Unable to find that article tinnitus.
So i just google troposphere relative humidity. i thought i would look at the sites that no one would dare question.

I did find this one though from NASA
EXTRACT
Using instruments aboard NASA’s Upper Atmosphere Research Satellite (UARS), scientists measured humidity high in the atmosphere. The researchers compared those humidity measurements with sea surface temperature records. Based upon these observations, scientists then measured the feedback between rising temperatures and increasing concentrations of water vapor in the atmosphere. This crucial variable in climate change estimates had previously been based on speculation and modelling, but not direct observations. The scientists found that most climate models have been overestimating the amount of water vapor entering the atmosphere as the Earth’s surface warms. (For more details, read the NASA press release.)

for some reason NASA have removed that article now???

And this from Skeptical science

Looking at all this evidence, the conclusion is, well, a little unsatisfying - there is still much uncertainty in the long-term trend. It's hard when the short-term variability is nearly an order of magnitude greater than the long-term trend. Weather balloons and satellites do a good job of measuring short-term changes and indeed find a hot spot over monthly timescales. There is some evidence of a hot spot over timeframes of decades but there's still much work to be done in this department. Conversely, the data isn't conclusive enough to unequivocally say there is no hot spot.
