[Geology2] Re: The Mammoth's Lament: How Cosmic Impact Sparked Devastating Clim



I can see why you are haunted by this, Kim.  Stories of global catastrophes continue to build up, and somewhere in the back of the mind we all keep track of these things.  They tell us how vulnerable the world is and how safe for us and everyone after us.  It is not the kind of stable world I learned about in my geology courses, and I am seriously concerned about where global warming will lead us.
