You may be right. The science may mean this glacier is in fact melting and suffering from global warming. And the glaciers that are retreating? The science may mean that those glaciers are the ones suffering from global warming. The real problem is that today's "scientists" are like todays journalists, too lazy to support their default conclusions:
Hurricane in Louisiana? Bush's fault.
Increase or decrease in rainfall, snowfall, temperature? Global warming.
I'd like to see real analysis, but it's not going to come from the current generation of professionals in those fields. Your explanation could be true, as could a softening of the glacier's core that changes the viscosity or whatever they call the glacial equivalent, but scientists are supposed to need evidence, and they no longer bother.
No, not Bush’s fault. Karl Rove has the hurricane control machine.
