Final answer:
Climate change makes droughts more extreme through increased evaporation, changes in rainfall patterns, and decreased snowfall.
Step-by-step explanation:
One way that climate change makes droughts more extreme is through increased evaporation. As temperatures rise, more water evaporates from the land and bodies of water, leading to drier conditions and less water available for plants.
Another way is that rainfall patterns change, with more intense precipitation events expected on average. This means that rather than steady, moderate rain over time, there may be longer periods of drought followed by heavy rainfall, which can lead to greater extremes in water availability.
Additionally, as temperatures rise, snowfall decreases and more precipitation falls as rain. This means that instead of snowpack accumulating over the winter and gradually melting, there is less snow to melt, resulting in reduced water supply during the warmer months.
