The quote you have from Alastair (I think that's the spelling), Tim, comes from a later reply, not to his original post. My impression Karen was responding to the original not this one.

As for the text of his response.

"You may wish to look at some of the mass balance studies of the ice on Antarctica and Greenland. You will find that there is no consensus that either is loosing ice. The consensus is that increases in global temperatures (up to about 3 deg C.) melt the edges of the glaciers but lead to thickening of the glaciers at higher elevations due to increased precipitation.

I noted in my reply that the specific link made two arguments: (1) the ice continues to melt at the edges, no one disagrees with that; (2) the effects of increased precipitation in the interior are not clear--whether it's part of a pattern, random or what not. Or whether it matters.

So the phrased "mixed results", which appears elsewhere in that post, doesn't mean there is a data challenge to the "ice is melting" argument. Rather that the pattern, degree, or meaning of increased precipitation in the interior is not yet known.
