There is also growing understanding of the links between atmospheric problems such as local air pollution, acid rain, global climate change and stratospheric ozone depletion.

I don't know if I am confusing the issue here between ozone and climate change.

I don't know if I am confusing the issue here between ozone and climate change.

Warming must occur below the tropopause to increase the net LW flux out of the tropopause to balance the tropopause - level forcing; there is some feedback at that point as the stratosphere is «forced» by the fraction of that increase which it absorbs, and a fraction of that is transfered back to the tropopause level — for an optically thick stratosphere that could be significant, but I think it may be minor for the Earth as it is (while CO2 optical thickness of the stratosphere alone is large near the center of the band, most of the wavelengths in which the stratosphere is not transparent have a more moderate optical thickness on the order of 1 (mainly from stratospheric water vapor; stratospheric ozone makes a contribution over a narrow wavelength band, reaching somewhat larger optical thickness than stratospheric water vapor)(in the limit of an optically thin stratosphere at most wavelengths where the stratosphere is not transparent, changes in the net flux out of the stratosphere caused by stratospheric warming or cooling will tend to be evenly split between upward at TOA and downward at the tropopause; with greater optically thickness over a larger fraction of optically - significant wavelengths, the distribution of warming or cooling within the stratosphere will affect how such a change is distributed, and it would even be possible for stratospheric adjustment to have opposite effects on the downward flux at the tropopause and the upward flux at TOA).

While the three ozone databases all show a reduction in ozone in the lower tropical stratosphere, the magnitude of this change differs substantially between them and occurs against a backdrop of much larger interannual variability.

In the meantime, Murry Salby has at least 8 papers in the past decade on the importance of the QBO on the stratosphere, and notes the» climate sensitivities of temperature and ozone describe random changes between years, introduced by anomalous EP flux and the QBO».

After all, the scientific assessment that the safe level of ozone should be lowered to somewhere between 60 and 70 parts per billion hasn't changed.

The evolution of the latter, intimately associated with the evolution of the ozone content of the air between 400 hPa and 50 hPa, is associated with what is described as the Antarctic Oscillation, that I argue is the most influential mode of natural climate change globally.

Because the interactions between ozone, temperature, mixing rates, water vapor (and other chemicals) are complex and multi-faceted, accurate predictions of the future ozone layer's health in the face of predicted or unexpected changes are difficult.

For tropospheric ozone (driven by the changes in NOx, VOC, OC and methane emissions, along with changes in climate conditions), there is a clear difference between the RCPs.

The climate system is highly non-linear8 and relatively little is known about the effect on temperature changes resulting from human contributions to the changing three - dimensional distributions of ozone and aerosols, either or both of which may have been partially responsible for the observed discrepancy between surface and lower to mid-tropospheric temperature changes.

To test this theory, we decided to see if there was any relationship between the concentration of ozone in the ozone layer, and the phase change conditions.

Possible correlations between solar ultraviolet variability and climate change have previously been explained in terms of changes in ozone heating influencing stratospheric weather.

The cooling of the sea between 1948 and warming thereafter are entirely accounted for in the shift in the mass of the atmosphere that lies behind the change in wind strength and the flux in ozone that causes the cloud cover to change.

There is a complex relationship between ozone loss and climate change.

Changes in clouds between these two runs should be driven by the aerosols (with a minor contribution from ozone via a semi-direct local heating effect).
