Seriously scary....


This is an image from the Extreme Ice web site, taken in 2006.  Click to enlarge.

It shows part of the Columbia Glacier in Alaska.  But the main thing of interest here is the glacial trimline -- the line dividing the dark coloured uplands with snowbanks from the lighter coloured slopes below.  It's remarkably sharp here.  Apparently it marks the position of the glacier surface in 1984 -- that's just 22 years before this photo was taken.  During that interval the glacier surface has been lowered by 400m -- the height of the Empire State Building.

Who says that climate change isn't happening....??
