Ozone depletion can contribute to global warming, making the choice that indicates this statement is true accurate. The ozone layer, found in the Earth's stratosphere, serves as a shield that absorbs the majority of the sun's harmful ultraviolet radiation. When ozone levels decrease due to human-made chemicals, such as chlorofluorocarbons (CFCs), more ultraviolet light reaches the Earth's surface.

This increase in ultraviolet radiation can lead to warming in certain areas of the atmosphere, as well as increased greenhouse gas effects. Furthermore, the breakdown of ozone can indirectly affect climate patterns by altering atmospheric circulation and the distribution of temperature.

While the relationship between ozone depletion and global warming is complex, the consensus in climate science indicates that there are connections between these phenomena. Thus, the assertion that ozone depletion contributes to global warming is supported by scientific understanding, making the first option the most accurate response to the question.
