Uh oh, yet another spear in the Sacred Cow.
Well that took away all credibility this scientist has.
BTW, looking at the photo, it indicates a sub glacial heat source, just from the pattern of surface stress fractures. They are too regular and lengthy to be caused by glacial movement alone.
If it were global "warming", the fractures would not be localized around a suingle heat source.
Notice the surrounding ice sheet has no fractures, or evidence of "melting"
Sometimes I believe these global warming freeks assume the rest of the world is stupid. I know Al Gorp does. Maybe its catching.
Cha-ching!
Get the Japanese or Icelanders in to build a geothermal Spa.
