We have been bombarded for years with graphs like the one below, presented as evidence of Arctic doom. The graphs conveniently start in 1979, which was the peak year of the last century.
Thanks to the work of skeptics, two key government documents have been dug up – which tell us that Arctic sea ice extent was much lower prior to 1979.
In 1990, the IPCC published the graph below based on NOAA data. It shows us that Arctic ice extent in 1974 was almost two million km^2 less than 1979
This tells us that 1974 Arctic ice coverage was similar to current coverage, which is also about two million km^2 less than 1979. But it is worse than it seems. The CIA published the document below in 1974, which tell us that prior to 1974, Arctic ice coverage was an additional 10% lower.
Deducting another 10% puts us back to about 2007 levels of ice. If the IPCC, NOAA and the CIA know about this, why is the information being obfuscated?
