You were doing so well until you forgot to acknowledge that the science has already spoken. I have not assumed anything mjp. I have USED your own sources of data to prove to you that WV has not increased. And for where it counts Stratosphere temps have not declined. Pretty hard to argue against it.
So the OBVIOUS question is mjp2 and other followers. Do you refute NOAAs assessment that water vapour content has decreased;
and do you refute NASA assessment that the net effect of of WV in the stratosphere
will result in a net loss of OZONE.

Statements from your favourite sources of data
Points raised yesterday perhaps you have overlooked?
1. NOAA have clearly stated that Water Vapour is DECREASING in the stratosphere -Solomon paper. linked above in earlier post.
2.The IPCC have acknowledged that they are unable to detect any increase in WV in the Stratosphere. Both Cannot be disputed. Links supplied already above
Bellcurve will try no doubt with another appeal to authority. phff and he claims he is a critical thinker. Pigs do fly dontr they Bellcurve!
3. The IPCC and NASA have clearly stated that Water Vapour breakdown OZONE. You have stated that O3 is increasing. Thus it MUST be inferred that WV is not increasing. You have no option BUT to agree. yet you ARGUE till you are BLACK and BLUE that WV is increasing? You cannot have it both ways mjp.
4. Between NASA, IPCC, NOAA and others they state that METHANE oxidation contributes as low as 1/3 to as high as 2/3 of all water Vapour in the Stratosphere. The rest from natural uplift That their alone is a major hurdle for you to jump over mate. Is Methane increasing? Or is its ozone destroying capabilities only a smidgen of what is claimed?
5. Direct quote from the IPCC, relates to point 1. -
AR4 reported that stratospheric H2O vapour showed significant long-term variability and an upward trend over the last half of the 20th century, but no net increase since 1996. This updated assessment finds large interannual variations that have been observed by independent measurement techniques, but no significant net changes since 1996.
6.. And yes mjp2 Water Vapour did take off in the late 20th Century. There was an abundance of it in the troposphere and the stratosphere. Radio Sonde data clearly shows it. I 100% agree with YOU. But what happened after that mjp. The strato stopped cooling. Why? because of Ozone increase? Maybe O3 increase is a reflection on a lowering of water vapour in the stratosphere. NOAA clearly STATED in the Solomon paper a decrease in water Vapour!
7. A NASA paper I did not pull out yesterday. A dmittingly I was a tad confused with the wording. But there is one part that is clear as mud highlighted in RED BELOW. This is what they had to say in 2001

Increasing greenhouse gases cool the stratosphere, though, slowing down the rates of chemical reactions that destroy ozone. This leads to more ozone overall (though the opposite effect is seen in the chemistry that controls the polar ozone holes, which proceeds faster as temperatures decrease). We find, however, that the increasing water trend exerts an even stronger influence, leading to a net loss of ozone due to the interactions with greenhouse gases and water vapor (Figure 2). A wetter stratosphere also affects surface climate, because both water vapor and ozone are greenhouse gases, which trap heat leaving the Earth. Increased water vapor in the stratosphere makes it warmer on the ground by trapping heat, while the ozone loss makes it colder on the ground. However, water vapor has a much larger effect, so that overall the changes increase global warming by about 10-15%.
So to finish off lets have a look at Water Vapour and the highest uppermost WV data available for the equatorial regions. Just where we would expect to see the water vapour penetrating the stratosphere from those deep convective thunderstorm clouds.
Yes. I agree with you. WV surged in the late 20th century.
