That's rather a smartarse response and you know it.
As it happens, the ice caps are not melting away. The Arctic is slightly below the long term average while the Antarctic is slightly above. Did you know this?
Out of the 75% of the stations in the USA surveyed, only 11% fit the USHCN's own criteria for a category 1 (well sited) surfacestation, with the majority being category 4 and 5 stations, like the ones I showed in those photos. These stations are the ones that are used to compile the historical temperature trend across the USA - does this not concern you even a little bit?
Another important issue that received a brief mention in this thread was that of Urban Heat Island (UHI) effect. NASA's Goddard Institute of Space Studies (GISS) which issues one of the four main world temperature metrics, applies an algorithm to the data as an adjustment for UHI, but this is a measly 0.5 degrees F. Actual measurements of the UHI effect across a city, taken by temperature transects, show that the actual temperature difference between the centre of a city and surrounding rural land, is closer to 5 - 6 deg F. Anthony Watts recently did such transects across Reno, and came up with these numbers, while others have recorded a similar range of numbers across different cities. As cities have grown, the temperatures have grown as well compared to adjacent areas that have remained rural. And incidentally GISS has steadily dropped the number of reporting stations for their metric - yes dropped, not increased - and surprise surprise, most of the dropped sites have been those in rural areas, and not ones in cities and at airports.
I posed a question to Richard Choi, very early in this thread, which he has not answered - in fact no-one has who is a supporter of the Anthropogenic Global Warming argument - and that was to please tell me the current concentration of Carbon Dioxide in the atmosphere, without recourse to Google. Do you know it Jack?
