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 melts before the chicks are ready to swim.
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.
