I could not find a link on Walleyes post, could you post a link to the source of that graph?The graph you linked doesn't show sea ice levels. It shows sea ice export rates through the Fram Strait.Why do you say that? It's been much lower in the last 50 years.
The lowest it has been in recorded history was in 2007.
Oh, I wouldn't bet on that. The record keeping started in 1970 and amazingly enough those records are never shown but they were lower than the present day, and by quite a bit. And then we have this study, one of many that say otherwise.
Arctic Ocean sea ice proxies generally suggest a reduction in sea ice during parts of the early and middle Holocene (∼6000–10,000 years BP) compared to present day conditions. This sea ice minimum has been attributed to the northern hemisphere Early Holocene Insolation Maximum (EHIM) associated with Earth's orbital cycles. Here we investigate the transient effect of insolation variations during the final part of the last glaciation and the Holocene by means of continuous climate simulations with the coupled atmosphere–sea ice–ocean column model CCAM. We show that the increased insolation during EHIM has the potential to push the Arctic Ocean sea ice cover into a regime dominated by seasonal ice, i.e. ice free summers. The strong sea ice thickness response is caused by the positive sea ice albedo feedback. Studies of the GRIP ice cores and high latitude North Atlantic sediment cores show that the Bølling–Allerød period (c. 12,700–14,700 years BP) was a climatically unstable period in the northern high latitudes and we speculate that this instability may be linked to dual stability modes of the Arctic sea ice cover characterized by e.g. transitions between periods with and without perennial sea ice cover.

Proxies are not part of recorded human history, though they are part of natural history. Moreover, the sea ice minimum discussed in the paper above is associated with Earth's orbital cycles. The present day reduction in Arctic sea ice is not.
One of many graphs that show lower sea ice in the late 60's, early 70's. Then there was a deluge of sea ice that topped out in 1978. Funny how your alarmist graphs never include the earlier dated material.
