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.

Endangered and Threatened Wildlife and Plants: Threatened Species Status for Emperor Penguin With Section 4(d) Rule
The US Fish and Wildlife Service listed the emperor penguin as threatened under the Endangered Species Act, on the basis of projected loss of the sea ice on which it breeds rather than a documented present decline in abundance. V55 VERIFICATION BASIS: the Federal Register was not reachable during production and no search was possible; the date and rule title rest on the producer's prior knowledge. The Federal Register document number is deliberately omitted rather than guessed.
