Sea ice records go a lot further back than 1978.
Given the relatively cool Northern Hemisphere winter, there has been a good freeze of the Arctic Ocean, but it's mostly first-year ice. I'll be curious to see how much the Arctic sea ice melts this summer.
Not sat data...the other data was gathered by ships and coastal observations and thus is like comparing apples to oranges.
I’m just Hoping we have summer. I want Change.
Come on, cogitator... you know damned well that those are reconstructions.
Plus, I note you’re cherry picking... How come you didn’t post that same site’s more recent, detailed record... the one showing the remarkable rebound in sea ice?
Then there’s that little matter of the Antarctic sea ice shattering the old records...
Looks like we are still coming out of the Little Ice Age.
