Just a thought about climate change

Alaska is the land of many, many glaciers.  During my trip, I had the great pleasure of seeing Glacier Bay, the Hubbard Glacier and the Mendenhall glacier.  They are magnificent.  What I found amusing, in an icky kind of way, was the approach the museums, the Park Rangers, and the information sites all took to the glaciers.  To wit:

For thousands of years, since the big Ice Age, glaciers in Alaska have advanced and retreated.  The gorgeous valley or bay in which you now find yourself is the result of retreating glaciers over the hundreds and thousands of years.  This is a natural process.  Except….

Right now, in the year 2010, to the extent some of the glaciers are retreating — it’s all your fault.

Do they even listen to themselves?
