AbstractThe impact of ozone-depleting substances on global lower-stratospheric temperature trends is widely recognized. In the tropics, however, understanding lower-stratospheric temperature trends has proven more challenging. While the tropical lower-stratospheric cooling observed from 1979 to 1997 has been linked to tropical ozone decreases, those ozone trends cannot be of chemical origin, as active chlorine is not abundant in the tropical lower stratosphere. The 1979–97 tropical ozone trends…

Radiosondes Show That After Decades of Cooling, the Lower Stratosphere Is Now Warming
Since the mid‐twentieth century, radiosonde and satellite measurements show that the troposphere has warmed and the stratosphere has cooled. These changes are primarily due to increasing

Significant Weakening of Brewer‐Dobson Circulation Trends Over the 21st Century as a Consequence of the Montreal Protocol
It is well established that increasing greenhouse gases, notably CO2, will cause an acceleration of the stratospheric Brewer‐Dobson circulation (BDC) by the end of this century. We here present
Dependence of model-simulated response to ozone depletion on stratospheric polar vortex climatology†
We contrast the responses to ozone depletion in two climate models: CAM3 and GFDL AM3. Although both models are forced with identical ozone concentration changes, the stratospheric cooling simulated
Large Impacts, Past and Future, of Ozone‐Depleting Substances on Brewer‐Dobson Circulation Trends: A Multimodel Assessment
TLDR
It is found that, as a consequence of the Montreal Protocol, decreasing concentrations of ozone-depleting substances in coming decades will strongly decelerate the BDC until the year 2080, reducing the age-of-air trends by more than half, and will thus substantially mitigate the impact of increasing CO2.

TLDR
In model simulations, the cooling of the stratosphere from 1979 to present is mostly driven by changes in GHG concentrations in the middle and upper stratosphere and by GHG and ODS changes in the lower stratosphere.
