I've been meaning to mention this for several days: Craig Burrell has declared February to be Antarctica Month at his blog, All Manner of Thing, in part because "February is dang cold," (and he lives in Canada, so when he says it's cold he doesn't mean the temperature will dip below freezing for a day or so). Already, a little over a week into it, he's put together a lot of fascinating information, presented in his usual elegant way. Click here to go to the first entry, and from there you can proceed through all of them via the link at the upper right corner of each post. Unless you're already an expert on the subject, you'll probably learn a lot. And you'll enjoy it (that's an observation, not a command).
