The Strange "Global Warming" of the Antarctic Peninsula
Franzke, C. 2013. Significant reduction of cold temperature extremes at Faraday/Vernadsky station in the Antarctic Peninsula. International Journal of Climatology 33: 1070-1078.
"Typically," in the words of Franzke, "one would expect that a significant warming also leads to absolute warmer temperatures and not just to a reduction in cold temperatures." But the latter is precisely what has happened at the Faraday/Vernadsky weather station: it's only the colder temperatures that have gotten warmer.
Franzke also notes that "global climate projections suggest that the frequency of hot extremes will increase due to global warming," citing Meehl et al. (2007). The models therefore also miss the mark as it applies to the Antarctic Peninsula, and to other parts of the world as well (see, for example, Kukla and Karl, 1993; Easterling et al., 1997). And thus it is that Franzke writes that the data from the Antarctic Peninsula "are somewhat at odds with the general opinion that global warming leads to more frequent and larger extremes." In fact, on the Antarctic Peninsula, Franzke finds that "annual maximum temperatures are almost constant over the last six decades," while minimum temperatures have actually gotten less extreme.
And so it is that there may not have been even a relative heat wave on the Antarctic Peninsula since the start of temperature measurements there some six and a half decades ago.
