You are confusing “area” and “extent.” Look at your picture for extent. It is not below 5 million sq k. What you say is correct for area, a different and better measure but one that we have much less data for

Could we be seeing a walker cell forming between the ever more ice free Arctic ocean and the katabatic winds caused by the cooling of air by the ice sheet. If we do (or have already got) such a link, heat is imported from a distant (not very distant) source to the ice. The dynamics are totally different from sun hitting snow and being reflected or hitting clear ice and having to heat up a depth of ice to 0 degrees before melting can start. Here we have a constant source of heat applied to the very surface of the ice. Read chapter 42 of plains of passage. It is a novel but Jean Auel did her homework.
