Well if you're talking about that phrase, you'll note that I didn't say Relative Humidity. I said Humidity (absolute). If it's not that, I don't know what you're talking about.

The partial pressure of water in the Antarctic atmophere, particularly katabatic winds, may be below the triple point pressure.

The phase diagram for water is a single component phase diagram. You've been talking about atmospheric pressure. In fact the partial pressure of air is irrelevant to the phase diagram because the P that we're referring to in the phase diagram is the partial pressure of water.

(Remamber the Gibbs Phase rule F=C-2 +P)

Is that what you mean?

If it is, then I don't think you thought of it yourself based on your earlier comments, but kudos for the "research" (phone a friend). 

Either way, you could have spared # of a highly technical argument, because in practice, he was perfectly correct.

I don't think he claims to be a scientist.

Just from here.  Enough to know that he has common sense.

Yes I have. I already explained it to you.

A new paper on Arctic Ice-
'Abstract. Understanding recent Arctic climate change requires detailed information on past changes, in particular on a regional scale. The extension of the depth–age relation of the Akademii Nauk (AN) ice core from Severnaya Zemlya (SZ) to the last 1100 yr provides new perspectives on past climate fluctuations in the Barents and Kara seas region. Here, we present the easternmost high-resolution ice-core climate proxy records (δ18O and sodium) from the Arctic. Multi-annual AN δ18O data as near-surface air-temperature proxies reveal major temperature changes over the last millennium, including the absolute minimum around 1800 and the unprecedented warming to a double-peak maximum in the early 20th century. The long-term cooling trend in δ18O is related to a decline in summer insolation but also to the growth of the AN ice cap as indicated by decreasing sodium concentrations. Neither a pronounced Medieval Climate Anomaly nor a Little Ice Age are detectable in the AN δ18O record. In contrast, there is evidence of several abrupt warming and cooling events, such as in the 15th and 16th centuries, partly accompanied by corresponding changes in sodium concentrations. These abrupt changes are assumed to be related to sea-ice cover variability in the Barents and Kara seas region, which might be caused by shifts in atmospheric circulation patterns. Our results indicate a significant impact of internal climate variability on Arctic climate change in the last millennium.

Shows a double peak warming spot in the 1920's to 40's that seem warmer than up to about 1998. So may be not as far back as thought.

Of course with massaged "data" from the models, anything is possible.
