Caught lying!-----Canadian Arctic ice coverage before there were satellites - Climate Discussion Nexus

Canadian Arctic ice coverage before there were satellites - Climate Discussion Nexus - Science Notes
"For years we have been treated to graphs showing the decline of Arctic sea ice based on satellite measurements, which began in 1979. 

The Canadian Ice Service also maintains detailed data on annual sea ice coverage throughout the Canadian Arctic and sure enough, the record since 1979 looks like the satellite record for the Arctic as a whole with a clear downward trend:

• But here’s something interesting: the Canadian Ice Service data don’t start in 1979, they start back in 1971. And you’ll never guess what happens when we add in the earlier data. At least alarmists won’t. Because it’s that the trend vanishes.

Here’s what the longer series looks like, and it’s quite a surprise:

Despite the supposedly “record” low ice cover in recent years, they’re not even records compared to the early 1970s, never mind earlier in the 20th century...
