Changes in local climates can play havoc species and ecosystems. Here Antarctic seabirds had a breeding failure.

In these regions, climate change caused snowfall and snow accumulation to be significantly higher than in previous years. Now, a study published on March 13 in the journal Current Biology shows that these unusually strong snowstorms have interfered with the birds’ ability to breed.

Having zero breeding success is really unexpected.”
