Global climate change enhances the water cycle because the cycle of water is intensified and/or becomes more extreme.
Some correct student responses:
Megan Smith wrote, " The climate will undergo changes in response to natural variability including solar variability, and to increasing concentrations of greenhouse gases and aerosols. This will affect atmospheric water vapor concentrations, clouds, and precipitation patterns."
Courtney Kahl wrote, " Global Warming enhances the water cycle because the cycle of water is intensified or becomes more extreme. For example, more clouds will form and there will be more rain and snow."
Micah Whitsel wrote, " Potential changes in Earth's climate may include stronger hurrincanes and longer hurricane seasons due to warmer water. Many animals that thrive in colder climate may go extinct or close to it, rising sea levels, glaciers melting worldwide and LOTS of precipitation."
