The first thing you notice about Marty is how much effort is takes her to swim. With a paralyzed left flipper, each breath seems a heroic effort—yet she perseveres. Marty is one of 15 (mostly) little blue penguins residing at the International Antarctic Centre in Christchurch, New Zealand. As her feeders kindly but firmly point out, this part of the International Antarctic Centre is not a zoo, but rather a "second chance facility" for penguins.

Global warming, under the notorious "business-as-usual scenario" in which humans go on burning fossil fuels to power economic growth, could by 2100 be at least 15 percent warmer than the worst UN projections so far. And the spread of uncertainty in such gloomy forecasts has been narrowed as well.
Climate scientists had worked on the assumption that there was a 62 percent chance that the world would have warmed on average by more than 4°C if no action was taken to reduce greenhouse gas emissions.
