Northwest Passage with Canadian Coast Guard

without comments

Northwest Passage

The territory around the North Pole has been on an international spotlight especially since Russia recently dove in a submarine to the sea-floor and planted their flag down there. Of course, the lure of a shipping route through the North has always been kindling. Global Warming might lead to an ice-free passage in the summer — this is what has actually happened this summer. The BBC has somebody on a Canadian Coast Guard ship traveling the Northwest Passage, and produced really interesting videos and a diary.

One expression that a researcher in the BBC footage uses is “tipping point”, a word that probably came into style since Malcolm Gladwell, son of a University of Waterloo math prof, published a great book with “tipping point” as its title. Within the current context, “tipping point” means the

oft-debated point when the loss of ice and the increase in warmth will result in a permanently changed polar region that defies the ebb and flow of freezing and unfreezing that characterizes the region. (quoted from Arctic moving towards tipping point).

Drinking Water

Franz Alt, some german guy I’ve never heard about before was recently interviewed on his thoughts on global drinking water shortages. He’s not an engineer, but I thought the interview is interesting. While we are in the “general interest” section, here is how water works.


A team of the University of Darmstadt won the “solar decathlon”. I’m not sure who should live in that house, and in what region of the world, but I think it looks interesting. Finally, Georgia might or might not have water problems.
