NSIDC wants us to believe that satellite measurements began in 1979.
But satellite records go back much further, and showed ice gain in the 12 years prior to 1979. Paul Homewood found this quote from the CRU Director HH Lamb
Kukla & Kukla (1974) report that the area of snow and ice, integrated over the year across the Northern Hemisphere, was 12% more in 1973 than in 1967, when the first satellite surveys were made.
From 1974 to 1979, the IPCC showed another large gain, based on satellite data which NSIDC ignores.
If NSIDC showed the complete satellite data set, people would know that Arctic behavior was cyclical, as we can see in the original GISS temperature graph from Iceland
Hansen of course didn’t want us to know about this cyclical behavior, so he got…
