Describe possible effects of global climate change, including changes in rainfall patterns.

Global climate change can lead to significant alterations in rainfall patterns across the globe. As temperatures rise due to increased greenhouse gas concentrations, the atmosphere can hold more moisture, which may result in heavier rainfall in some regions. Conversely, other areas may experience reduced precipitation, leading to drought conditions. These changes can disrupt ecosystems, agriculture, and water supply, affecting food security and biodiversity. Understanding these potential effects is crucial for developing strategies to mitigate the impacts of climate change on both natural and human systems.
