Specification Point 2.13:
Know that Carbon Dioxide is a Greenhouse Gas and that increasing amounts in the Atmosphere may contribute to climate change
Carbon Dioxide & Climate Change
Carbon Dioxide: Greenhouse Gas that contributes to climate change when in increased amounts. Absorbs infrared radiation and heats up. Air gets warm as carbon dioxide absorbs radiation from sunlight.
Greenhouse Effect: Caused by the increased concentration and effect of Greenhouse gases.
Carbon Dioxide and Climate Change:
How the Enhanced Greenhouse Effect occurs
- The Sun emits rays that enter the Earth’s Atmosphere
- The heat is emitted back from the Earth’s surface
- Some heat is reflected back out into Space
- But some heat is absorbed by Greenhouse gasses Such as Carbon Dioxide and is trapped within the Earth’s Atmosphere so causes the Earth’s average temperature to rise as a result
- Climate change due to increase in Earth’s temperature
- Water levels will rise as glaciers will melt because of high temperatures, causes flooding in low-lying countries
- Extinction of species due to inhabitable environment
- Migration of species as they will move to areas that are more habitable (no droughts)
- Spread of diseases caused by the cold climate
- Loss of habitat due to climate change (animals that live on glaciers)
