The first person to walk to both the South and North poles told San Diego City College students he also might be the last because of global warming.
All those millions of people preparing for their North/South pole walks will be devastated.
UPDATE. Reader Ralph has some background on our walker:
I used to work for an evil capitalist multi-billion dollar company called Amway. Robert Swan once gave a talk there (apparently because Amway financed one of his polar walks) and everyone got a free copy of his book ‘Icewalk’.
I wonder if he ever gives any credit to Amway?
(The book has sat on my bookshelf – unread – for years.)
