Arctic sea ice has reduced drastically over the past few decades, recognized in both satellite observations and model simulations8,10,11. Since 1980, the sea-ice cover has had a mean annual areal reduction of ~20% and an even stronger decrease of ~30% in September7. This decrease in sea ice is also suggested to be the driver of frequent cold extremes over Eurasia in the past two decades12. Historical observations spanning the last few decades are deficient in length to decipher the processes of accelerated sea-ice retreat, thus longer-term and high-resolution proxy records of paleoenvironmental changes are needed. During transition from the last deglacial to the Holocene, the climate system underwent numerous abrupt changes, particularly the Bølling/Allerød (B/A) interstadial and the Younger Dryas (YD) stadial. The Holocene, not concluded yet, has experienced a significantly warmer period during its early stage (Early Holocene Thermal Maximum)13. Causes of the abrupt climate change are not fully understood, hence special emphasis on the transition from the deglacial into the Holocene is of significance to understand the forcing mechanisms of the climate system. In this context, the Arctic marginal seas characterized by strong seasonal variability in sea-ice cover, primary productivity, and terrigenous (riverine) input are very sensitive to environmental changes and thus of major importance for paleoclimate reconstructions. One of these marginal seas is the Beaufort Sea (Fig. 1), which we focus on in this paper. www.nature.com/articles/s43247-020-00028-z

"Surprise! Surprise! Any Greenland melting is….volcanic No, it is not a surprise. This is what I’ve been saying for years. The Greenland ice is melting from below.
“Newly Discovered Greenland Hot Rock Mantle Plume Drives Thermal Activities in the Arctic, “A team of researchers discovered a flow of hot rocks, known as a mantle plume, rising from the core-mantle boundary beneath central Greenland that melts the ice from below (emphasis added).
“The results of their two-part study were published in the Journal of Geophysical Research.
“Knowledge about the Greenland plume will bolster our understanding of volcanic activities in these regions and the problematic issue of global sea-level rising caused by the melting of the Greenland ice sheet,” said Dr. Genti Toyokuni, co-author of the studies."More here: iowaclimate.org/2020/12/26/surprise-surprise-any-greenland-melting-is-volcanic/

AND MIGHT explain the continual warm ocean anomalies we've seen north of Iceland over the last decade in CLIMATE4YOU. They will not be happy in LaLa Land. "Surprise! Surprise!

so these didn't happen when the ice was more extensive such as during the period 60 to 80. BS!
I call region as its once again an indisputable hypothesis.

I'd have more respect if they'd forecast ssw and blocking as a side effect of warming instead, they're just looking for reasons to explain events. I suspect they actually know FA about how the atmosphere works!
