Fifty years ago National Geographic published this map of Arctic sea ice.
This is the current map from DMI.
There is more ice in the Beaufort and Chukchi Seas now and less in the East Siberian Sea
The 1985 DOE report showed that ice extent in 1971 was about 10% higher than 1960.
In 1958 the New York Times reported rapidly melting ice and predicted an ice-free Arctic in a generation. They said the ice was two meters thick.
The ice is currently about two meters thick.
