Polar Ice, To Melt or Not to Melt

Updated NASA Data: Global Warming Not Causing Any Polar Ice Retreat - Forbes:

This is ONE data point from NASA. To summarize:

  • All our DETAILED and GLOBAL temperature, Co2, etc measurements are VERY recent in terms of climate data. "1979" before we had significant sensors in space to start to gather true global data. 
  • 1960-1980 were a relatively cool climate period -- thus the thoughts in the 1970s that we might be entering another ice age. 
  • The Little Ice Age, roughly 1300-1870 added a lot to glaciers -- especially mountain glaciers. Nearly all of our even rough measurements from stations WIDELY scattered around the globe comes from post 1870 -- so that also tends to show "warming" ... from a very cold period. 
  • The accuracy of our information, even the space based information is "within a degree or two" or "a percentage or two" on things like ice coverage. 
So, given all that, it appears that when one considers TOTAL POLAR ICE -- sea ice and glacial ice, at the poles, we are back to within 5% of 1979, and thus the headline "No Polar Ice Retreat". Our accuracy isn't that good, and 1979 as a "base year" for ice extent is questionable at best.

Forbes is conservative -- the mainline media is not likely to pick this up, because it doesn't fit with the "warming crisis" narrative that they and "The Party" (D) hold to. Just last week, BO was blaming ISIL on Global Warming, so don't expect the MSM to be casting any doubts on it's total truth anytime soon!
