In some parts of Asia, Africa and South America, the researchers identified data gaps which prevented them from characterizing ozone pollution exposure patterns. However, overall, Southern Hemisphere sites tend to have lower ozone pollution levels, and fewer days above 70 ppb. Source: University of Leicester.

Plants consume carbon dioxide—a significant greenhouse gas—in the process of photosynthesis. Plants that release less water also take less of it from the environment. The increase in runoff is even larger when nitrogen is limited and environments are exposed to high ozone levels ,” said Felzer. Cronin, J. Melillo, D.
