Arctic sea ice extent averaged over January 2011 was 13.55 million square kilometers (5.23 million square miles). This was the lowest January ice extent recorded since satellite records began in 1979. It was 50,000 square kilometers (19,300 square miles) below the record low of 13.60 million square kilometers (5.25 million square miles), set in 2006, and 1.27 million square kilometers (490,000 square miles) below the 1979 to 2000 average. Ice extent in January 2011 remained unusually low in Hudson Bay, Hudson Strait (between southern Baffin Island and Labrador), and Davis Strait (between Baffin Island and Greenland). Normally, these areas freeze over by late November, but this year Hudson Bay did not completely freeze over until mid-January. The Labrador Sea remains largely ice-free.

I see arctic was spelled correctly in this article................
Your level of discourse is apparent when all you have is comments on minor typos a week later.
I'm just ribbing you in the spelling error, we all make them. However your claims about arctic sensors did demonstrate a serious lack of knowledge.
My point remains. If you think there are Arctic sensors away from human populations in remote highland areas that give true readings of of land temperatures, then describe where they are and how they compare to the sensors in the coastal populated areas. The Grrenalnd Nuuk weather station temperature measurements are extrapolated out over hundreds of sqaure miles.
I gave you several examples. Now explain how the surface temperature record correlates with the satellite record if you believe surface temperatures are skewed by the urban heat island effect. Perhaps the satellites are located too close to stars?
I gave you several examples. No you didn't. You just posted a chart saying there was no diferrence without giving specific sites. Here is a well maintained and well sited USHCN station: Here is a not-so-well maintained or well sited USHCN station:
i've asked you three times now to explain how the satellite record correlates with the land record if the land record is skewed. When are you done with that one, please explain how the surface land record correlates with the ocean record? At some point you need to stop reading right-wing blogs and Anthony Watts and learn to think for yourself. Source: http://www.skepticalscience.com/surface-temperature-measurements-advanced.htm

What about satellite measurements of temperatures in the lower troposphere? There are two widely cited analyses of temperature trends from the MSU sensor on NOAA's polar orbiting earth observation satellites, one from Remote Sensing Systems (RSS) and one from the University of Alabama-Huntsville (UAH). These data only go back to 1979, but they do provide a good comparison to the surface temperature data over the past three decades. Figure 7 shows a comparison of land, ocean, and global temperature data from the surface reconstructions (averaging the multiple analyses shown in figs. 3 and 4) and from satellites (averaging the results from RSS and UAH):
