You tell me mjp
Is methane a major source for stratosphere water vapour. The IPCC think so
Although methane oxidation is a major source of water in the stratosphere, and has been increasing over the industrial period, the noted stratospheric trend in water vapour is too large to attribute to methane oxidation alone
So what are you left with to describe the decrease in water vapour.
Slowing of methane emissions or a slowing of water vapour.
Again take your pick. I dont give a rats. the finger prints of your science are flawed. It is shot to pieces here mate
