As Earth’s temperature rises, areas of the Southern Hemisphere have seen decreased levels of rain. This trend has major consequences. Water will evaporate more in the coming years. Eventually this puts more water in the air and less water on the ground. That’s bad news for crops in the area, which rely on runoffs and soil moisture to grow and yield food.

Using computer-generated climate models, researchers can see what might happen to these regions.

Matthew Herman, seen in this photo, is looking at the southern part of East Africa to figure out which regions are expected to get more future rainfall and which are going to get less. He talked about his research, and how its impact can drive decision makers to reduce water problems in these areas.
