This series is so well done. The author spent much of last year in the Arctic, funded by a Canadian journalism fellowship. The fruits of his labour -- to date -- are running in the Edmonton Journal and the Toronto Star.
For me, it's the writer's voice that makes it a worthwhile read -- check out Saturday's piece, when he described, in great detail, a polar bear brawl -- but I would also argue (and, I'm sure, be disagreed with by some) that he walks the tightrope of telling the true stories of global warming without getting political.
(Run-on sentence, anyone?)
