This seems extremely serious, much more than the leaked email affair.  The claim in question has been <i>very widely</i> cited.  PBS Frontline even chose this glacier story to lead off their 2 hour special on climate change:<p><a href="http://www.pbs.org/wgbh/pages/frontline/heat/view/1.html" rel="nofollow">http://www.pbs.org/wgbh/pages/frontline/heat/view/1.html</a> (see Chapter 1, 3:30-6:30.  The actual claim is at 6:00 in the video)
