Evidence:
Our earth is heated by the sun rays that our sun sends to
us. Some of these rays get through our atmosphere while others do not. The ones
that do escape the earth’s atmosphere are called infrared rays. The heat rays
that don’t escape the atmosphere are caught by greenhouse gases. The greenhouse
gases warm the earth to the temperature we have now. Without this ‘cycle’ earth
that we know today would be about 30C colder than it is now.

Health
Sea levels expand when they absorb
heat. That is how they rise. Flooding has become something very dangerous and they
happen a lot more than they used to. Floods are bad because they cause houses
to destroy which makes people lose their homes. Crops or food would be hard to harvest
due to the change of temperature. In order for crops to grow properly they need
a constant temperature. Animals need food which cannot be provided because it
cannot grow due to the change of temperature. Difference in climate also
affects people’s health. Their bodies aren’t used to such change.
Adaptations
Some ways we can help are by
turning off our lights, not using electronic devices so often and recycling.
All these ways could help our earth.
Policies
1.
Kyoto Treaty
2.
Bonn Conference
3.
G8 Summit, Toyako, Japan
We were searching for a way to
reduce global warming in 1997. They also discussed how to reduce heat-trapping
gasses to respond to the impacts that climate change has on us.
