Over the past 200 years, human activities have put more and more carbon dioxide into the atmosphere. The oceans have soaked up almost half of this, and increased carbon is causing everything from rising seas and warmer waters to changes in ocean chemistry.
Higher water levels will affect humans and many other animals. What's making sea levels rise?
Our oceans are already warming and as they do, some animals will adapt better than others.
The chemistry of our oceans is becoming more acidic, affecting everything from tiny plant plankton to salmon.
When ocean currents change, so does the availability of food for plants, animals—and people.
