Kevin, congratulations on a nice article, enjoyable reading, and wonderful images. As an aside, I would like to point out that your mention of "so much for global warming" with regards to lots of snow, is not entirely correct. I read that in the last 50 or 60 years, the temperature in Antartica has risen by 1 or 2 degrees centigrade.
This warming up eventually leads to more snow; some penguin colonies are actually being affected by this extra snow, as it buries their eggs. And then when the snow melts, the ground gets all mushy, and can destroy the eggs. This makes the penguins more stressed, of course. Not good news...
