Key learning points
- Increased greenhouse gases in the atmosphere as a result of human activity are causing rapid climate change.
- Rapid climate change is a problem as people and animals can’t adapt quickly enough to change.
- Sea level rise is one change caused by increased temperatures as ice caps melt and water expands.
- Increased energy in the atmosphere and oceans increases the risk of extreme weather.
Common misconception
The melting of sea ice will contribute to rising sea levels.
There are some great videos of experiments used to demonstrate that only the melting of land ice (e.g. glaciers, ice sheets on Greenland and Antarctica) will exacerbate sea level rise.
Keywords
Carbon dioxide - Carbon dioxide is one of the greenhouse gases in Earth's atmosphere that traps heat
Fossil fuels - Fossil fuels are natural substances that were formed over millions of years from the buried remains of ancient organisms; they include coal, oil and gas
Renewable energy - Renewable energy is sources of energy that can be re-used and will not be used up or run out
Sustainable - If something is sustainable it is able to continue over a long time
Atmosphere - The atmosphere is the layer of gases that surrounds Earth. It includes the oxygen we need to breathe, so it is essential for life on Earth
