The emperor penguin is listed as threatened under the US Endangered Species Act

The US Fish and Wildlife Service finalises a rule listing Aptenodytes forsteri as threatened, on the basis of projected loss of the sea ice it breeds on rather than on any present decline in numbers. It is an unusual listing: the animal is not currently rare, and the threat is a habitat that has not yet disappeared. That is the shape of the argument the whole Journey ends on.

Historical — it happened, and the record is settled.
