Water & Global Change

The most important impacts of Climate Change will be on the Earth’s water cycle.

Understanding the water cycle and how it will be modified by climate change is a real challenge. The water cycle describes the constant movement of water from ocean to atmosphere to the land surface and back to the ocean. On a global scale the total amount of water does not change but where it is distributed does.

This website can be your guide to understanding the water cycle and how climate change affects it. Using our maps you will be able to visualise changing rainfall patterns, evaporation and soil moisture.
