Why is the ocean important?

• The ocean covers about 70 percent of Earth’s surface.

• The ocean plays a large part in Earth’s environment.

• One of its largest roles is to soak up energy (heat) and distribute it more evenly throughout the Earth.

• The ocean also helps to absorb Earth’s CO2.

How can a water balloon teach us about climate change? 

The ocean does an excellent job of absorbing excess heat from the atmosphere.

• The top few meters of the ocean store as much heat as Earth's entire atmosphere.

  
  

• So, as the planet warms, it's the ocean that gets most of the extra energy.

  
  

• But if the ocean gets too warm, then the plants and animals that live in it must adapt—or die.
