The Greenland study is for only one glacier and is not a global indicator.
Never said that they did. But I think you would probably concede that the response glaciers will have some lag time. I would propose (hoping that an actual researcher might follow up) that the glaciers are now responding to the accelerated warming that has been noted in the surface record since about 1980. I would also propose that the Braithwaite study, because if covers a 1945-1995, is going to be weighted heavily for the no-trend period, so any trend appearing near the end of the record will be hard to detect.

It's the second largest ice cap in the world and it's in the high Arctic, where global warming models say the warming will be most intense. I think it bears watching. NASA is set to launch a laser altimeter satellite (Icesat) at the end of the year that is designed primarily to measure ice cap volume and changes. So we'll only have to wait 5 years or so for enough data to indicate a trend... (yawn)
