Concept:Long-term changes in a region's temperature and rainfall are often linked to changes in atmospheric wind systems.
Explanation:Winds carry both heat and moisture from one region to another.
A shift in the prevailing wind pattern can change the type of air that reaches a region.
If the new winds bring cooler and drier air, the region will experience lower temperature and less rainfall.
This kind of change can last for decades, causing a clear shift in the local climate.
Rising global temperatures usually warm an area, while deforestation reduces rainfall but tends to increase temperature. Neither explains a decrease in both temperature and rainfall.
Answer:D. Shift in wind pattern
