- The greenhouse gases produces near-surface global warming. This fact is expected to cool the stratosphere, and in turn, it is expected to produce a relative increase in stratospheric ozone depletion.
- Conversely, ozone is a radiative forcing of the climate system. There are two opposing effects. On the one hand, ozone increases in the troposphere from pollution associated with human activities leads to a warming of Earth’s surface. In contrast, stratospheric ozone depletion represents a small negative forcing, which leads to cooling of Earth’s surface.
