Is interesting, and germane to our discussion. But I got a totally different interpretation out of it than could these scientists.

1) EAIS and WAIS are continental glaciers meaning that they don't move much because there is no change in land slope beneath them. At the distal edges of these glaciers, however, the land drops into the sea, and sometimes at high angles. Here there are valley glaciers, and that is what is pictured in the article:

Land with topography allows valley glaciers to flow due to 1) growth and 2) basal slip. Basal slip is when there is a lubricated layer of water or slush between the land surface and the bottom side of the glacier. Growth of ice on top of the glacier is controlled by the overall glacial budget each year over many (thousands of years) basically accumulation (added snow and eventual ice in cool times) versus wastage (removal of ice via melt water in warm times).

All this to say, looking at valley glaciers on the edge of the ice sheet is not the best way to study the continental glacier that is WAIS or EAIS. In fact, I think the scale is too big to even look at a continental glacier and understand what is happening, so scientists turn to things that would track temp globally, which is probably why everyone is stuck on what greenhouse gases could do versus evidence of what they are doing, because the first thing that needs to happen for any type of big change to happen is ice sheets need to melt.

It's hard because continental ice sheets spread due to the slow plastic flow of ice. Ice is like a slow moving fluid, so at a certain height a pile of ice will start to flow down to its edges, kind of like how you can't make a sandcastle of dry sand high without increasing its base. So how do we track this over time and how do we know what's going on? Being humans and being a really difficult place to travel to and study.

All this to say...yes...I know about glaciers.

Whose to say that this increase of flow is due to the overall growing of the ice sheets busting out the seams? The seams being the edges of Antartica and their valley glaciers, the ones that are supposed to move?
