In addition there is also evidence of increased flow through the Bering Strait, in this case as much as 50%. And we aren't talking a little bit of water, we're talking .4 Sverdrups (a measure of flow, 1 Sverdrup is 1 million cubic meters per second, the entire global input of fresh water from rivers to the ocean is equal to about 1.2 sverdrup) or 400,000 cubic meters per second increase. 

To make the argument that there is little effect on SLR from that much water is untenable.
