Offhand, I don't know of any graphs showing this greenhouse impact of water vapor on
temperatures over short time frames, but it generally falls into the realm of «common knowledge».
Actually Fielding's use of that graph is quite informative of how denialist arguments are
framed — the selected bit of a selected graph (and don't mention the fastest warming region on the planet being left out of that data set), or the complete passing
over of
short term variability vs longer term trends, or the other measures and indicators of climate change from ocean heat content and sea levels to changes in ice sheets and minimum sea ice levels, or the passing
over of issues like lag
time between emissions and effects on
temperatures... etc..
