What effect does a decrease in precipitation have as a result of climate change?

• A. Increased flood risk
• B. Enhanced groundwater availability
• C. Increased drought likelihood
• D. Decreased air pollution

Answer: (C)

A decrease in precipitation as a result of climate change leads to an increased likelihood of drought conditions. Drought occurs when there is insufficient moisture to meet the usual demands of the environment. This can affect water supply for agriculture, drinking, and natural ecosystems, making it a critical concern in areas dependent on regular rainfall. Climate change can alter precipitation patterns, often leading to longer dry periods and reduced rainfall within certain regions, which exacerbates the onset and severity of droughts. These conditions can result in higher temperatures and reduced water availability, further stressing both natural vegetation and human activities reliant on water. The other options suggest effects that typically occur under different circumstances—such as flood risks or enhanced groundwater availability—which generally relate to increased precipitation or rainfall, rather than a decrease.
