How is global warming expected to affect the distribution of rainfall worldwide?

• A. It will lead to more balanced rainfall across all regions
• B. It will cause changes in the global distribution of rainfall
• C. It will enhance rainfall in already wet areas
• D. It will decrease rainfall in desert regions

Answer: (B)

The expectation that global warming will cause changes in the global distribution of rainfall reflects the complex interactions within the Earth's climate system. As temperatures rise due to increased greenhouse gas concentrations, patterns of evaporation and condensation are altered, impacting where and how precipitation occurs. Warmer air can hold more moisture, which can lead to more intense rainfall events in some areas. However, other regions may experience decreased rainfall due to shifts in atmospheric circulation patterns. For instance, areas that rely on consistent weather patterns may find these patterns disrupted, leading to droughts or increased precipitation variability. This change in rainfall distribution is not uniform; it varies across different geographical regions and seasons. Such alterations can have profound effects on ecosystems, agriculture, and water resources, thereby reinforcing the notion that global warming is a catalyst for a more intricate global rainfall pattern rather than promoting a more balanced distribution of rain.
