Luckily for the penguins, most of Antarctica is getting colder. The northernmost part of the Antarctic Peninsula was never a good long-term option. It’s exposed to not only to the currents of the South Pacific, but also has volcanic activity.
The only major error in the CO2 figures is the implication that CO2 levels significantly drive temperature. In reality CO2 change lags temperature changes, both on the way up and on the way down (temperatures fall sharply from their peak levels despite the fact that co2 is still rising).

Hey couldn’t someone build an artificial ice berg of some sorts and slow population decline? This would be in hopes to allow the emperor penguin more time to evolve to the changing environment. just a thought.

This is a very interesting post. I also wrote a post about how the rise in Antarctica's climate affects the penguin population. You can read it on the bottom of the page here: http://missbakersbiologyclasswiki.wikispaces.com/Matt My post has some information on the specifics of the climate change in antarctica.

According to these projections, levels of carbon dioxide will double from 360 parts per million in preindustrial times to 720 ppm in 2100.

There is some kind of error here. The pre-industrial level of CO2 is usually quoted as 275 or 280 (sometimes 260) ppm. (Current level is about 384 ppm. neat graph .)
