Concept:Global warming raises Earth’s average temperature and triggers environmental changes that directly affect people and ecosystems.
Explanation:Global warming leads to the melting of polar ice caps and glaciers.
This melting adds extra water to the oceans, causing sea levels to rise.
Higher sea levels increase the risk of coastal erosion and flooding.
Warmer ocean temperatures also intensify storms, bringing heavy rainfall and flash floods.
Low-lying coastal regions and islands are especially vulnerable to repeated flooding.
Among the listed options, flooding is a direct and widely observed consequence of global warming.
Air pollution and water pollution are causes or side effects, not primary consequences.
High humidity is a local weather condition, not a broad global warming outcome.
Answer:C. Flooding
