Hello Jurge,
I wish we could have more meaningful debates and conversations. I don't make it a habit to state things that are false, as what drives me is truth and objectivity. We can disagree with each other and show our work and sometimes we may learn from each other. I actually respect you and your work very much. Let's say its been influential for me.
The IEEE paper published in 2014 shows that NIMBUS data was able to be used to derive earlier sea ice extent data and the results show that the minimum in 1966 was 15.9m km2. Whenever you look at any data set relating to climate over the years I have learned to check the time periods covered as most likely these are cherry picked periods used to make data fit a narrative.
The best policy and path forward for humanity is logically fully dependent upon the best unbiased data and currently the pendulum is swinging too far. My only goal is objectivity and diversity in opinions serves to bolster scientific objectivity. So I am happy to discuss these issues with you openly. I might post something that seems strange simply because I have three day jobs and don't have time to show my work. I am happy to share my sources with you so we can discuss.

Anomalous Variability in Antarctic Sea Ice Extents
During the 1960s With the Use of Nimbus Data David W. Gallaher, G. Garrett Campbell, and Walter N. Meier
Abstract—The Nimbus I, II, and III satellites provide a new op- portunity for climate studies in the 1960s. The rescue of the visible and infrared imager data resulted in the utilization of the early Nimbus data to determine sea ice extent. A qualitative analysis of the early NASA Nimbus missions has revealed Antarctic sea ice extents that are signi¿cant larger and smaller than the his- toric 1979–2012 passive microwave record. The September 1964 ice mean area is 19.7x10 km ± 0.3x10 km . This is more the 250,000 km greater than the 19.44x10 km seen in the new 2012 historic maximum. However, in August 1966 the maximum sea ice extent fell to 15.9x10 km ± 0.3x10 km . This is more than 1.5x10 km below the passive microwave record of 17.5x10 km set in September of 1986. This variation between 1964 and 1966 represents a change of maximum sea ice of over 3x10 km in just two years. These inter-annual variations while large, are small when compared to the Antarctic seasonal cycle.
