The first problem is those words ‘green’ and ‘ice free’. According to Ms Barclay, ‘ice free’ refers to ground covered with less than 500 metres thick. So ‘green, ice-free land’ could refer to land covered with nearly third of a mile thickness of ice – thicker than the Empire State Building is high! I put it to Ms Barclay that this isn’t what most people would think of as ‘ice free’.
“Yes, I can see why you would see that as misleading” she admitted, after a very long pause. And ‘green’? To me (and I would guess everyone else) I think of bleak Greenlandic hillsides covered with grass or at least moss, perhaps a few grazing sheep. It turns out ‘green’ refers just to the printing colour chosen by the cartographers to indicate low-altitude land, and not its colour at all. Which is, er, white.
