What is the impact of climate change on water resources?

The impact of climate change on water resources is primarily characterized by altered precipitation patterns. As global temperatures rise, the water cycle changes, leading to shifts in where and how much rain falls. Some regions may experience increased rainfall and flooding, while others may suffer from decreased rainfall and prolonged droughts. These changes can affect water supply reliability, impacting agriculture, ecosystems, and human consumption.

The other options do not accurately reflect the complex relationship between climate change and water resources. Consistent rainfall is not a typical outcome, as climate change often leads to variability. Water conservation remains essential despite shifts in water availability, given that changing climates may create situations of both excess and scarcity. Finally, climate change does not guarantee an increase in water availability; rather, it introduces uncertainty and potential reductions in reliable access to water resources.
