The last time I flew to Europe was in 2009 and we flew over Greenland. Even then I remember seeing lots of large rivers of ice melt all across the island. Seems like Greenland is going to end up being iceless barren rock soon. And, the Gulf Stream, apparently, is possibly/probably very much in danger of collapsing sometime soon. The problem with the Gulf Stream is a problem that has been well known for at least a couple of decades but seems to have been mostly ignored and not reported much until very recently.
