Washington (AP) -- For the past three years, virtually nothing has hatched at Antarctica's second biggest breeding grounds for emperor penguins and the start of this year is looking just as bleak, a new study found.

Usually 15,000 to 24,000 breeding pairs of emperor penguins flock yearly to a breeding site at Halley Bay , considered a safe place that should stay cold this century despite global warming. But almost none have been there since 2016, according to a study in Wednesday's Antarctic Science.
