calve

Climate change is unlikely to have been behind the birth of A23a because it calved so long ago, before much of the impacts of rising temperatures that we are now seeing.

Farmers often move cattle across great distances, for calving in one place, raising in warm, dry climates, and milking in cooler ones.

Many dairy farms schedule calving to occur in late winter or early spring.

The whales feast all summer long, and only then embark on a 6,000-mile journey south to Mexico, where females calve and nurse their young in the warm and protected inlets along the Baja Peninsula.

As they seep and calve into the sea, melting glaciers and ice sheets are raising global water levels at unprecedented rates.
