Quizplus · Accepted Answer

Stratospheric ozone has a negative radiative forcing effect because it absorbs some of the incoming solar radiation before it reaches the Earth's surface, thereby reducing the amount of solar energy available for heating the planet. This effect has a cooling influence on the Earth's climate. Conversely, the other options listed have a positive radiative forcing effect, meaning that they trap heat in the atmosphere and contribute to global warming.
