Singing Stan Rogers' Northwest Passage with friends this evening I realized these days it needs an update. People suggested lyrics, and here's a filked tag to sing after the song:

In this warm clime, I have sailed the Northwest Passage
Opened by our fires, of coal and industry
Tracing one warm line through a land no longer frozen
Until we cool our planet down again
Sequester all this carbon once again

Lyrics by Kip, Mel, Lisa, me, and others.
