a. Warmer temperatures

in Antarctica threaten the

Adélie penguin’s food supply

and reduce its reproductive

success.

d. Scientific models project that ocean water will become increasingly acidic if

human-produced CO 2 levels continue to rise. Shown are computer models for

1995 and 2100 from the NOAA Pacific Marine Environmental Laboratory.

c. Ocean warming and acidification

stress corals, causing them to

become bleached. Photographed

near the Maldives in the Indian Ocean.

b. A coqui tree frog in Puerto

Rico. These once-ubiquitous

little frogs have become

rarer, an indirect casualty

of climate change.

Interpreting Data

In which parts of the ocean

will organisms that are

sensitive to acidification be

most affected? least affected?

How might plants and

animals where you live be

affected by a 2°C increase

in the lowest winter tem-

perature each year? the

same increase in the high-

est summer temperature?
