Emperor penguins breed on shelves of sea ice in the
winter. By spring, the chicks have developed waterproof
plumage and are ready to swim in the cold ocean
waters. What effect might a warming climate have on
the penguins? (1 point)
The sea ice freezes earlier in the winter,
shifting the breeding schedule.
The chicks grow faster because of the
warming temperature.
The sea ice melts later in the season,
and the penguins have to travel farther to
find food.
The sea ice melts before the chicks are
ready to swim.
