Lawyers, Guns, and Money has a post which covers an article on a cruise ship cruising through the Northwest Passage.
I follow Powerline, which is skeptical of climate change, along with some liberal sites which accept it pretty much without question. Though I've a knee-jerk reaction that things are probably more complicated than the public discussion makes out, it seems to me this is unambiguous proof of global warming. Real people, not scientists, are venturing real money to cruise through the Northwest Passage, the object of centuries of exploration.
IMHO the rate and extent of climate change may be debatable, but not the fact.
[Updated: Here's a discussion from Politico on how far behind we are in icebreakers--I guess Congress is assuming the ice will vanish on its own.]
