Simply put, the warmer the air, the more moisture it can hold and the more moisture in the atmosphere, the greater the potential precipitation (either as snow, ice or rain depending on the temperature of the air).

True - But this is not happening...

Whereupon the Clown Prince offers up tidbits from his (I presume) favorite Denialist/Obfuscationist sources.

Sad, really. Quoting directly from the abstract of the paper GWPF/Ajax cited:

Trends since 1947 indicate that the warming of temperatures has coincided with increases in dewpoints and a moistening of specific humidity. This moistening is especially pronounced during the summer in the Midwest. For the nation, trends in relative humidity show little change for the period 1947–2010, during which these data are more homogeneous. Moistening has occurred throughout the central United States while other regions have experienced drying.

(Pssst, Ajax, you might wanna study up on the terms relative humidity and specific humidity to understand their different meanings.)

Then, of course there's a reference to NOAA and "atmospheric humidity." The chart provided doesn't link back to any text.

Well, here's a direct NOAA reference that indicates specific humidity is RISING:

And now for those genuinely interested in actual science, here's a nice little summary:

To claim that humidity is decreasing requires you ignore a multitude of independent reanalyses that all show increasing humidity. It requires you accept a flawed reanalysis that even its own authors express caution about. It fails to explain how we can have short-term positive feedback and long-term negative feedback. In short, to insist that humidity is decreasing is to neglect the full body of evidence.

Clown on, Ajax, clown on.
