The Greenhouse Effect 1. Sun’s rays enter the Earth’s atmosphere. 2. Heat is emitted back from the Earth’s surface 3. Some heat passes back out into space. 4. But some heat is absorbed by carbon dioxide (greenhouse gas) and becomes trapped within the Earth’s atmosphere. The Earth becomes hotter as a result. Greenhouse Gases: Carbon Dioxide Methane Water Vapour Absorb infrared radiation emitted from the Earth

If the Earth is becoming warmer because of Global Warming what will this mean for our oceans?
