The abstract of the paper you linked to doesn't say that at all.
It says:
"Numerous volcanoes exist in Marie Byrd Land, a highland region of West Antarctica. High heat flow through the crust in this region may influence the stability of the West Antarctic Ice Sheet"
So it's not conclusive that heat-flow through the crust affects stability of the West Antarctic Ice Sheet. It "may" (or it may not) and the paper doesn't discount other factors affecting the stability of the ice sheet that I can see.
Nowhere does it suggest that climate-change is not occuring elsewhere in Antarctica. That's an assumption and very likely an incorrect one.

Hi Pete,
This is the graph that Wikipedia have,
http://en.wikipedia.org/wiki/File:At..._spredning.gif
to me - CO2 is absorbing in tiny part of the spectrum.
As for the article and site I linked to - well, they're scientific - nobody is arguing about their content. I just found it interesting the alarmism after the satellite article was released - citing possible 10ft increase in sea level - with California Governor Jerry Brown calling for action on climate change because LA International Airport was going to be flooded (even though it's 125 feet above sea level).
I just thought it odd that no one thought it pertinent to mention that the most likely small part of Antarctica to melt - even in pre-industrial times - appears to be melting.
