Trends in Energy Use
This lesson covers:
- The differences between 'global warming' and 'climate change'
- What causes global warming and climate change
- Some of the consequences of global warming and climate change
The is a layer of gases surrounding the Earth that is held in place by gravity.

Nitrogen
Water vapour
Carbon dioxide
Methane
Argon

Greenhouse effect
warmer / greenhouse / absorbed / radiation / reflected
1Solar from the sun passes through the atmosphere and hits the earth.
2Some of this energy is straight back towards space, and some of it is by the earth and then re-emitted towards space.
3Some of the energy makes it all the way to space, but much of it is absorbed by small molecules called gases.
4These molecules then re-emit the energy and the whole process of absorption and emission happens over and over again.
5This trapped energy keeps the atmosphere and more stable than it otherwise would be.

True or false? Until now, the Earth's atmosphere has always been the same temperature.
True
False

How are global warming and climate change different?
|
One effect of global warming is the of ice caps. This will increase the volume of water in the ocean and could lead to seasonal , or the submersion of entire islands. This is made worse by the fact that water when it is heated, so it will also increase in volume.

What's the difference between the climate and the weather?
|
|
Which of these is an impact of climate change?
Tropical storms will decrease in magnitude
Cases of diseases such as malaria will decrease
Species in affected areas may become extinct
