Global warming also affects water availability and the water cycle. The changes in temperature, precipitation patterns and snowmelt affect water availability. The increase in temperatures will cause more water to be evaporated into the atmosphere. The water available will change from area to area. In areas where precipitation increases then water availability will probably have little or no change. But in areas where precipitation decreases or stays relatively the same, then there may be less water available. Temperatures will also increase at the poles. This temperature increase will melt glaciers and cause waters all over the world to increase. If all of the glaciers melt, the oceans level will raise and a lot of coast land will disappear and be completely submerged underwater.
