What causes Global Warming?

• What is the Greenhouse Effect?

2
Thermal Power stations make electricity A clean
form of energy
3
By burning fossil fuels Like coal oil and
gas. Which releases a lot of carbon dioxide
gas Which is not so clean!
4
Because Carbon Dioxide adds to the Greenhouse
Effect.
5
Carbon dioxide is is called a greenhouse
gas Because a greenhouse works the same way
letting light heat in but not letting it out
again.
6
The Greenhouse Effect is a natural and important
good thing. Without it our planet Earth would
be totally frozen
7
The problem is humans are making the Greenhouse
Effect too strong So the world is getting hot
and bothered.
8
Here are the main greenhouse gases by volume.
Put the Heading Global Warming draw this
graph as a divided bar and describe in writing
what this graph tells us.
9
CFCs are another greenhouse gas. The richer
countries (MEDCs) have banned them. This is
because they stayed doing damage in the air for
1000 years.
10
Methane is another greenhouse gas. A lot gets
produced in cows stomachs. (We could use this
instead instead of burning coal!)
11
Rice paddy fields give off lots of
methane Another greenhouse gas The scientists are
trying to measure how much is released . Because
The concentration of methane in the atmosphere
has increased by about 50 in the last 40 years.
12
So Global Warming is an environmental problem for
the whole world
It is caused by the humans releasing more and
more greenhouse gases adding to the greenhouse
effect.
