may have little or no change.
However, climate models also indicate that the amount of rain falling in heavy precipitation events is likely to increase in most regions, while storm tracks are projected to shift towards the poles. Therefore, the overall pattern of water stress in the U.S. is expected to be variable.
