Increased stratospheric greenhouse gases could delay recovery of the ozone hole and of ozone loss at southern mid-latitudes
Stratospheric H2O is increasing, and may be responsible for a large part of the observed cooling of the lower stratosphere. Further cooling will lead to more PSCs in the edge of the Antarctic stratospheric vortex in spring, though not in the vortex core which already becomes cold enough for near-con...
