You wrote about Artic ice: Lie. There are shipping records going back more than a hundred years and proxy records going back thousands.
You can’t compare satellite records to incomplete records from the past, especially since so many records were lost during WWII.
Here is an interesting history on the Arctic during that timeframe:
“The warming of the arctic seas has caused a diminishing of the arctic drift ice, which again has improved shipping conditions. In the 1907-1917 period Norwegian coal mines in Spitsbergen were able to load and export coal an average of 94 days each season, while 20 years later this period has been extended to 192 days. In 1878-80 Nordenskjold in the Vega was the first to navigate the North East Passage, but to do this he had to winter twice. In 1936 a convoy of fourteen Russian ships mode the trip in one season without encountering serious ice difficulties and during the last war this northern Sea route was used extensively by Soviet shipping. During 1942-45 even war ships, which are especially vulnerable to ice, were able to reach Thule without difficulty.
The seas around Greenland have also been remarkably open in later years. The east coast, which frequently remained completely blocked by pack-ice, in 1931-33 was almost free from ice.”“In 1941-42 the low-powered, 80 ton R.C.M.P. schooner St. Roch made the North West Passage for the first time from the Pacific to the Atlantic and again in 1944 in the opposite direction in only 87 days.”
We have shipping maps from those period.
They show that the ice melt then was no comparable to the present.
