Read here. The IPCC's climate models and its Climategate experts have long predicted that Greenland would lose ice mass due to CO2-induced global warming. Although satellites confirm that Greenland's glaciers in total have dumped massive amounts of ice into surrounding seas during recent years, these same satellites also confirm that generic global warming is probably not the cause.
In actuality, if Greenland was a casualty of unprecedented global warming, then its glaciers would be losing huge ice mass in unison, as predicted by the IPCC. Instead, as the new Chen et al. study finds, there is huge variability of ice loss among Greenland's glaciers, which can't be explained by AGW.
For example, using the advanced technology of the GRACE satellites, scientists determined over the most recent years that:
- Greenland's northwestern glaciers' ice loss increased by: 100Gt/yr
- Greenland's southeastern glaciers' ice loss decreased by: 109Gt/yr
This study's scientists suggest that the gigantic variability (that wasn't predicted) is likely to be a function of regional climate/weather conditions resulting from normal interannual variability.
"A paper published...in the Journal of Geophysical Research finds "the loss rate in southeast Greenland for the more recent period has become almost negligible, down from 109 ± 28 Gt/yr of just a few years ago. The rapid change in the nature of the regional ice mass in southeast and northwest Greenland, in the course of only several years, further reinforces the idea that the Greenland ice sheet mass balance is very vulnerable to regional climate conditions." Global warming allegedly due to greenhouse gases would not be expected to cause such regional interannual variability in Greenland ice loss, thus pointing to shifts in weather instead." [J. L.
