The Arctic Sea Ice melting

Thanks to No Tricks Zone for this:

When one hears or reads the reports about the Arctic sea ice, it helps to remember that satellite measurement did not begin until 1979. Thus we have data only for a period of just over 30 years. This barely suffices to fulfil the gladly used “climate definition” of a minimum period of 30 years. So we can’t avoid having a suspicious feeling, as we ask what did the sea ice do before satellite measurement began? Can we just simply skip over this and simply add the notation that we just don’t know much about it? Of course not. That would be too easy. Before the days of satellite measurement, ships travelled in the Arctic and brought back information about sea ice cover in the region.
In the following chronology, we present some of these reports. You’ll be amazed by what was observed.

1922 The Pittsburgh Press: “Extraordinary warmth in the Arctic during the last few years. Polar ice sheet to melt down? “Source: Real Science, The Mail.
1923 Fishermen, seal hunters and explorers report on unusually high temperatures around Spitzbergen and the East Arctic Ocean. The Daily News from Perth speculated on whether the sea ice in the Arctic Ocean would soon melt away as a result of a “radical climate change”. Source: Real Science.

At the end of the 1930s, Soviet scientists noticed that for an extended time period it even had been 6°C warmer than during the Nansens ice drift, and a few degrees warmer than today. Source: Donner + Doria.
