So, what was happening with global weather during the week that encompassed July 8 - 12? Gee, let me think -- IT WAS RECORD BREAKING HOT. It wasn't just hot in my part of the US (midwest), it was hot EVERYWHERE in the US. Now what happens to all that hot air (har!) -- it drifts to the east/northeast doesn't it? And where is Greenland located? Gee - to the east/northeast of the US. Did any of these scientists check what the ground temperatures were in Greenland during this time of "sudden and strange melt?" Well, that's my totally unexpert guess. Duh!
