If we believe Solomons
findings stratospheric water vapor was responsible for a big amount of warming since 1979 and even for about 25 % less warming since about 2000.
Not exact matches
These
findings are not sensitive to a wide range of assumptions, including the time series used to measure temperature, the omission of black carbon and
stratospheric water vapor, and uncertainty about anthropogenic sulfur emissions and its effect on radiative forcing (SI Appendix: Sections 2.4 — 7).
The use of
water vapor is also misleading — the
findings of Solomon did not include any claim that
stratospheric water vapor was unrelated to the concentration of other GHGs, only that it had declined recently (perhaps) for unknown reasons.
This modell shurely will not include the new
findings of Susan Solomon regarding
stratospheric water vapor and it's influence to global temperatures.
A few years later, methane levels were indeed
found to be rising, and the increase in
stratospheric water vapor was confirmed in 1995.
