Which effect arises when increased atmospheric CO2 alters the stratospheric temperature gradient?

💡 Explanation

Decreasing temperature gradient will weaken the polar vortex because it reduces the Coriolis effect which forms the vortex; thus, less stable circulation results. Therefore, decreased polar vortex stability is expected rather than other ocean system effects due to atmospheric stratification changes.
