The Books Have Been Cooked, GW is actually GC

the initial reports of antartica ice sheet loss were corrected.



It also puts the kibosh on GRACE studies that suggested a net loss in Antarctica. Note there’s the mention of the “climate warming, consistent with model predictions” at the end of the report. They’d say the same thing if ICEsat had measured loss instead of gain, because as we’ve seen before, almost everything is consistent with warming and models no matter which direction it goes.

Here’s the video presentation. The report abstract follows.

I 've showed this too you before...

Abstract:

During 2003 to 2008, the mass gain of the Antarctic ice sheet from snow accumulation exceeded the mass loss from ice discharge by 49 Gt/yr (2.5% of input), as derived from ICESat laser measurements of elevation change. The net gain (86 Gt/yr) over the West Antarctic (WA) and East Antarctic ice sheets (WA and EA) is essentially unchanged from revised results for 1992 to 2001 from ERS radar altimetry.

Imbalances in individual drainage systems (DS) are large (-68% to +103% of input), as are temporal changes (-39% to +44%). The recent 90 Gt/yr loss from three DS (Pine Island, Thwaites-Smith, and Marie-Bryd Coast) of WA exceeds the earlier 61 Gt/yr loss, consistent with reports of accelerating ice flow and dynamic thinning. Similarly, the recent 24 Gt/yr loss from three DS in the Antarctic Peninsula (AP) is consistent with glacier accelerations following breakup of the Larsen B and other ice shelves. In contrast, net increases in the five other DS of WA and AP and three of the 16 DS in East Antarctica (EA) exceed the increased losses.

Alternate interpretations of the mass changes driven by accumulation variations are given using results from atmospheric-model re-analysis and a parameterization based on 5% change in accumulation per degree of observed surface temperature change. A slow increase in snowfall with climate warming, consistent with model predictions, may be offsetting increased dynamic losses.

Looks like “Skeptical Science” will have to update their reliance on the “Cophagen Diagnosis” as well as their claim of “Antarctica is losing land ice as a whole, and these losses are accelerating quickly.”:
 
however in fairness I now see some other studies re interpreting grace data and they find loss.
it looks like it depends on the statistical corrections used by the scientists.

in the end add in the fact some of the loss is attributable to volcanoes I see no way to show whether ice loss is attributable to natural variability or not.

So you bring up the GRACE mission observations to support your first argument, now you say the "kibosh" is on the GRACE mission observations?
