SEA LEVELS/WARMING OCEANS

SEA LEVLS

• The sea level has risen 17 cm in the last century.
• In the last decade, the rate has doubled.
• In November 2014, the sea level was 5.95 cm.

2 MAIN FACTORS FOR A RISING SEA

• Melting land ice.
• Expansion of sea water as it gets warmed.

WARMING OCEAN

• The ocean has absorbed much of the Earth's heat.
• The top 700 meters of the ocean is warmed at 0.302 degrees F.
• If the ocean gets too warm, many animals will die.
• The top few meters of the ocean store as much heat as the entire atmosphere.
• As the Earth warms, its the ocean that gets the most energy.

HOW THE OCEAN SOAKS UP CO2.

• The ocean soaks up CO2.
• Water animals breath oxygen and let out carbon dioxide.
• Ocean plants take in carbon dioxide and let out oxygen.
• The ocean absorbs 25% of fossil fuels that humans create.
• But the ocean is becoming more acidic, which affects the animals.
