Global Precipitation Trend<br />

• Precipitation is change in a more complicated way.<br />

Precipitation trends don’t look like temperature trends.<br />

• Typically, people believe that as global temperatures<br />

increase so will precipitation, but the trick is that the<br />

average precipitation is what is increasing.<br />

• We also see precipitation decreasing in areas that are<br />

already somewhat dry such as the Sahara desert. While<br />

at first this doesn’t seem like a bad thing, it should be<br />

noted that the area is expanding such that areas that<br />

once could support crops may now be having problems<br />
