Emperor penguins breed on shelves of sea ice in 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?

A. The chicks grow faster because of the warming temperature
B. The sea ice melts later in the season, and the penguins have to travel farther to find food
C. The sea ice melts before the chicks are ready to swim
D. The sea freezes earlier in the winter shifting the breeding schedule

B. The sea ice melts later in the season, and the penguins have to travel farther to find food

As a result of a warming climate, the sea ice may melt later in the season, causing the penguins to have to travel farther distances to find food. This could potentially make it more challenging for the penguins to find food and may impact their breeding success and overall population.
