    •  I agree with your points above. (0+ / 0-)

      This Nature paper is from 1989 when methane was growing at a much faster rate.  This field of science (stratospheric and mesospheric clouds) has also advanced in the past decade.  You can find many papers on the mechanisms that create noctilucent clouds -- and yes, methane is important.

      Interestingly, since about 1990 the methane growth rate has slowed.  Here is a time series from Barrow, Alaska where many scientists are anxiously watching for permafrost sources of methane.

      You can find a bunch of methane timeseries at the NOAA/ESRL website.
