Has anyone ever wondered why the graphs of arctic sea ice extent always start in 1979? Even though satellite data exists back into the early 60's, and other records and proxies go back much further?
Do you think that 1979 is a random date, or represents a high or a low in arctic sea ice?
Same for Antarctica. Anyone know what years their records were set, and that the record max and min were only 2 years apart, and represent a 20% decline in two years. Actually, not true, the maximum record was broken again in recent years, contrary to popular belief, the minimum stands.
