Based on the given input, construct a scientific hypothesis about the cause and effect of the problem.
Decrease in precipitation in a certain region
Based on the given input, a possible scientific hypothesis could be that a decrease in precipitation in a certain region is caused by changes in regional climate patterns, possibly due to human-induced climate change impacts, such as increased greenhouse gas emissions, leading to a disruption in the water cycle, reduced moisture in the air, and ultimately resulting in reduced rainfall in the region.
Complete the following task based on the instruction and optional input provided.### Instruction:
